Coaxial speakers are several pronunciation unit layout as one of the speakers, for example, the tweeter is mounted inside the midrange unit; suit speakers and coaxial speakers are the opposite, its pronunciation unit is a separate arrangement, usually with a divider to the input audio signal is separated into different parts of the treble, alto, bass, and then were sent to the corresponding high Woofers replay this divider passive sub- frequency, which is generally unable to meet the players level, but as an ordinary application is sufficient.
Coaxial horn tweeter is located above the speaker, Affordable, compared with the market for initial upgrade car audio friends. Because it drives easy, but because of the treble and bass mix interfere with each other, the sound speaker package as pure. Another sharp sound, the sound field positioning is not perfect, but also its shortcomings, the effect of its music can not keep up with the speaker package as natural. Although some million car stereo also uses coaxial speakers, but in general, split higher grade than coaxial speakers
The speaker package is widely used in car audio, home audio, but is not common. Car audio and home audio are two different things, home audio corresponding to a standard space the effect of the speaker * Montreal play. Car, there are many parts, including the frequency of the dashboard, seats, horn has some obstacles. The car audio industry for this study, the production of a separate speaker package. In general, listen to the speaker package is better than coaxial speakers, and audio level are higher, and hope that in the configuration of a high-end audio enthusiasts, most of the selected speaker package.

Ktv sound more often only know to appreciate, but have forgotten how to install, because the installation is not good, the overall effect of that sound will not be perfect, install audio also need some tips. Like to share with you the next Xiaobian 6 Click Install the sound you need to know!
An electronic device, otherwise it will malfunction. There must be specially trained personnel to install, in order to ensure security.
Disassembly technology: audio-conversion process, the original car stereo removed, whether disassembly is a modification of the fundamental problem, because now dashboard surface can not see the screws, so it is necessary to pry open the decorative parts to see the screws, the demolition operation requires professional and strict, or easy to dismantle bad. The second step, a wiring, dress speakers, it is necessary to removable door panels, door, dashboard, seats, decorative plates, in the disassembly process, the need for special tools, to keep the original intact, otherwise it will not pretty and sealed well to produce noise.
3, whether the product is qualified: many counterfeit brand-name equipment, at the time of purchase must distinguish now on the market, otherwise no end of trouble. Some inexpensive equipment, from the appearance is not out of the quality problems, however, the inner components are inferior, the circuit is designed to not meet the standards, poor sound quality of this equipment do not say, it is prone to failure. even produced naturally. Must be factory authorized shops to buy, to ease of use.
4, how the sound quality? Not buy brand-name products will certainly be nice, brand-name plant varieties can be divided into high, medium and low grade buy is not necessarily nice, the most fundamental work by a professional system, installation and commissioning, to good effect . Not a simple matter of a few lines casually connected, the sound field positioning, phase can not be wrong, otherwise the effect would be disastrous.
5, taking into account the after-sales service: car audio is in motion, environmental degradation slightly, such as: temperature, humidity, vibration, dust, easy to make the sound to produce a variety of failures, maintenance, warranty and maintenance is a very important issue. Cheap parallel imports to buy, renovate and clearance products, theft machine, the warranty card is false, there is no after-sales service, once the damage need maintenance fees, or scrap, whether it is worth. Now store the sale of the equipment is not necessarily expensive, a lot of cost of good equipment, you can enjoy good service, why not.
6, the installation environment: installation of some shops in the open air, and the staff\\ s uniforms dirty, sound installation finished, but the interior of the car and the car looks dirty. Buy a new car sound change is a good thing, but to bring many negative consequences, is a sad thing. Specialty store in the indoor operation, and its benefits, clean, and ensure the car clean inside and outside. 2, independent of temperature, easy to damage when the temperature is too low when the demolition of plastic parts. 3, protected from the weather, rain, wind can work properly. Because of the lighting, so during the day, black day will work. 5, the customer has a good lounge.
These are the professional and non-professional technical difference, this is also the difference between high and low price of non-professional, and ultimately is a value concept, is to choose the price or option value. Do not install the audio as it is an easy thing, not a line to connect audio ring on the bin, not only the sound quality does not guarantee, as well as adverse factors and pitfalls in which, therefore the emphasis to go to a specialty store installation, can be guaranteed.
Knowledge and purchase of my home stereo audio and video cables

The AV cable is short for home stereo audio cable (Audio Cable), and video lines (Vidio Cable). Audio cable video cable, can effectively eliminate external electromagnetic interference, and the original Khan flavor to transmit signals, we say this is a high quality line. A classification of home audio and main functions: home stereo is usually divided into pure audio and home theater audio two categories. Pure sound, also known as HI-FI audio, by the pure power amplifier (only two-channel output), speaker and disc players, generally used to listen to music and songs. Home theater sound, also known as the AV component systems, two-channel playback of music and songs, can also play a six-channel home theater disc. \"Fans\" in the general play of pure sound, but mainly to listen to Western classical music. 2, the relationship between fiber-optic lines, coaxial and decoder and amplifier: the disc player itself can be \"reading\" and \"decoding\", but in order to reduce costs, its decoding functions are generally primary. In order to enhance the \"decoding\" series, so that the sound becomes more beautiful, between the invention of the independent decoder and amplifier with a decoding function, and thus have a connection disc players and decoders, CD and decoding amplifier a \"bridge\" – fiber-optic lines and coax them to disc players \"read\" the digital audio signal transmission to the independent decoder or amplifier with a decoding function decode an audio signal. This transmission is often used in high-end audio. 3, audio cable, video cable, coaxial cable can not mix: appearance, video cable, audio cable and coaxial line of the body and two terminals constitute, and are relying on the inside of the metal wire core transmission signal. Therefore, it was for the sake of expediency, or less demanding arbitrary three mix. This can also lead to communication number, but the sound and picture quality is certainly damaged. Silver Leaf Wang AV cable used in the production of the three characteristics and uses of different structures and materials to ensure a true to the music and images, two functions the same AV cable is good or bad should have conditions: ① both prices and grades must be near; (2) must be used with a stereo, with a piece of music, the same volume, same listening environment; ③ The use audio and yindie of high-grade, too low to itself, will be issued by the noise so difficult to compare. How to give a reasonable sound optional AV cable? AV cable in the audio transmission signal from the \"bridge\" role. According to the AV cable for audio grade matching the same grade, so in order to make the audio sound effects to get better play. In general, high-end audio portfolio, the AV line of the investment ratio of 20% is more reasonable. Generally sound, we can not use too much low-end AV cable, which will not only attenuate the signal and the transmission signal is vulnerable to external electromagnetic interference, and ultimately lead to sound distortion. That are willing to spend money on sound rather than willing to spend money to buy the practice of the AV cable, in fact, with the Mercedes car to the petrol station and 90 # gasoline is no different on the surface, saving money, but eventually lead to bad results. Should be noted that the AV cable in use: the different functions of the line can not be free to mix, for example, use coaxial audio cable replacement, etc.; 2: AV cable when in use so as not to bend, and preferably away from power;: AV cable enough premise should be as short as possible, the extra length will only increase the signal loss; 4: The size of the speaker wire should be selected depending on the size of the sound power. Too small, the signal transmission by stagnation, the speaker unable to pay a good voice; too large, the signal loss increases, the increased burden of the power amplifier, speakers also unable to pay a good voice. 5: AV cable with external connection must be tightened. Poor contact (such as collapse, etc.) that will cause audio noise is severe will cause the components to burn out. : The AV line after a certain number of years, the core has metal terminals and wires may appear oxidation (\"aging\"), which would affect the sound effects, and should be replaced according to the actual situation. Silver Leaf Wang AV cable with 24K gold-plated terminals, effectively put an end to alleviate the \"aging\" of the generation.

TV / home theater / audio-visual works – process – Technical articles: home theater into people s homes already are familiar, however, hidden behind the home theater wiring solutions, but often people understand. Article from the net buy order purchase, for your reference.
For professional engineers to shame the whole home theater wiring Secret
Just got a new house for the master key, the first to a home theater layout is essential for a new home the first line, home theater into people s homes already are familiar, however, hidden behind the home theater wiring scheme , but often people understand. Wide range of cabling is no longer a simple arrangement, combination, if I can not plan ahead, the future home of the beautiful and affecting more than just information technology issues, serious but also has to renovate the destroyed houses!
Small Shao Shao equipment, in Shao Shao wire, big Shao Shao housing. This is the home theater enthusiasts in the more widely spread, the higher word recognition. For the average home theater consumers, equipment and decoration of the proportion of occupied obvious, wire grade so why mention it? Metal wire is not all about the same? I need to be reminded of such consumers is: a small one inside the wire contains a lot of knowledge in, and today I share with you a simple home theater wire knowledge.
Have caused the 7.1-channel compact Full HD Blu-ray Theater
Modern home wiring is divided into three parts, one for telephone, network wiring and other aspects of information systems that ICT (Information and Communications Technology); The second is the lighting, security, monitoring and other aspects of intelligent control system wiring, the CCCB (Command, Control and Communications for Buildings); three on home theater, audio system, home entertainment and multimedia routing, that HE (Home Entertainment and Multimedia). And I share today and the main route is the third category, namely, home entertainment and multimedia wiring.
In order to achieve the most satisfactory results, often before the user should do the wiring in the decoration of planning and preparation. First need to clear the principles of routing, about comfort, convenience, security, scalability, etc. to try to perfect unity. Bright and dark lines in taking the choice, in general, take the open air although you can reduce a lot of trouble to avoid the living room \"cut open laparotomy,\" but the beautiful harmony of the environment there is a certain loss; go dark line is a high capacity for planning requirements, only the pre-well-thought, arranged the layout of equipment and lines, in order to take into account the aesthetic and practical points, or late changes will be more trouble. As for how to choose between two consumers according to their preferences and circumstances to choose. 2
Case of a home theater wiring
Home theater wiring is generally considered a video, audio, power of three parts, the wiring on the knowledge of the three devices I will be in the following article for everyone to detail. Wire with a very interesting topic, but also a very particular knowledge, which requires players to build the process of constantly sum up experience. In all the theater equipment, the wire may only play the role of green leaves, but if you do not have green leaves or green to yellow leaves, then the entire listening environment is missing a lot. Each audio-visual space inevitably will have their own sound qualities, has its own special features, only the wire layout is good, can play a needle-like leaves of the effect. I set all of the above director, summed up some of the wire on the purchase method and the wiring techniques, for your reference.
Structure and function of the audio amplifier
No matter which type of car audio power amplifier (hereinafter referred to as PA), which are composed of two parts, the power
supply and audio section, as shown. The first part of the vehicle power supply filtering, and then by the step-up transformer to
enhance the audio portion of the supply voltage to drive the speakers. Voltage step-up transformer to raise the requirements to
increase the supply current, voltage, the greater the greater the required current.
The audio amplifier section is to be low-level RCA jack input host low-level signals, or high level speaker input signal by the pre-
processing, to after-class power amplifier, power amplifier output to the output part. In the audio portion, but also signal processing
part is divided into pre-and post-class power amplifier part. Pre-signal processing part is when the input signal filtering (high pass, low
pass), adjust the level (volume control), as well as to enhance the low-frequency gain (usually in two-channel or single channel can
amplifiers have this feature ) part. Part of the power amplifier output, but also by the positive and negative signals to drive the
speaker is divided into two parts, two parts by two amplifier tube amplifier to drive, so the post-stage amplifier in the power of the
tube parts are used, respectively, to positive and negative part of the amplified signal. Class A power amplifier, AB etc. is by processing
the signal to distinguish between positive and negative parts of the state.
from the kit into the dark horse On the development of industries and enterprises
Development of the industry actually can clearly see from the development of enterprises, took some time before Jay as a “dark
horse” would appear in our view, the first half of the kit to complete the sales of 120 million, completed the first half of last year
annual sales, including single month in March sales of more than thirty thousand units, will consequently be a “dark horse” called
car subwoofer
Jie into as a 15-year-old company should not have a “dark horse” posture, a good helper has been sales leader, he was a dark
horse to talk about it? I guess not! Jie into the development is not smooth, so good last year, the environment, the kit into sales but
did not significantly increase, but a little behind this year, the overall market is not particularly good, there is a big breakthrough, is this
car mid range
why ? For all manufacturers should have a kind of thinking? How should sum up experience and lessons?
Before the quality of the old saying, ah, ah R & D, selling ah, these people are fully understood, because each manufacturer to
emphasize this, why they have not been able rapid development? In many cases, some of the so-called blind everyone s eyes, the
truth, the truth became the boss of lying lips, especially if the other hand, the industries and enterprises, how do we in this fierce
pro audio
competition it?
Publicity lack of funds, lack of R & D personnel, the lack of quality assurance, product highlights the lack of enterprise
development stagnation, the company s strategy in question, or marketing powerless, why do manufacturers always so at ease, and
most manufacturers really difficult for it? Why some companies for a professional manager, it is completely the same? What is the
operation of the entire company onto a new level, the other hand, our own, whether we are poor in any place? Improve our own
point, breaking point, where?
The overall operation of the smooth, R & D, production, technical testing, distribution, marketing, sale and other integration
operations, interlocking, manufacturers of brand strategy and positioning, dealer promotion, strategy and intensity, this community will
never belong to those thoughtful and strategic people, before we will say, do most of the automotive industry is no culture of the soil
owner, may post as eight thousand and ninety debut, becoming the main force of the new generation, an unprecedented war of
intelligence the future will be filled with various industries, automotive after-market is all about.
Change the pass, the same will die, whether manufacturers, wholesalers or retailers, have to actively search for the next round
way, looking for new growth points, and to build their own unique product line, the development of their own conditions the road
ahead, seek truth from facts, to point to drive the overall development, how to break through, you want good?
A good horse with a good saddle two professional audio battery recommended
As we all know most of the mobile electronic products, the demand for and performance of the battery is very dependent, I
remember ten years ago, alkaline battery has just been published, its durability and performance is much stronger than carbon-zinc
batteries, it is necessary to stress performance electronic products, such as cameras, video games or portable listening devices such as
Yan material. The car is also a mobile machine, also need power operation, the same need for a battery. But one thing is not the
same car with a self-sufficient power generation systems, in addition to supply automotive electrical systems, but also for their
batteries. So the car can keep up to repeated use of the power supply system failure only need to replace aging batteries or
generators.
However, the car is also troubled by the power of energy, if the generator power is too much effect on engine power output and
fuel consumption of vehicles, such as the use of excessive battery load and the generator will increase the weight of the car, So
today s car manufacturers in the design of the use of computing power when the car is very accurate. Because of this, the car s
electrical system can supply us with enough top-level audio equipment enthusiast to install it? Answer is yes, but not enough.
We can take the high-class car audio equipment, but to achieve the best equipment, the power supply is an important factor, and
the car power system control of the important factors. So how to enhance the vehicle electrical system is an important part of today s
car audio. In the past may install and use a large capacitor thick power cord and so on. We are here to give car audio enthusiasts will
bring two cars to enhance the professional automotive power systems.

Readers may ask that any advantage of the benefits of car audio system, but you know, car audio is the main provider of battery
power. In today s automotive electrical system design, when the battery after starting the engine, then to enter standby mode.
When the car built for the computer detects that the battery power consumed when starting the engine, the generator will be
notified of the supplement. The modified audio equipment after the main part is to take power in the battery, which means when
the sound starts after the battery power will often be taken away, while the car has to constantly charge the battery again and
again. One can imagine a high-speed battery charging, capacity and number of iterations of the car battery to power the system has a
good benefit. And has a stable and durable battery is definitely the performance of car audio equipment is very helpful for the Need-
class audio equipment to help even more important.
car audio wire tips The first is a good safety wire requirements
Wire for the emergency vehicle is very sound, and sophisticated requirements of the first wire is safe, followed by a good anti-
interference, attenuation. audio cables and signal lines and power lines, including two major categories.
Signal lines: requirement of a good anti-interference, can reduce the signal attenuation, Bingge delicate, the joints to prevent
oxidation. Some of the top signal line often using special alloy materials, card-ring plug and plug gold plated to prevent oxidation. For
example, the United States monster (monster) brand wire in the audio enthusiasts is Tai Fu Ding Ding.
Power cord: current and voltage requirements of stability, impedance, current attenuation. Selection and power supply cable for
power is often a large current is also large, need to select the thick wire. High purity materials commonly used pure metal wire, a
senior major and enthusiasts will use sterling silver wire. Wrap the power cord insulation material in addition to insulation, but also to
high temperature.
car audio shop to be purchased and installed in the formal
According to reports, which generally are in the car stereo on where to buy equipment, so the store must be in the formal
procurement and placement, acquisition time necessary to complete the warranty card, choose stability of the licensed, or work in the
sale there will be endless trouble . Placement will take time to look for stable staff have pay attention to the power amplifier and the
installation of additional insurance and grounded, then the address must also clean and uniform, it is simply an example of
requirements, while necessary to stabilize all of the wires should be installed after is sitting in the car can not see, can not be free to
pull the hand, power lines and signal lines should also be effectively separated to go, especially the signal line, if the connection once,
then it is not prone to sample noise. A placement of their favorite after car audio, in use should be care of properly, can greatly
extend the life and extolled the good results.
A basic car stereo audio and audio streams into two departments, there is a world changer audio department refers the host, in this
one, now the quality is still reliable than the power of Japanese products, there is a world of Sony, Panasonic and other products are
more public-oriented products, sound quality is not chaos, tranquility, but the nature of the ingredients on low; and Japanese in the
Alpine, Pioneer, Clarion, Denon, middle and other brands of the host is performed more nature, specialization points.
In the audio stream, the included amplifier and speakers, Asian products can play a very balanced, but in general, than the nature of
power shortages, not too prominent premises. In an order to have better results, then it should be more the product of choice in
Europe and America Department, there is a world product of U.S. audio stream is characterized by high power, excellent bass,
European (especially British herein) in the refined product than the force level prominent, and properly appreciate the small areas, no
more than the cost of the product in Asia has an absolute advantage.

Modified in the car audio industry, known as a hatchback sedan better than the discussion of change in sound theory and construction
point of view, indeed justified, hatchback car audio converted to acoustic and bass parts of the former in the same space , so the bass
anyway, leaving modifications and equipment installation technicians handy. The evaluation of the Beijing Jeep Commander, but also
because a large space, sound effects more than the average hatchback advantage of Japan s leading car audio expert Mr. Jin Wen
comment after listening to the car, but also for its craftsmanship, tuning levels are There are excellent reviews, and firmly believe that
Japan participate in the annual Pioneer car audio competition can enter the top three.
System 4.5
This car is a pioneer in China s system configuration 2008 DEMO CAR basic configuration of a template, from the P90 host, to PRS
Series PRS amplifier and speaker unit has a suffix can be seen, the whole system is Reference System-level hi-fi . Pioneer DEX-P90RS, is
the world s first choice for car audio competition level game host, you can 4-way active crossover, and a professional 31-band EQ
equalizer. The main pioneers of the sound field with PRS Series Class D amplifier, small size, light weight, become popular in Japan. SW
series bass system is a 12-inch dual voice coil speaker system closed.
With the P90 high and low two-way active crossover driving enthusiast speaker Pioneer TS-C171PRS, tenor all the way closed. Before
the sound field with the latest ICE POWER technology pioneer amplifier, D class amplifier driver before the sound field may not be
accepted by many leading audio enthusiasts, but will exceed your expectations on the JEEP.
5 minutes car ride modification
Modification in the car ride is the biggest highlight of the instrument panel. The instrument panel and now see no difference between
the original car, in fact, is through major changes. The host bits in the instrument panel has been connected to the air conditioning
control bits of the original ABS plastic accessories, storage boxes will be removed, all mahogany pattern re-processed to fit the two
hosts P90 and 6850 fixed installation and is completely original vehicle configuration , process has been very beautiful, even more
gratifying is that the original car s steering wheel remote control car is also in the same sample can be used.
Modification is the original door style, bass steel plate fixed to the motherboard, but only in the door of the exterior parts, the increase
in the vanguard of LOGO, details of the process has been very fine.
Modified trunk 4.5
Modified trunk modification in the country are fine in class, the conversion does not take up space, refined and elegant appearance. As
the Pioneer SW Series bass is thin bass, amplifier, bass, and other accessories are on the floor, not the space. Trim all stuck with each
other and did not use a screw. Decorative glass sheet at the power amplifier and bass, respectively, decorated with blue and white
LED lights.
Most innovative in the bottom on both sides of the strip, decorated with blue light, a change in the appearance of dull, so that the
whole car full of vitality. As a number of blocks composed of different pieces of molding, the gap between each other more obvious,
while the spare tire so that the average owner can not access it difficult to accept.
Noise damping 4.5
Noise damping of the whole car done Jeep, tap the shell, a very strong and appears to have strong rigidity. Large sound pressure level
in the car playing the track, but this car will have very good damping effect of the subjective feelings, no loose parts of the
resonance, but also did not make the sound muddy aftershocks. With “LOW FREQUENCY” to detect low-frequency resonance, and no
noise.
Sound 4
Pioneer strengths because the host is, after the class is considered sound system sound is not ideal, but the value from the Pioneer
30 million civil fever two channel audio systems, the Pioneer s sound quality in car audio performance should be low are put in that
kind. JEEP voice in voice and high-frequency performance of remarkable. Performance lies in the intensity of low-frequency, low
frequency moderate amount of sense, dive less impressive.
In the sound field set-ups, P90 system can adjust the precision is to the extreme bass sound field can be formed with the positioning
of the former front, restored accurate sound field. Moderate frequency of the dive, which is the orientation of the speaker s own
style.
Tone 4
Jeep in the performance of the Concerto for piano and violin sound when shown can be used to describe gorgeous. Mozart s “Piano
Concerto” under the main piano melody, such as silk thread pull-out violin accompaniment, the piano and violin wood flavor of pine
scent is always very place. Mute the
double bass and bassoon am like a low voice, this is because the performance impact on low-frequency bass voices in the sound.
News 4
Dynamic stress and impact strength of the contrast. In the low frequency part, SW series good performance impact, the vehicle
system in smaller volume, low-frequency performance to highlight the performance of large volume, but the sound volume over time is
mixed. Mid-range speakers in the rated power up to 150W per channel amplifier to drive, and acting freely. In the symphony, the
wooden pipe band performance is better than the performance of brass band, piano performance relatively more pleasant.
Balance of 4.5
Volume in the middle under the balance of the whole band doing well, but in the case of large volume but showed weak treble, bass
and more phenomena. In the “Need Fashao Die” in the first three, the performance of female intimate nature, but the music of drums
on the relative composition slightly. However, the performance in a small volume, the system performed better balance, “Hotel
California” and BASS guitar sounds and drum sounds in the instrument panel lined up perfectly.
Overall Comments 4
Jeep s sound system as a whole conversion, as Pioneer Demo Car is concerned, not the kind of American-style exaggeration and wild,
it belongs to the Japanese refined and details, such as the dashboard, luggage. The quality of performance, the complexity of the
regulation from P90RS point of view, the longer, more able to demonstrate its skill. The system tuning in stereo sound field can be
said that to an extreme, the sound quality on the overall performance, Subvert Japanese speakers can sound a general fallacy.
