<br> into the wall speakers, the name suggests is a can be installed inside the speaker in the wall. .The biggest feature is the speakers to save space, while well-concealed and does not affect the overall room design. .In the home theater systems, hidden speakers into the wall of the performance the audience's attention is more focused on the screen above, therefore, into the wall of speakers in Europe and America developed countries have been warmly welcomed. .Therefore, in this issue, we organized a special event planned speakers into the wall of the topic, and its characteristics, installation, and be aware of when buying a place were introduced one by one, to let potential readers of this audio-visual .New models have sufficient knowledge and understanding. .Describes the content of any deficiencies, but also hope forgive me and correct me. .Among the magazine in the future, we will introduce more into the wall of speakers on the practical application of case, hoping to play a guiding role of the consumer. .<BR> <BR> Status of the speaker into the wall <BR> <BR> In the past, most applications into the wall of speakers in the hotel, theater, public address system and other areas or situations, which are mainly used to play background music. .In general, these speakers into the wall in terms of the production process and performance indicators with the traditional home speakers there is a certain gap. .Therefore, the performance of the sound quality can not be compared with the traditional home to be the speaker. .However, most consumers years to continuously improve the quality of interior design and production of more and more professional loudspeaker manufacturers to use its own technology into the wall to join the ranks of the production of speakers, wall speaker is the sound quality of the production level and continue to .improved, so that they gradually become home market. .<BR> <BR> <BR> <BR> <BR> Sold into the market at present is generally divided into two kinds of wall mounted speakers. .The first is the in-wall speakers (In-WallSpeakef), this type of speaker can be installed in front, rear, left and right walls, and in the number of speaker units are also used more generally in the 2 .above, and thus volume also increases, the price is relatively expensive, is also present in the highest rates of home theater system, one of the products. .Like M & K, B & W, KEF, AtlanticTechnolony (Atlanta), SnellAcOLISitcS (rhyme), JMlabFocal (Jin Lang), Genelec (true power), Trlad other brands have similar products. .Another is the ceiling speakers (In-CeilingSpeaker), also known as the ceiling speaker. .The speaker and the former difference is that it is mainly installed in the ceiling, is very suitable for study, bedroom and other small area of space used as the background music playing. .In the speaker's appearance, we have a common ceiling baffle speakers are generally the first round, because of its relative use of the former speaker volume is less, in general, in two units or less, so much smaller, .prices are also cheaper than the former. .Speaker into the wall above the market price is usually calculated alone, consumers according to their actual need to purchase the number of speakers. .<BR> <BR> Advantage of the speaker into the wall where the <BR> <BR> Why are so many speaker manufacturers to launch their own horn it into the wall? The same time into the wall of speakers, compared with the traditional home-style speakers, built .Speaker of the advantages in the wrong? on this issue, and if so from the perspective of interior design, there will be the speaker into the wall cleverly installed in the wall speaker, the speaker not only to reduce the traditional use of the area occupied too much room, and .home audio and interior design can integrate with each other, so that the layout of the room is much more clean and comfortable and beautiful, this is one of its greatest strengths. .But if we have the technical analysis of the speaker into the wall, then we will find the speaker into the wall with solid walls can be easily solved by traditional home speakers need to address the noise problem. .<BR> <BR> Sound diffraction to solve: What is the sound diffraction culprit? Is the speaker cabinet itself. .The unit is not the only sound way to the front of the energy, as well as open to the expansion of the energy in all directions, so the edges and corners on the box next to the alt likely to cause diffraction. .Diffraction severe, it may cause interference, which affected the sense of high frequency energy, reducing the sound imaging and force. .As for how to reduce sound diffraction, which is one of many speaker manufacturers one of the most headaches, they exhausted all means. .The easiest way is to buy a piece of thin foam or cloth, cut into small pieces, then stick around in the tweeter (for example, commented ELACBS244 Issue the means used by speakers) can be improved. .More exaggerated way, is like WesflakeAudio (West Lake) will be the speaker company that chunks of foam embedded in the center. .While this is definitely on the immediate improvement of the sound, but its visual effect is extremely poor. .The best way is to try to expand the baffle to reduce sound diffraction, and the wall is the use of large wall speakers as a sound baffle diffraction to solve the problem. .<BR> <BR> Address box shock: shock box but the biggest enemy of speakers, this is because the shock will bring the speaker cabinet coloration produced, affecting the sound faithfully restored. .How to make a more robust and free box to shock effects? The traditional practice of home speakers in the cabinets using a variety of reinforcement measures. .Support such as wood frame, with internal partitions, etc., are more rigid box to enhance a good way. .The speaker will use some of the top metal as a box, hoping to use the weight of the metal box to suppress the vibration. .For example YGAcoustics, WilsonAudio other brand is representative of the metal box. .For the speaker into the wall, the wall is not only outside its front baffle of the box but also the equivalent of it. .Therefore, if your house wall has sufficient strength and thickness, in theory, this can easily solve the "box" of the vibration problem, send speakers into the wall so that more realistic and more accurate sound. .<BR> <BR> Buy into the wall of the speaker should pay attention to what <BR> <BR> <BR> <BR> speaker into the wall in the market as more types of consumers in general may be some .question. .How exactly should I choose? And in the choice of when to pay attention to what? In this, we would like to purchase for this part of the speaker into the wall, the following summarizes some of the points of consumers for your reference. .<BR> <BR> 1. .Frequency Response (Hz): I believe the majority of readers for this indicator is not strange. .Because it is an important indicator to measure the merits of one speaker. .In theory, the wider the frequency response of speakers meant to re-emit more sound signals. .The human ear can hear sounds between 20Hz-20kHz range. .But in fact, the existing products are basically very few can achieve this target, especially in the low frequency limit, we should reproduce the 20Hz frequency is very difficult. .As for the general speaker into the wall, its low frequency limit of 50Hz has been pretty good reach, while the frequency of 50Hz to reproduce the following is basically an external subwoofer to complete. .<BR> <BR> 2. .Sensitivity (dB): Speaker sensitivity is at a specific frequency to the speaker input 1W (2.83V or 1V) of power, then the speaker is the location of the measured axis sound pressure. .This value is equivalent to speaker efficiency. .In the case of the same input power, the higher the sensitivity of the Speaker of the output sound pressure will be high. .In other words, the higher the sensitivity of the speakers at the same sound pressure, the less power required. .In fact, today in the pursuit of efficiency, most manufacturers produced by the speaker of the sensitivity remained at a high value. .Therefore, consumers who do not have to worry about the choice of amplifier. .<BR> <BR> 3. .Power carrying capacity (W): Now almost every manufacturer will be given the power of this product is the recommended carrying capacity or if the reference amplifier power, and similar indicators. .Therefore, consumers can use their own amplifier and the combination of the reference value to select products that match. .For example: given speaker manufacturers recommended amplifier power is 30W ~ 150W, then you can use a 150W amplifier output power to match. .In fact, the speaker of the actual carrying capacity of the power is higher than the reference value. .Even with a higher nominal power amplifier speaker would not pose a great impact. .<BR> <BR> 4. .Movable type Tweeter Design: There are parts of the tweeter speaker into the wall to be movable design, which according to the actual needs of the consumer's point to point on the tweeter to fine-tune the sound to get better .. .<BR> <BR> 5. .High, the bass Function: This feature can be based on different consumer listening preferences and listening to the acoustic properties of space to make appropriate fine-tuning. .For example, a strong sense of rhythm are you listening to pop music when the bass can be enhanced for certain low-frequency to be more abundant; when listening to music Shiyou lively sense of rhythm can be some increase in frequency. .However, not all of the products currently on the market all have this feature. .Therefore, you can choose one with a high, the bass amplifier to adjust the regulatory function, can also achieve the same effect. .<BR>.
