The word whispering sound is derived from the "echo wall". The whispering wall means that the two men are facing away from the back to the two walls. One person yells at the wall, and the person behind him will hear his voice clearly from the direction of the wall. The reason why the bridge LS-B211 is called the echo wall sound is that it applies a similar principle. Its characteristic is that it is not placed in front of the TV, but placed behind the TV, which is a veritable echo wall structure.
Although Onkyo took the novel name "Echo Wall Sound" from the LS-B211, it was finally put into the Soundbar when it was put on the market. Because the LS-B211 is a long strip of sound, thick. Long, straight, black is the best statement to describe it.
However, the design of Onkyo LS-B211 is still very different. First of all, it is not a whole. The left and right channel speakers are separated and cannot be spliced ​​with the main part of the middle. Therefore, the LS-B211 cannot be regarded as a Soundbar. Secondly, the main part of the middle is actually the usual subwoofer. Of course, there are DSP, power amplifier and other components inside. It can usually be placed behind the TV. The bass is mainly emitted from the speakers at both ends and the bass guide holes at the back. The reflection is finally passed to the user.
Therefore, the Onkyo LS-B211 should be regarded as a 2.1-channel sound system. It completely subverts the inherent image of the Soundbar, retaining the convenience and space-saving features of the Soundbar, while at the same time taking the desktop audio separation. The advantages of the design can better improve the directivity of the sound. Compared with the rigid and flat sound transmission method of the previous Soundbar, the LS-B211 users can obtain the best listening point by arbitrarily placing two left and right channels.
It can be said that this design of Onkyo has its own starting point. It is not limited to the traditional Soundbar design thinking. Is there any shortcomings? Well, there are still some, for example, its line is really a lot.
The above picture is by no means an exaggeration. Let's calculate the account. Because the Onkyo LS-B211 uses the left and right channel separation design, the left and right channel speakers each need a connection cable, and the wire is a very common speaker line. This is two. Then an HDMI cable or 3.5mm audio cable, a power cord can not escape, and because it must be used with the infrared remote control, so the audio must be equipped with an infrared receiver. Then the problem is, the sound The body is hidden behind the TV. How does this infrared receiver work?
Anqiao thought of a very "wonderful" solution, that is, a separate infrared receiver, placed the infrared receiver under the TV through a cable, so that it can receive the signal from the remote control. Then this is another The root line, a total of five lines. The ordinary Soundbar will have at least one HDMI cable and one power cable. The wireless design of the subwoofer will be calculated. Fortunately, the Onkyo LS-B211 is a hidden design. , no matter how many lines are placed behind the TV, it is harmless.
In order to avoid the cable that is pressed to the TV, Anqiao also provides two feet, which can lift the main body to let the wire pass. The subwoofer body length of the Onkyo LS-B211 is 66cm, two left and right speakers The length is only 15cm. Even if it is added up, it is only 96cm, enough to hide behind a 50-inch TV.
Onkyo LS-B211's own texture is not to say, the surface of the black piano paint looks very elegant. Pay attention to care, piano paint is easy to leave fingerprints and scratches. The left and right channel speakers are not completely In order to match the shape of the Soundbar, it is designed to resemble the shape of a blower. Their sound outlets are set below, and two medium and high frequency units and one bass guide hole are built into the left and right sides. It is presumed that a special sound chamber structure design is applied, and the sound is applied. The effect is amazing, as I will say shortly.
Onkyo has been a fan and amplifier. Their years of acoustic experience have been fully utilized on the LS-B211. This is not an exaggeration, because the first impression of the LS-B211 is a steady, solid voice. No anger, there are obvious differences with some of the same grade of Soundbar's vain sound, the first listen will be addictive.
Due to the separate design of the left and right channels, the main part in the middle is actually the integrated device of the amplifier + subwoofer. The official data is that the subwoofer has a power of 40W, and the power of the left and right channels is 20W. The speaker cable is linked, so we can replace the left and right channel speakers that are included with the LS-B211 with a better speaker. This is also a separate design.
Of course, the quality of the left and right channel speakers of Onkyo LS-B211 is also very good. If it is not the enthusiast above 39 °C, there is basically no need to replace it. Because of the sufficient power, each channel speaker also has two medium and high frequency units built in, so the sound Very balanced, low, medium, and high-pitched distribution is very balanced. For example, in a series of Cooper chasing damaged spacecraft in "Interstellar Crossing", the background music here is full of a large number of symphony dynamic sounds composed of orchestral music, which is very test sound. Quality.
Many home audio systems will focus too much on the performance of the bass, because the bass can bring shocking effects and contribute to the rendering atmosphere of the movie sound, but the Onkyo LS-B211 does not do this. In the scene of Star Trek, its sound is extremely clean, the bass part is not dragged, and the bass flow is clear and easy. The LS-B211's remote control does not have any setting buttons to enhance the subwoofer. It can be seen that Onkyo is confident in the performance of the subwoofer, and has his own insistence, Soundbar should not only confuse people with bass.
In the middle and high-pitched parts, the midrange density of Onkyo's LS-B211 is not very thick, but it is very crisp, so I think the instrumental music on the LS-B211 is far better than the human voice. Its instrumental music is amazing. Strong and grasping ears, especially string music is very silky. This is also its characteristics in the high-pitched, top-notch and outstretched, but also not too harsh, the overall focus is on accurate restoration.
There are also three sound mode movies, clear vocals and music on the remote control. The measured effect is also very good. In fact, you can use it more. The film mode will enhance the horizontal sound field performance of the sound, which is the usual surround sound. After switching to a clear vocal, the gain of the midrange part will be very high, the vocal distance will be closer, but at the same time the density will not have too much loss, how much can make up for the vocal thickness of the LS-B211. Music The mode will weaken certain surround sound effects and give priority to the soundness of the sound.
However, the performance of Onkyo LS-B211 when it is used as a music sound is not so great when playing movies. First of all, its sound dynamic range is still not too wide, the vocal sufficiency is not enough, and the music performance will be somewhat illusory. Secondly it The bass is still a lot, although I didn't feel it when I was watching a movie, but the problem of bass blunt when playing music is quite obvious. The dive is not deep enough, it is very flowing on the surface. It can be seen that the LS-B211 is tuned in the sound of movies. More and more effort. In addition to the relatively large power, its ability to play music is not better than many desktop audio, although it also supports Bluetooth connection playback, it does not matter if you listen.
Finally, let's conclude, Onkyo LS-B211 is a sound that is completely created for film sound effects. It not only can make the film atmosphere, but also has a very strict grasp of the tri-band, and there are few out of control situations. Any scene can do the right thing. I think the LS-B211 is a 2,000-yuan Soundbar in the expression of the movie sound. Its quality is very good, quite lively, there is not much to be worthy of picky.
Here, because of personal preference and the convenience of taking pictures, the left and right channel speakers are placed on both sides of the TV. In fact, if you are looking for a beautiful home environment, it is no problem to put the LS-B211 as a whole behind the TV. The sound is pointing completely in front, just passing through the gap under the TV. The ordinary Soundbar is usually placed in front of the TV due to the volume limitation.
It can be said that Onkyo LS-B211 is the most exciting TV sound this year. The steady sound quality is on the one hand, on the other hand it only sells for 1980 yuan, or the official price, it is really affordable. Don't want it. When I am one When the colleague heard the sound of it, he immediately asked the price, indicating that the quality of the LS-B211 is really good. If the living area of ​​your home is not too big, you need the hidden design TV sound of LS-B211, then it is No need to hesitate any more. If you are a movie lover, then LS-B211 is definitely suitable for you. The experience that Anqiao has accumulated in the field of power amplifier for many years is really not covered. I only have one proposal for the product, next time Anqiao Give a fiber interface, and also take care of those TVs that do not have an HDMI ARC interface.
