Sound quality! The height of the speaker stand is crucial, are you neglecting it?

Nowadays, it is in the midsummer season. The weather is hot and dry in the evening. After the meal, the air-conditioner watching TV has become the way for many office workers to rest before going to bed. They use flat-panel TVs with small speakers to meet their audio-visual requirements. Some of the philosophers also have a bookshelf speaker and a tripod, so that they can sit in the center of the TV and the speaker, and listen to the songs in the sofa. Think about it, if you want to fully enjoy all of this, you should pay attention to the height of the TV. In fact, the same is true for speakers, they have the best listening height. This height is determined by the height of the speaker stand. From 20 cm to more than 1 m on the tripod, how to choose the most suitable one? This problem is a blind spot for many old enthusiasts. To systematically explain this problem, we need to empathize from the perspective of the speaker designer, starting from the design and development process of the speaker.

In the design test process, you need to select a "test point" to do a directional index test to meet the default industry standard of vertical range of +15 degrees -5 degrees, horizontal range +30 degrees -30 degrees, thus giving The test parameters are the basic indicators for the quality of a pair of speakers. Then, specific to each pair of speakers, the listening axis test point selection is different, it is affected by the specific form of the frequency division design and the independent directivity characteristics of the speaker unit itself. But they all meet a final goal, that is, the listening axis test point must be the point that the overall phase change is the least (close to 0 degrees). Generally speaking, this point is the highest synchronization after the high and low-frequency synthesis, and the phase change is the least. It is closest to the overall ideal listening point that sounds like a speaker unit. Try to match the best listening axis test point of this speaker with the height of the human ear. This is the best speaker placement height, not the average friend thinks that the human ear and the speaker's treble height are the same, which is very A general and superficial understanding.

Take the ACM SCM7 bookshelf speaker in the United Kingdom as an example. The listening axis is basically at the axis of the woofer. If you choose the height of the stand, you should choose a higher size than the matching speaker stand, so that you can listen and listen. The axis corresponds, otherwise how to adjust other equipment will feel the sound field distribution is not ideal, high and low bass connection is strange, and will eventually distort the correct direction of adjustment, BBC 3/5a speakers also fall into this category.

Most of the Dynaudio speakers have their listening axes near their tweeters, so it should be understood in a traditional way. It is better to choose the height of the human ear and the tweeter. But for most of the two-way bookshelf speakers, the listening axis test points are near their tweeters, because this is a design mainstream. Therefore, what the average person knows is that the "high pitch and the human ear are flush" is a general summary of subjective experience, which is also reasonable.

The speaker stand not only needs to be beautiful, but also matches the acoustic characteristics of the speaker. High-fidelity audio is not metaphysical, not as fascinating as some people say, but some necessary rules must be observed, because adhering to these principles can make the improvement of sound quality more effective, so that your equipment can fully play its role. There are levels.
