Analysis and treatment of low frequency standing wave problem in home theater

Almost every day, people ask questions about the low frequency standing wave of the home theater subwoofer. Here are some of the reasons for this:

Standing waves have a lot to do with the sound of the room, so there are often friends who say that the effect of the subwoofer is not right.

What is said below is how the standing wave comes from, mainly because of the reflection. The same wavelength and physical size mean that the two waves in the forward and reverse directions are completely superimposed and the loudness is doubled, the energy is doubled, and the natural volume is also increased.

There are standing waves in a room, inevitably, only to varying degrees

The following is the standing wave state that is possible when there are no other obstacles at all, and the dark color indicates that the standing wave is strong.

This is unavoidable and can only be reasonably 'avoided'.

This is relatively complicated, and it needs to be adjusted by the tester. The ear is not easy to distinguish.

4? The private money in the small treasury is not enough!

EQ is the last active means to clean up the low-frequency standing wave. This relatively advanced is also more complicated. It can be discussed and shared later, WeChat: cnhifi.
