How to Choose a Home Theater Subwoofer and How to Place It？

Q1: How to choose a suitable subwoofer?

Not only a home theater needs a subwoofer, but listening to music can also benefit from the powerful low-frequency effect of the subwoofer.

The size of the subwoofer is not the bigger the better, it is best to match the speaker size of the main speaker and the size of the room. Generally, a 12-inch active subwoofer is sufficient for a room of 20 square meters, and a 15-inch subwoofer can be used for a room of 40 square meters to obtain a better wide dynamic range to bring sonic sound.

Q2: Which type of subwoofer is better to choose?

1. The bottom bass reflex design speaker has a bottom bass reflex design hole on the speaker panel. Because of the hole, the sound inside the box can be radiated to the outside. Tonewinner's SUB-1280B subwoofer is a bottom bass reflex design speaker, characterized by full low frequency, and can withstand greater power and lower distortion.

2. The enclosed speaker is sealed except for the speaker port, so that the front and rear of the speaker cone are divided into two spaces. Since the inner and outer spaces of the box are isolated from each other, the phenomenon of acoustic short circuit and mutual interference can be eliminated. It is characterized by simple structure and good transient response.

Usually, the low-frequency dive of the enclosed design woofer is a little bit worse, and the response is sensitive and fast. bottom bass reflex design woofers have better low-frequency extension, but the transient response will be worse.

Q3: How to place the subwoofer?

"The subwoofer is the soul of the home theater system." If you want the subwoofer to perfectly reproduce the low frequency, you need not only a high-quality subwoofer, but also a reasonable adjustment.

The subwoofer can be placed anywhere in the room, because the bass is non-directional, but the subwoofer pays attention to the phase. In order to reduce the standing wave generation in the listening space, the placement of the subwoofer still needs some time to adjust.

When debugging, try to achieve the same phase, that is, let the sound of the main speaker and the subwoofer arrive at the same time. If there is no problem with the frequency connection, it sounds that the sense of speed of the two will be the same and blend with each other. We also recommend that the volume of the subwoofer not exceed 80% of the maximum volume, otherwise it is likely to cause distortion.

There is a simple subwoofer positioning rule, that is, the closer the subwoofer is to any wall or corner in the room, the stronger the sense of low frequency volume you can get. If you want to get the most sense of ultra-low frequency volume, you have to place the subwoofer directly on the floor in the corner.

But if there is too much energy rumbling, you should avoid placing the subwoofer close to the wall. 

When you find that the whole system can satisfy you in all aspects of combination, including smooth frequency response, impactful low-frequency subwoofer performance, and no rumbling sound that makes you feel uncomfortable, then this is the best place for subwoofer. Good placement.
