Subwoofers are easily overlooked in home theater systems, and even many enthusiasts did not buy subwoofers at all when building a home theater system. But in fact the existence of the subwoofer is very necessary. The subwoofer is specially used to present the subwoofer effect in the home theater. It is mainly responsible for broadening the frequency range of the sound and increasing the low-frequency energy, thereby showing a better movie dynamic effect.

Since the subwoofer is so important, how should we choose the subwoofer in building a home theater? How will it be arranged in the future? After reading this article, you will understand!

Types of Subwoofers

Because subwoofers with different box structures have their own characteristics in sound effects. Generally, subwoofers are divided into closed type and inverted type.

The inverted subwoofer has an inverted hole on the speaker panel. The sound inside the box can be radiated to the outside through the opening. It is characterized by wide frequency response, high sound pressure and deep dive. Dive deeper when expressing large dynamic effects, and when watching movies in the "emperor's position", you will have an amazing experience of blowing the trousers.

The characteristics of the closed subwoofer are that the structure is relatively simple, the transient response is good, and it can withstand high power, and the box area can also be made relatively small.

There is no absolute distinction between the two, each has its own merits. Customers can choose according to their specific usage scenarios.

In addition, the subwoofer has different materials such as solid wood, density board, aluminum board, etc., and the acoustic performance is different. Most of the subwoofer boards on the market use medium density fiberboard (MDF), which is a widely used man-made board, which can effectively reduce resonance and echo.

How to find the best placement for the subwoofer

Although the bass has no directionality, the subwoofer pays attention to phase.

Phase is a way to delay the input signal of the subwoofer, and its purpose is to obtain consistent output signals with other speakers; by adjusting the phase, you can better explore the "limit" of the subwoofer, and better cooperate with the home theater speakers. Create a flawless movie-watching experience.

There is also a more common way to find the location of the subwoofer.

First place the subwoofer at the place where you listen most often (that is, what we often call the emperor's seat), and then play some music to test the bass after connecting it to the power supply. Dwell at various points in , looking for the most pleasant-sounding low frequency.

When you find that the entire system has a smooth frequency response, strong low-frequency performance, and no unpleasant booming sound, then this is the best place to place the subwoofer.

Of course, qualified audiophiles can also use professional instruments to test, so that the sound details can be presented more accurately!
