An integral part of any home theater system is a subwoofer. After all, it reproduces special effects such as explosions or, for example, rolls of thunder. Naturally, without a full and close to reality transmission of these sounds, the effect of watching movies on your home theater is far from complete. Furthermore, the presence of a subwoofer in the acoustic home theater system removes low-frequency spectrum of the signal that is supplied to the main loudspeakers. And at the expense of quality and better reproduction of low frequencies, the picture becomes the most dynamic and realistic. Thus, there is a problem of choosing the best subwoofer according to your requirements. Let's try to understand the difficulties encountered and try to make an approximate "portrait" of the subwoofer for a typical …show more content…

Main Differences Between The Systems When choosing the best home subwoofer, for a start you need to decide the type of acoustic enclosure of subwoofer driver. There are quite a large number of different options, but the most common are three types: closed, vented, and bandpass. Each of the options has its advantages and disadvantages. Let's consider each type more in detail because housing construction largely determines the acoustic properties of a good subwoofer. Sealed (closed) box Models of closed type are the same dynamics, but they are built in the box of a certain volume. This is the most common type of acoustic speaker design. Fluctuations in this box are in a closed volume and eventually, they are extinguished. But as a sound wave is an energy, the fading of it is converted into heat. Although the amount of this heat is very small, it still has an impact on the acoustic characteristics of the
