Subwoofers are an under appreciated component in audio systems. But they are also the key to unlocking a system's full potential. Few speaker systems are truly full-range, and even those that are could benefit from decoupling the deep bass reproducing drivers from the rest of the speaker. And for home theater, choosing the best subwoofer you can accommodate is a must!

Whether it's viewed through measurements or subjective empirical experience, the best subwoofers prove their worth time and again by playing deeper, hitting harder, and allowing for more flexibility in conquering the challenges involved with reproducing deep bass.

Subwoofer Types: Sealed vs. Ported vs. Passive Radiator
Subwoofers come in all different shapes and sizes. Ported subs tend to be larger but they feature a tuned port that increases their efficiency. If you seek maximum bang for your buck and high impact in a home theater application, you should probably check out ported designs. The primary limitation is that output drops dramatically below the "port tune" frequency. Also, badly ported designs can suffer from "chuffing" which is a distorted sound caused by air moving too quickly through the port. Some ported subwoofers allow you to plug the ports, effectively converting them into a sealed design. Sealed subwoofers tend to be more compact. You might not get as many dB per $ as ported, but sealed designs behave very predictably and output drops off much more gradually in the lowest frequencies, versus ported subs. Some listeners prefer sealed subwoofers for music.

Passive radiators look like the cone drivers found in subs but instead of being connected to a motor, they move freely. When the sub is playing, they move in unison with the active driver due to the pressure changes in the otherwise sealed box. Adding weight to the passive radiator allows subwoofer designers to "tune" them, so in practice, they perform a similar task to a port. The main difference is they do not suffer from chuffing and can be tuned lower while fitting in a smaller enclosure, but this comes at the cost of some efficiency versus ported subs.

Subwoofers are a Must-Have for Home Theater
Your AV receiver will thank you for adding a sub. Bass eats up amplifier power and when you add one or more subs and use bass management, you relieve the AVR of having to move all that air. Instead, the amplifiers built into active subs take care of that business, contributing hundreds, and sometimes thousands of watts of power to the overall system. (most consumer subs are active i.e. self-powered).

With subs, bigger usually is better in the sense that physics demands a large sub if you want to play really low. "There is no replacement for displacement" is an axiomatic expression when it comes to subwoofers and deep bass! But it is also true that you can achieve high displacement by utilizing multiple subwoofers. And when you have multiple subs, you can distribute them optimally throughout the room in, order to reduce the peaks and dips in response that are caused by room interactions. Alternately, you can buy one monster sub that, once optimized for your listening position, allows you to split atoms and create portals to new dimensions... Or at least enjoy the infrasonic sounds found in some music genres as well as some movies.

Not everyone needs a monster sub, or multiple subs—that tends to be for home theater. If you're listening to music at moderate levels, a more modest subwoofer will typically cover the frequency range found in most music recordings. However, if you do not have an AV receiver that includes room correction, you will probably want to look for a subwoofer that has some sort of built in EQ and other DSP functions.
