What is a subwoofer:

A subwoofer is a type of speaker that reproduces only the lowest of audible frequencies. In-home theater, this is often referred to as LFE (Low-Frequency Effects).

Home theater surround sound is implemented by 5 or more channels, with each channel represented by a speaker. The surround sound channel dedicated to the subwoofer is referred to as the one channel.

With home theater sound systems requiring specialized speakers for center channel dialog, main soundtracks, surround, and sometimes even height effects, the need for a speaker to reproduce just the deep bass portion of a movie soundtrack is more important. A home subwoofer is not quite as “thunderous” like the ones at the local movie theater, but it can still shake the house down or annoy the downstairs neighbors in your condo complex or apartment.

Types of subwoofers:

Passive:

Passive is a type of subwoofer is powered by an external amplifier, in the same way as the other speakers in your device. If using this type of subwoofer, keep in mind that extreme bass needs more power to reproduce low-frequency sounds. This means an amplifier needs to be able to output enough power to sustain bass effects via the subwoofer without draining the amp. The value of power depends on the requirements of the speaker and the size of the room (and how much bass you can stomach!). (buy audio amplifier board)

Powered:

Powered subwoofers combine the subwoofer speaker and an amplifier inside the same cabinet. All a powered subwoofer needs, in addition to AC power, is a line output (sub out, LFE out, or pre-out) from a home theater receiver in order to operate. This arrangement takes a lot of the power load away from the amp/receiver and allows the amp/receiver to power the mid-range and tweeters more easily. Most subwoofers used in home theater setups are the powered type.
