Okay, this is about home theater subwoofers. This is one particular type of home theater subwoofer. It's a component type. It kind of looks like a piece of stereo equipment. It can be placed in a rack or a cabinet. It can also be set aside right on the floor, out of the way, behind a couch. What a home theater subwoofer does is it hooks up to your home theater receiver here and this receiver delivers just the very low frequencies to the subwoofer. This subwoofer also needs to be plugged in because it has a power amplifier built in. Those low frequency signals are amplified by the amplifier inside this device, passed to the speaker inside this device and it creates a very low, very powerful, punchy bass response. So when you're watching a movie in your home theater system and you see a gunshot or an explosion, you actually can feel it as well as her it in the room and this is the device that produces that that sound.
