AudioSource PSW100 100 Watt 10-inch Powered Subwoofer (Discontinued by Manufacturer)

This puts the thunder in the picture pretty darned well. Be careful setting this up, as the speaker is pointed downward and when you pick it up you are touching the speaker if you are not careful.This took a while to get sounding right. It was too boomy but simply adjusting the distance from the walls and changing the direction of the tuned port solved this problem. I'd buy it again.

First let me say this sub delivers excellent sound at an excellent price.However I was disappointed to discover that whlie the product description says it is "autosensing" for power----that is not the case. There is no auto position for the power switch.Other than that inconvience it is an excellent buy.

This sub delivers an awesome amount of bass for a very reasonable price. The controls on the back make it very easy to control the level. I can shake the entire house if I feel like it, or turn it down and enjoy some nice subtle low tones when it's too late for an earthquake. I would definitely recommend this sub for anyone.

After 3 years the unit started buzzing when turned when on or when on auto. Buzzing continued with the audio-in cable attached or un-attached. Not sure what happened, but it is a year out of warranty and its is easier to replace it than try to get it fixed. I went with another brand.

This subwoofer does sound good, but it does not have auto-on signal sensing - that is not mentioned on the box anywhere, and it pulls ~15W constantly when not in use.

not bad for a low end sub. it works fine for my room.

Good buy, just not what I wanted. Very nice speaker for first time owner.
