Monoprice SW-12 400 Watt RMS 600 Watt Peak Powered Subwoofer - 12in, Ported Design, Variable Phase Control, Variable Low Pass Filter, For Home Theater

I already had this subwoofer's big brother, the Monolith 10". But, I didn't want something that expensive, nor that powerful, for my bedroom system. However, I did want a subwoofer that would be able to handle all the low frequency sounds, plus get a bit loud if needed. This subwoofer is everything I wanted. First, I think it should be noted that this subwoofer has a very powerful amp which helps a lot! Low bass notes require a lot of energy to push and the amp in this sub is 400 watts, powerful enough to do the job! It doesn't get quite as low as my Monolith amp does. However, we can't really hear those notes that are that low, but we can feel them. That being said, this subwoofer gets quite low. The specs say it can reach down to 33 Hz which is almost as low as we can hear. The subwoofer can reproduce rumbles for earthquakes and explosions very well and also handles music with aplomb. I think the sound is not as tight as the Monolith, but its quite acceptable to my ears. It is ported on the bottom which helps it get those low notes. It has a switch to change phase, too. Basically, I see this amp as a smaller, less featured version of the Monolith. If you are putting together a home theater and need a subwoofer, but can't afford a Monolith, then this is a great substitute. I recommend it without hesitation to anyone looking for good bass without breaking the budget.

Amazing subwoofer for the price, I have the big brothers in the home theatre room so I decided to try these out in my living room/gaming room and these are almost as good as the monolith's. They almost pressurize the room, the Monoliths get lower and louder but these are pretty amazing for the price. I would highly recommend.
