Advent subwoofer

This is a downward firing powered sub. The approximate dimensions of it are 1 1/2 ft by 1 1/2 ft by 1 ft 8 inches. It's a great sub for music and movies and tunes easily by using the volume control on the back and room placement. The cooling fins are over engineered so it will have no problem keeping up with the rest of your system. This Advent has been in my system for about nine to ten months now and I'm only selling it because I acquired a rare NHT monster sub at a price I couldn't pass by.
