DESC: Most large floorstanding home theater speakers deliver good bass response; but remember that extra dimension of deep, rumbling, realistic bass you experienced at the movie theater or concert hall? Infinity knows how critical low frequencies are to the full enjoyment of today''s high quality multichannel digital music and movie soundtracks. Infinity''s PS212, 12-inch, 400-watt powered subwoofer delivers that same rich, clear, dynamic bass response right in your own home.
