EQ-Max 15 Inch Subwoofer

Product Review (submitted on March 24, 2012):

This makes me happier than almost anything I've ever purchased. Luxurious, powerful and tightly-controlled bass adds a layer visceral impact to everything, even old stand-bys that I've heard 1000 times.

I had a good sub before but this takes it up a level or two. LOVE.
