Ok guys, i've had an original SVS 20-39PC sub for like 2 years now in a 11'6" X 10'6" room. I'm finishing my basement right now. The finished demensions will be roughly 20' X 15' with a split ceiling height of half- 7', other half 8'. No other openings.. With a budget of roughly $1500.00 which way should i go here ? Any other suggestions on the best way to maximize my bass budget ? I do not want to build a sub.. I want the lowest & loudest i can get within my budget with the focus 70% movies - 30% music. Thanks.
