Hi there. I'm now on the process of getting a new sub. I am moving now to the basement and I need your tips on which sub to get. I am looking at axiom EP500, SVS 20-39 pci (320 watts), or 20-39- pc plus (525 watts).

My basement is 15 x 18 (around 350 sqft 8 ft height).

Do I really need a 500 watt subs or can just settle with 300 watt sub. I've heard the SVS 20-39pci and it was fun. It was at a media room at the second floor and just wondering if I wiil get the same subs quality if I'll have it on the basement (concrete with 9 pound underlay and 50 ounce carpet on top).

Your advice is mostly appreciated.

BTW, I Have HK 335, M60tis, 4 Qs8s and VP150.

Cheers,
