Thanks for the input guys! I think I have settled on 2 RE SRX 10's in a sealed box. The Xmax on those is 18mm! That's w7 territory for 1/3 the cost! I am a carpenter and I will be building my own box. If I'm not happy with a sealed setup, I'll make a ported box.

 

if you're looking at those, another sub that I'd recommend you look into is the Creative Sound SDX10

XBL, 18.4mm Xmax, 300w RMS power handling, and dirt cheap for what you get IMO.

 

Thanks for suggestion! I just bought 4 RE SRX10D2's for $385 shipped. 2 are for a buddy who trusts my judgement. Hopefully I don't let him down! lol
