Alright, I'm sold! (litteraly) I'm going with the XCON. I'll power it with the Rockford Fosgate T-500 db, if I want more volume later I can just replace that with a T-1500.
I'm going to order a box design and get my buddy to help me make it out of 1" birch. We'll spend some time on BCAE1.com, they have great box building tips. Now for the question...
Can SSA design a bandpass enclosure that yields a flat frequency response from about 35 to 85 HZ. I know prefab bandpass boxes are total crap, but if I can get a good response curve and output I would love to make the box and cover it in bedliner and never have to worry about it. If the XCON does not play well in a bandpass, I'll get the ported and good speaker grills.
