Default Which sub would you use?

I'm not done with my current project and I'm already thinking about some subwoofers. I bought 2 sub amps that are replacement amps for the sub amps 315HO Acoustic Research speakers. They are rated at 500 watts RMS and are said to be a sunfire designed amp. They have a 100 Hz LP x-over, I think it's either 24 db-octive slope or 36.

I'm trying to chose a sub. Which would you prefer these two http://cgi.ebay.com/ws/eBayISAPI.dll...category=18804


these two http://cgi.ebay.com/ws/eBayISAPI.dll...category=18803

They are similar to the Kicker S12D and the Kicker S15C. I like the 15's the best, but I think the size of the box might be an issue. They recommend a 1.5 cu. ft. box, but I think that's a .9 Qtc. I think a .7 Qtc is about 5 cu. ft. box and .5 Qtc is 10 cu. ft. or 288 liter. I think I want a closed box although the 12 can go in a vented or closed.

Any suggestions? The 12 or 15 or neither? I thought about an isobaric design with the 15's, but it seems like such a waste, plus Kicker states that it's solobaric subs already behave like isobaric Kicker comp subs. I guess that's why they call them solobarics now that I think about it.
