Choosing Sub-woofers. Please advise ASAP.

Finally, I have committed to the new home theater system and need sub-woofers. My listening and theater space is about 16' x 14' but then total open space (kitchen in the back) is 16' x 32'. I would like to listen to non-dealer advise. Thank you.

I like the REL and the JL Audio but JL Audio is my primary choice. The question is 2 x 12" or 2 x 10" or single Dual 12"? The stereo dealer told me 10" would blend in better with music while HT dealer says 12" will have better effect because even my listening space is mall but overall room is large.

Your thought please? I need decision by tomorrow so I can close the final piece. Thank you.
