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.

Mcintosh MX160
Mcintosh MC1.2Kw x 2
Mcintosh MC205 x 2
Wilson Audio Alexia - Front Left and Right Speakers
Wilson Audio Mezzo - Center Speaker
Wilson Audio Sophia - Side and Rear Surround Sound Speakers
Origin Acoustic D88 - Atmos Speakers

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.

Driver must move at frequency to reproduce however smaller drivers have to move more i.e. At greater amplitude to deliver same SPL. as larger driver else you need multiple drivers.  
I actually bought a pair of JL Audio E-Sub E110. Originally I was looking for decent HT system and saw this pair of brand new at great deal, so I got them. Then it seems like the more dealers I see, the bigger the system gets. Now, I also wonder if e-sub is enough to match the Wilson? I tripled my original budget so..... trying to save now!

arghhhhhhhhhhh......
" If you want to make bass, you can either move a large driver slow or a small driver fast. If all other factors are equal, there'a no difference. "

" That doesn't make any sense. A driver's movement corresponds to the frequency it's asked to reproduce. If it's a pure 32 Hz tone, the cone will move at 32 cycles per second, regardless of the cone's diameter. "

That's not true. The lower the frequency, the more air you need to move. If you make an 8in speaker move the same amount of air as a 10in speaker, then you get the same frequency. That means the 8in speaker has to move faster than the 10in speaker. 

Check the specs on some speakers. Quite often you'll see speakers with smaller drivers that can go just as low as speakers using larger drivers. A good starting point would be to have a look at Carvers Sunfire Sub. He does a way better job of explaining this than I do.
