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.

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.

Well, the frequency (i.e., the period between when the derivative is 0) won’t change based on driver size but cone velocity will, for a given output.
The "cone velocity" is the driver's frequency. If asked to produce a 32 Hz tone, the cone should move at 32 cycles per second, regardless of the diameter of the cone. It's simply not true that:
If you want to make bass, you can either move a large driver slow or a small driver fast.

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.
