On a mission for more BASS

Would biamping Sophia 2's add a substantial amount of BASS (including SPL) from those 10" woofers?
What am I trying to achieve? I need more BASS from those 10's, and lots of it!
Streatch goal: Enough SPL to watch the crumbs on the coffee table bounce like corn in a hot-air popper!

The shop where I got the Sophia 2's demod the Sophia 3's and the BASS (especially in SPL) was very disappointing (or my expectations are too high for my $16,700 Sophia 2's).

Existing equipment:
3 McIntosh MC501 500W monoblocks
Pre-amp should have what I need as its a Tri-Amp (McIntosh C500t)
Audyssee MultiEq XT w/install kit (mic, software)
Sophia 2's

I'm looking for a 1000' view on "how to" or pointers for what to do for/to crossovers (removal/replacement/bypass/hack and so on).

Suggestions on how much wattage for each woofer (under breaking point) and how many McIntosh amps to leverage would be immensly helful. Was thinking about getting a McIntosh stereo amp for the mids and tweeters and then use existing MC501's to drive each 10 (or tri-amp).

2 ea. 10" woofers can only move so much air - if you really want to move enough air to

"watch the crumbs on the coffee table bounce like corn in a hot-air popper" there is only one way to do it. :-)

Or the next one up.

My own super biased opinion :-)

Good Listening

You'll need subs or another speaker. Check out JL Audio for a sub on par with Wilson speakers.

And you bought them anyway?

I tried bi-amping a couple of times with other speakers and the results weren't good because the 2 amps weren't balanced. So depending on which amp I put where, there was either too much bass or not enough. Of course my attempt was half hearted, and to do it properly you need active XOs, or at least the same amps top and bottom.
So I would say it is possible - If you can control the gain of the amps, just turn the amp on the woofers up more than the other amp. How that will sound I don't know, but I assume Wilson kinda knows what they are doing balance-wise when they design their speakers. But you might like it better, who knows.
