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).
