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).

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.

Bi-amp won't do it. You need big subs.

Be careful, don't overdrive those 10" woofers in your Sophia, they are expensive to replace.

It really is more dependent on the size of your listening room. For really big bass, you need a BIG room.

Not sure why you would buy a pair of speakers with "dissapointing" bass but that is another issue. Forget bi-amping. You don;t need big subs - for integration with the Sophias yoou need fast subs. Get two JL Audio 113's. Additional benefit is you can run the subs through a bass EQ unit.
