Bi-Amp Woofers with Class D?


I use an 25 watt class Integrated to run my rated 94 @ 6ohm speakers.
Recently I had a high powered class D amp in the system and it produced
better bass. 

Now I am debating bi-amping the speakers with Class D Monoblocks.
These seem to be available at prices under $2k.

Anyone tried this and what results did they experience?
Brands suggestions?

Thanks!

class D offers tons of power for not a lot of space and not a lot of dollars. 
pretty good for freq below 80 hz. And if you buy a class D amp to drive your woofers, go get a big one, not something intermediate....
Avanti,
Wish I could post a picture. I use an equilateral triangle arrangement overall.
The speakers in the FSMs consist of a 15" coaxial and a 15"woofer
in each unit. 
Is this your question?

Atma,
I am starting to think that rather than bi-amping I should consider
buying two REL T7 powered subs.

Any thoughts on that?

I don't bi-amp; my front speakers go flat down to 20Hz. I use the two subs to break up the standing waves in the room.
