I asked a similar question earlier...
I'm about to purchase a Denon 4311ci.
My front speakers are VMPS Super Towers which each contain a 12" and 15" woofer. They are extremely efficient speakers as well. These speakers are biamplifiable using the speakers internal passive crossovers. Crossover is at 80Hz. I do not plan on getting a subwoofer.
I've posed these questions on the AVS forums, but still a little confused.
1. If I understand correctly, given that XT32 has 512x filter bands for each channel usable across the whole frequency spectrum, is it a theoretical disadvantage to have these bands distributed across the whole full range of my front speakers vs. getting a separate amp and running it from the sub pre outs of the receiver to the woofer section of the VMPS speakers? Would I then have 512x points available for correction to the woofers, and another 512x points available to the mid and high freq section of the speakers?
2. If so, can I accomplish this same thing by using the rear surround channels to power the woofer section instead (biamping, but using the extra Denon channels that I wouldn't be using anyway).
Thanks for your help.
