Guys,
I found this thread over at AVS forum:
http://www.avsforum.com/avs-vb/showthread.php?s=39c3c77292dbf118ad49baeb8d2619f3&t=687600It's a long one, but some people seemed to have this discussion 2 years ago. It's a very interesting read, and the founder and CTO of Audessey Labs even posts to clear some stuff up!
Two of his quotes (this is from the man himself):
"The simple solution is to make the bass management mode (under Subwoofer mode in the setup menu) to be "LFE+Main". In retrospect, I believe this should be the default mode for the receiver, but in any case this is a simple thing to check. Putting the system in this mode allows "Large" speakers to be bass managed at the crossover frequency found by MultEQ (you can see what this is in the crossover set up menu once you switch to LFE+Main."
and:
"The simplest way to think of it is: Large will not be bass managed and Small will. If you ar lucky to have a true Large speaker that has a –3 dB cutoff of 20 Hz then this is not a problem. If you don't then you have to make sure that the bass below the actual cutoff is sent to the subwoofer. That can only happen if you set the subwoofer mode to LFE+Main.
LFE+Main will send bass to the sub and the mains as you say. This is not as bad as you think because the main speakers are actually crossed over to the sub at the frequency that was determined to be optimal. For example, if that happens to be 60 Hz, then anything below that goes to the sub and anything above it goes to the satellites (even if they were found to be Large)."
