Hi Austinbirdman
Interesting. SACD and DVD Audio are direct 2 or multichannel formats which bypass all the bass management functions of most receivers/processors. So, these high resolution formats deliver full range signals to the speakers, and would benefit from full range speakers in the front, center and surround positions. That would cost you as much as a house. THX is 'tuned' to an 80Hz cut off, very different from the high resolution music formats.
One answer is the Outlaw ICBM bass management unit. Results in many cables but bass management in high res format use. I have mine between an SACD player (separate cables for each channel in from the SACD player and separate cables for each channel from the ICBM into the processor. That friend, is a bunch of cables. BTW, the Outlaw ICBM also permits stereo subwoofer preouts.
Anyway, with the ICBM you can set the cut off frequency for each channel. It also gives you subwoofer and LFE output control. You have to pay a bloody fortune for a receiver or processor which will give you bass management while using SACD/DVD Audio formats.
With a well set up system with one or two well positioned subs, the lower frequencies will not sound like they're coming from the subs. It'll sound like your speakers are full range fellas.
