I'm currently running a passive subwoofer on my surround channels, with my surround processor set to run the surround speakers as "large". I'd like to use this passive subwoofer (M&K Goliath) in my bedroom system where it is more urgently needed, but not at the expense of my main HT.Would the sound quality of my HT really suffer if I removed this M&K from the system and ran the surround speakers as "small" (80hz filter)?
I'm running some large 15" Tannoy Ardens as mains, a Radian coax as a center, and Klipsch KSF-S5s as surrounds. I use no other subwoofer, so all the front LF info is fed to the mains.
Follow Ups:
It is not the same without the sub for the very low frequencies. I once had some 12" Cheviots in my HT system, and they bloody rattled disturbingly on the very LF content. Whereas the sub gives more a feeling, and a certain amount of "sound" depending on how they're set up. A relatively small proportion of movies have significant LF effects, so all in all you wouldn't be missing much, but you'll suspect when the Ardens vibrate weirdly. To protect the Ardens, try a setup like "large" front speakers *with* a sub, XO frequency for sub lowest allowable, but don't actually connect a sub. Adjust XO freq upwards if it causes mechanical Arden vibration.[You'll note the Tannoy 12" and 15" HPD drivers have no difference in their fundamental resonance freq, and that's what causes the disturbing vibration at LF.]
