(Also posted at avs). For some time now I've been thinking of trying out my X-30 crossover as something more than just a convenient volume control for the subwoofer. My current set-up is as follows: Yamaha RX-V3000 receiver, all speakers set to small (90 Hz Xover) Bass/LFE out to X-30 to Paradigm Servo/15 Paradigm Reference Studio 60s, ADPs and CC. Proposed set-up: Sub set to no, mains to large, all others to small. Main pre-outs to X-30 (80Hz Xover terminals), high pass back to receiver main-ins, low pass to sub. The benefits I would expect might be: - Now have bass management for DVD-Audio for at least the main channels. Great for two channel DVD-A mixes, and at least some improvement for five and six channel DVD-A mixes. - The crossover frequency is lowered to 80Hz. The drawbacks would be, I think: - Analogue bass management is inferior to digital bass management. - Center and surround material is now crossed over twice, 90Hz digital crossover in the receiver followed by 80Hz analogue crossover in the X-30. Could be ugly. - Discrete LFE >80 Hz intended for the sub is redirected to the mains. - Unclear what happens to the LFE channel from the RP91 six channel out, since the RP91 has no bass management for DVD-Audio (I think this means losing it if there is no sub) and the receiver has no bass management on the six channel in (again I think this means losing it if there is no sub). This could be the show stopper. I guess could just try it and see what happens, but that would mean buying four more interconnects and rehooking everything. I thought I'd post first and see if anyone has experimented with something like this. Also I know that there are folks on this forum who understand bass management a lot better than I do who might validate (or invalidate) my assumptions and offer their comments/suggestions.
