Jim gives sound advice. I'd also try to run the main system full spectrum, cut off your sub at the lowest possible x-over point and very carefully add a bit of sub as a third possibility. Reason: ALL X-overs, active or passive, degrade the sound on the high pass side, best noticeable in soundstage width and depth collapsing somewhat, more grain in the midband and a somewhat degraded high end. Cheers,
Sub Crossover vs. External Crossover
I am putting together a two-channel system, and I plan to incorporate a subwoofer for low-end. My mains are Tyler Acoustic Taylo Ref. Monitors, and my sub is a Revel B15. My question is whether I should use the crossover in the B15, or whether I should use a separate external crossover - I am concerned that by using the B15's crossover, I will negatively impact the quality of the signal going into my amp. My pre will likely be a Bryston BP 25 and my amp a Bryston 4B SST. If I purchase and external crossover, it will be the Bryston 10B (sub version, balanced). Any advice would be welcome.
