Active Crossover Recommendations

marchand crossover doesn't work. I wasted time and money on those (still waiting for refund). Be careful!

Linkoping...Please provide some detail about your problem with the Marchand X/O. They have a reputation of excellent performance at reasonable cost, although my experience has only been with the SS units.

It may seem cheap, but there are a lot of positve reports on using Behringer DCX2496.

It's not the price of the Berhinger that puts me off, but the fact that it appears to digitally upsample and then downsample to do its crossing over. I can't imagine that would be good for the signal, even at 24/96. Kenn39 - what have you heard about its application?

I purchased a used Bryston 10b-sub, and will give that a shot. The distribution of frequencies that they chose is not all that suitable to my desired 120hz Xover frequency: they use:

50, 60, 70, 80, 90, 100, 200, 250, 300, 400, 500.

Bryston will change out the resistors at a cost. I will play around with the available frequencies, but think I may modify it to:

70, 80, 90, 100, 110, 115, 120, 130, 140, 160, 200, 250

The rolloff slopes are choosable b/t 6, 12 an 18 db/octave. It may be worthwhile to leave a gap between high pass and low pass, and I'm not sure how big of a gap, that's why I'm thinking of using high resolution around 115 hz, my target area. Any thoughts or suggestions?

Thanks, Peter S.
wouldn't ever do that to my signal, although it is probably very effective frequency wise.

Peter, I first read about the Behringer on the Newform Research Speakers website: http://www.newformresearch.com/digital-systems-overview.htm

There are many posts on various forums by people who use it to do bi-amping.

The Behringer does not resample. It does A/D and D/A to do the processing in digital domain. The conversions may be a concern. The digital domain processing provides a vast array of options though.
