In Reply to: Recommendation below is only one possible option, and not necessarily optimal... posted by carcass93 on March 27, 2007 at 08:14:48:
Hooking the sub up to your pre out and still giving your main speakers the full range signal will be a nightmare to setup, if not impossible.You absolutley need to have your main speakers crossed over in some way. The sub's crossover, on it's own, no matter how well designed, is not going to match your main speaker's falloff curve.
So... either use the crossover built in the sub to connect your mains to (recommended), or have a receiver with one built in that has an LFE out (your NAD, of course, does not have that)... and the only other way is to connect the sub to pre-out number two, and place a passive crossover between pre-1 and the amp in and then match the crossover points that way. If you want to go the route of external passive crossover, let me know and I can post a link to the place that sells them.
