Thanks. I think the Behringer NU3000DSP is the way I will go, but how is fan noise? This is in the media room and only used for movies. I'm just wondering if buying a new subwoofer for around $400 is a better option if there's a decent one at that range.They may be able to repair the amp, too. External amp is as easy as running speaker wire from amp to driver, how you do that can vary.
