Jim,
Thanks for the comments! Yep the room is soundproofed very very well. I can listen at any volume I want any time without bothering anyone else in the house.

My dad, brothers-in-law and I built the room from scratch. I built the SET amps too. Very happy and proud of this whole system as I have modified every piece of gear I own except for the Bolder Modded squeezebox and the woofer amp.
Any way, sorry to go OT, but to bring it back full circle a modified dcx is a phenomenal way to go active. The problem with hand building an active crossover is being able to adjust for bass issues, driver anomalies and other nasty stuff that really must be dialed into submission. This is one of the biggest (if not the single biggest reason) to go active.
