Hi Brian-

For the record, I can get about 35-40 manufacturers at dealer cost, and sell about $25,000 a year in products—from amps to raw drivers to processors. I am not a dealer in the true sense of the word (I have another very time consuming job), I just have a number of good audio friends that help me out from time to time.

I use an MC-1 for my system, but there will be no difference between that and the DC-2 when it comes to using EQ’s.

I use DBX 2231 EQ’s. They are professional analog EQ’s that utilize the DBX Type III noise reduction system that works amazing wonders—even reduces buzzes and noises quite well if you have buzzes and noises in your system. These EQ’s are unbelievably quiet. Anyway, I use a total of four of the 2231’s (2 channels each) so every speaker has individual control. Since every room is different, and there is no such thing as an anachoic chamber for a home theater (at least I have never read/seen one), they will really help you dial a room into perfection—provided you have the right analysis equipment. It would greatly help you (should you decided to get a 1/3rd octave EQ) if you had some sort of RTA (real time analysis) program with a flat frequency response microphone or you may make your room sound a whole lot worse with an EQ. I personally use the JBL SMAART real time analysis program with an Earthworks M-30 flat microphone. I am VERY pleased with the results.

You can check out the 2231 at www.dbxpro.com They retail for around $600.00 each.

A much less expensive way to dial a room in is to use some sort of absorption and/or diffusion paneling. This helps to eliminate room low frequency resonances, reduce the RT60 time of the room, and allow the speakers to have much greater control of what you hear - instead of the room controlling what you hear. No amount of EQ can do all this as well as some real good absorption/diffusion solutions.

I personally think that utilizing both absorption/diffusion solutions in conjunction with EQ is the best situation, but you may get as much improvement as you need with just the absorption/diffusion stuff.

Chuck
