I'm taking a serious look at the 7" Excels in my own monitoring situation. I'm thinking MTM in a sealed box with a Qtc around .8 or so. At least, that's what I got out of Vance Dickason's book concerning what I want. I still need to investigate. It's going to be a big box. I haven't selected a tweeter yet.
I'm also seriously considering building a computer just to act as a DSP-based crossover system. It would make the system very flexible, and as an IT guy, it's within my comfort zone.
I have a small room, which I plan to treat quite liberally, so I intend to avoid all of that "digital room correction" stuff that comes along with computer-based crossovers.
Sorry for hijacking the thread.
