Well, after building my IB manifold (and waiting patiently for the room it'll be installed in to be finished ) I was thinking... I've read time and time again that mass-built speaker boxes impart colorations into the midrange because of their poor bracing and build quality. And then I saw Parts Express' pre-built boxes and got an idea. My speakers are bipolar, so I have two midranges and 2 tweeters. What if I used those two midranges and one tweeter on an MTM configuration? Would I realize any sonic benefits? I took a long look at my current boxes. They aren't braced at all, and if I give them the "knuckle rap" test, they sound hollow, thin, and with lots of resonance. Opinions?
