I'm tossing this out here not because I'm unhappy with my speakers, but because I'm hearing from people (including hardcore Klipsch fans) that the Belles with the AB Crossovers and the M-series drivers are dogcrap. I mean, the only deficiency I heard in these speakers when I first bought them was a gap in the 2k range, but that disappeared as soon as I switched from the cheap Sony stereo receiver to the Quicksilver Horn Monos. \n\nBut I've also seen measurements and what-not, a fair bit of evidence that, with some effort, these speakers could be better. There are companies dedicated to building upgraded crossovers and completely reconfigured drivers and such. \n\nSo what would you do, assuming you like the sound of horns (I know many don't), if you had an empty pair of Belle cabinets, to build the perfect speaker?
