Thanks guys, they "sound" impressive.

St_PatGuy, the bass hump shouldn't bother me either, as I like a slightly forward sound. I graphed your frequency response measurements in Excel, and they jive very nicely with the NRC graph - nice going.

I won't be getting your nice walnut finish though \:\(
