Dan,
If you are parting with your big speakers, that is a ringing endorsement of the new speakers. Yes, the DIY aspect makes them even sweeter, and for those of us without woodworking skills, the locking system is a big help. I love my Blumensteins, but gotta believe that two front-facing drivers can move some air. On a bit of a side note, I'm starting to think about getting another Stereomour II and running one per speaker. In the real world, how much more headroom does that get me. And do two Stereomour II's strapped with the shunt mods match one Kaiju for ultimate sound quality? And since I'm swinging for the fences, would the BeePre take it even further?
Oh yeah, Happy Memorial Day everyone and giving thanks to those you gave the ultimate sacrifice so that all of us can spend our time able to fixate on our crazy hobby....
