Thanks for the reco's guys! Sounds like it'll be worth my while to make the road-trip to the next Tweeter, Etc to listen to the JLs and Focals and whatever else they have there. (The two Tweeters near me closed a couple of months ago!)

I used to have MBQuarts and loved them, but you really have to dump power into them to hit their sweet spot. I never cared for that signature sound of BA's. I've never heard of Digital Designs or Diamond Audio, but will try to track them down as well.

I am leaning more and more toward amping though, but I have to check on a couple of options for storing the spare first.

I'm still listening in case anyone has anything else to suggest!
