Thanks, Doc. All finished!
I've got the Stereomour II on tweeter duty for now. I think I like it better this way. It seems like the highs are more detailed (I heard parts in Talking Heads' Slippery People that I'd never heard before, and that's my test track for any new piece of equipment), and the bass feels more weighty. It's entirely too early to tell for sure.
Overall I'm very pleased with the sound. I'm not over the moon with the finishing job I did, but that's on me.
