Good interview, enjoyed that!
I used mine at rehearsal last night and the PRRI really has no trouble with a loud drummer now. It is definitely a not too colouring speaker as Jeff says. The highs are very smooth, a bit like the Crex. There's no breakup or sizzle you get from some speakers but I like the smoothness with the Blackface cleans. You definitely hear more amp than speaker but it does add it's own pleasant subtle thing.
Can't wait until it breaks in!
