Yep, they's up and running. I've got them hooked up to a hifi amp for running in. They work rather well, not quite up to hifi standard, but very presentable for PA work. Still have to tweak the x-o a bit, it sounds best if I put some bass and treble cut on the amp, so i guess I have a midrange dip in the speaker. should be easy to fix, calculated x-os are never spot on first up !Thanks Wayne for the Pi-align specs, and Paul C for the x-o diagrams, I'm actually crossing higher, about 2400, (mainly cos I wanted to use what I had available rather than buy new coils etc)
