Mine are now pretty much done. I say pretty much because I have a horn lens substitution sitting on top of the box and some CH3 sized MDF pieces mounted on the cabinet face to keep the air in. (and don't you know how much air is moving in there) I should have real live CH3's next week and then I will post some pictures. I have had the components for four days and while waiting for horns and have been running them while I go to work so they relax a bit. I decided to mount the compression driver to some old 800Hz mid horns to see what would happen. Wow! these really do sound good even with the long throw mid horn. I cannot wait to hear them without the sniper rifle presentation and weird top octave peaks of the long throw horn. I am hyped. I don't even know what I am in for with the right horn and I can already say that Wayne is a relatively modest man. Thanks Wayne (and those who have posted all of these great informational nuggets here. I am sure it helped make my ride a lot smoother)

with the 4 Pi Pro's, effortless power and dynamics. Un-rack mounted, ie sitting on a shelf, it's dead quiet with your ear to the woofer, a slight sshhh from the tweets. Not sure how common the problem is, but mine had lost "bass extension" on just one channel. Replaced the electrolytic cap in the feedback loops, and the problem was solved. Thomas, if you own a DMM, be sure to verify the output device bias settings, adcom bias pots are really inadequate, now that I've had her opened up, I'm ordering "multi-turn" replacement units soon.
