Midrange distortion on 15" PA driver

Distortion peak around 100Hz - 200Hz was due to screws holding driver in box being too lose. 😱

I have ordered B&C 8PE21 for midrange. I have read many good things about it.

BTW: Why was thread moved to "Live Sound > PA Systems"? This is HI-FI for a small room. 😀
 
I have finally finished them.

Distortion seems relatively low. I have more problems with furniture rattling in the room.

Crossed at ~400Hz to B&C 8PE21. Probably it would be even better to cross it lower, but I wanted passive crossover.

I have MTW configuration because otherwise tweeter is too high when I sit. Vertical dispersion is very limited.
