only problem is calculating the angle of curve, anyone got an idea, probly be building the curved but out of layers of bendy hardboard, and the box out of spare 13 lam ply

theese will be arrayed horizontally rather tahn vertically as with the system as it is some of the venues we use simply don't have the height

Hi,
I'm going to built some piezo array vertically stacked. In these arrays I want to put a compression driver to protect my amp ;D.
So I have some choices...
a. Straight baffle, compression driver on top
b. Straight baffle, compression driver in the center
c. Curved concave baffle, compression driver in the center
d. Curved convex baffle, compression driver in the center
e. Curved concave baffle, compression driver on top
f. Straight baffle, recessed a little on bottom to fire over the crowd, compression driver on top.

ah.. I just ordered a bunch of piezos myself. I have seen a lot of modification to these to try and make them sound good. I want to put six in a box and hook them to my mids with no crossover ( :o ). Any suggestions on wiring or resistors/ caps. I can't get 50 ohm 20 w resistors like most people suggest. seems like evrywhere i call, they still have to dig up the material and assemble them somewhere in china
