Recently purchased four 808-8A horns for PA system. Two of the horns came with 809-8A cross/attenuaters. The other two came with, Wave Instruments, 1200 series cross/attenuaters. I know the 809-8A x-overs are at 800hz. I have no idea where these others cross, no test equipment. Anyone familiar with them? I am eventually going to active x-over, need these passive x-overs for now. Amazing horns. 600.00 canadian for four horns and two JBL 2220A which I am going to use in a set of wedges. My first post.
