Be careful with the horns
Granted I have an older set of thes units so Peavey may have corrected the issue but I have the 14XT horns just like these and I have blown both the fuses and the voicecoils of these horns. The LF drivers seem to be able to handle the 500 Watts I send them but the horns can't keep up and I blow them. I have gone to JBL JRX125s on the same amp and they seem quite happy and give me the HF that I like to hear. In both situations 150Hz (xover point) and below go to Yamaha S118s. I think as long as you don't push them too hard they will be OK.
