Please refrain from quoting the entire post just above yours. The quote button is handy, but resist the temptation to over use it! Thanks

(I've cleaned up the thread)

Got the x-over, it's a Nady CX-23SW 3-Way Stereo, Plus Subwoofer Crossover Nothing on the horns as yet. Really would like to talk via phone,lots to ask.

Piezo changes everything. IMO, it's not really worth it to bi-amp a speaker with a piezo HF driver. They just don't need any power and wouldn't benefit from it anyway. Input above 28V will kill them, and even short bursts won't give you any more sound. If you do bi-amp, only use something about 40 or 50 watts with your HF, and it will be loafing the whole time. Use about a 5 ohm resistor in *series* with it to keep the amp stable with the light capacitive load that they offer.

I'd just go ahead and screw on a real 1" exit compression driver, and cross at 1.6k-ish. The difference in dynamic capability will be night and day. A 50 watt amp may be enough, but use 100+ to have headroom. A light bulb limiter is a good idea unless you have RMS limiting capability ahead of your power amps, which you should set for an output voltage of 18V (40W, 8R)

Thanks for the reply Wg. I have put in proper drivers and the system is up and running and sounding sweet. A big thanks to Turk who helped me through this.
