Goldwood GT-400CD Bullet Piezo Horn Driver
What capacitor and resistor would I need for a 2nd order crossover (3000-2.5k) for this piezo?? It will be paired with a Dayton Audio PA310-8 12". Thanks
This is the horn driver I need but I would like one with more power than this one. I bought to of these before and they both have went completely out.
Unfortunately the highest powered piezo horn driver we have is 100 watts RMS.

Does this driver have the protection circuit that the original 1142 has (PZT and light bulb)?
This does not have the protection circuit that was on the original power line piezos

Hi guys, will this piezo tweeter screw into the back of an eminence Beta 10-cx coax driver and no cross over ?
Yes this will screw into the back of the Beta Cx models and a crossover is not required.

100W of "highs" or overall wattage?
HiI am a bit confused by piezos and their wattage. If I put 500 watts into a 2x15 with a real crossover and a real horn, the voltage going to the horn is only a very small portion if the 500 watts.Is this how it works with piezos? Or if I put the same 500 watts into a cabinet with a piezo described as 60 or 100 watts or whatever, would that immediately burn out the tweeter? or does it only "see" the small portion of the signal over 2k (or whatever the crossover point is supposed to be). This would make a 100-watt piezo pretty happy in a 500-watt cabinet I would think. 1800 Hz is too low; 3K would be better for me, but I want a lens-mounted one. Would a cap of (value X) help?Thanks
Actually, most piezos are employed without a crossover and receive a full signal. That's partly the reason for their use in low and mid quality speaker cabs, they save money. They have no motor structure like normal drivers do. Basically the published wattage handling is for their overall frequency range. They are rated for 100 watts (rms) input over their stated 1800-30000 Hz frequency range. I have used them in my PA cabs, without a crossover, and powered by a Crown MA-5000i class I amp and they received a full signal with no problems whatsoever. You can, however, use them with a crossover if your cab already has them installed. Probably the best bang for the buck piezo out there.

what is the drivers max wattage
The manufacture does not specify a max wattage for this driver, however you can figure double RMS. Max wattage is basically irrelevent, you don't want to put any more than RMS into a given driver.
