Goldwood GT-1005 Wide Dispersion Piezo Tweeter
I have 8 ohm speaker and I want to hook up GT-1005 Piezo tweeter part # 270-011 with it in parallel what capacitor should I use and do I need to add a resistor in series so I will have at least 4 ohms?

Can i crossover these at 3000HZ ?

how ohms is this tweeter?
Being a piezo tweeter this does not have an impedance.

I am trying to use these tweeters to emit a constant tone from a tone generator. I'm trying to get as much volume as I can.I'm using an Onkyo SR701 receiver to power them.I was told to put a 4 ohm or 10 ohm 10watt resister parallel across the posts of the speakers.The protection circuit in the Receiver kicks in with the volume at about 80%. I want to go louder.Also, the resistor gets very hot.I was told I'm wasting energy by using a resistor and I should just use different tweeters. I'm not experienced enough to know if that is true.Should I try different resistors? Or would I get better volume out of some 8 ohm tweeters? I'm trying to keep this as low cost as possible. What do you guys think?Use different tweeters? Which ones? Would like to keep total cost under $10 per speaker or tweeter+resistor.
3.3 uf non polar cap to feed 10 ohm non inductive and 2 0hm resistor... then 10 ohm to ground and the 2 0hm to + of the horn an additional 20 watt 20 ohm to soak up the residual power and load the amp... a siren type amp may better serve you along with a larger voice coil type horn,, i see burned parts in this project with out knowing all paramerers

Is this an 8 ohm tweeter?
Piezo tweeters do not have impedance loads.

How would I attenuate this tweeter to match db level of Visaton 6.5" Woofer 4Ohm (part #292-566). The drivers are in a .71 cubic foot enclosure with full signal going to the tweeter and lpf at 3700 going to 6.5" driver. Right now I have no filter going to visaton, so it's full signal going to both drivers and they sound good together there is just an overlap of signal 3700 and up to top range of 6.5" driver. When I add the lpf at 3700 to visaton the tweeter becomes more (too) noticable and doesn't blend as well. How would I attenuate the tweeter to match the other driver in this setup?
You will have to put an 8 ohm resistor in parallel with the piezo and wire an L-Pad in line with it. Please see the diagram.
