Odd to me piezo tweeter wiring originally posted by wolf view post pe and darren always advocated in ad copy the use of a 22 ohm in series to preclude burnout fwiw and this actually set the xover point for the piezo being it was a capacitive unit. Ok not quite in the same way as a compression driver but more in the manner of limiting the voltage that arrives at the terminals.

Piezo tweeter wiring diagram. This is the setup that many first time cbg builders use when looking to be able to plug their build into an amp. This somewhat damps down a harsh resonance around the lowest frequencies that piezo tweeters work at. A single piezo transducer wired directly to a mono two pole jack. Rat shack and la sound come to mind. Odd to me piezo tweeter wiring this was actually a very popular wiring scheme for many of the car audio enclosures using piezos in the 80s and 90s. The switch causes a popping sound when switching to piezo because of the impedance mismatch so a blend knob would be well suited to add the piezo to the pickups and turn down the pickups volume for piezo only.

This diagram shows about the most basic wiring setup you can get.
Wiring diagram for d4120 to apa151. Ive used the same wiring scheme myself simply because if the tweeter did blow it would not create an amp damaging direct short. Reverse polarity from the woofer. Many builders stick with this basic setup and never feel the. Sure enough thats just what i found inside. The trick is to solder thin pieces of wire to the ceramic piezo element leads.
