Protium Posted September 4, 2008 Share Posted September 4, 2008 1. I want to wire a piezo tweeter into my practice cab (two 10" woofers in parallel), can I just wire it over one of the speakers and the cab will have the same overall impedance? AND 2. Does anyone know the minimum impedance cab you can connect to the speaker out on the Orange Crush 35B? Does this cut power to the internal speaker? Cheers!

jensenmann Posted September 4, 2008 Share Posted September 4, 2008 Don´t worry about the impedance. Piezo tweeters won´t do no harm impedancewise. But it might be too loud. Maybe you need a pot in front of the piezo to adjust it´s volume. Quote Link to comment Share on other sites More sharing options...
Protium Posted September 4, 2008 Author Share Posted September 4, 2008 Cheers mate, should it be wired parallel or in series with the woofer? Quote Link to comment Share on other sites More sharing options...
Dubs Posted September 4, 2008 Share Posted September 4, 2008 Just a thought – have you thought about crossovers? Quote Link to comment Share on other sites More sharing options...
Protium Posted September 4, 2008 Author Share Posted September 4, 2008 No, I don't think you need them for piezo tweeters. Quote Link to comment Share on other sites More sharing options...
Alien Posted September 4, 2008 Share Posted September 4, 2008 Impedance isn't an issue with piezos, but voltage is [b]very[/b] important. It's not a good idea to run a piezo at much over 25 volts, which is about 150W @ 4 Ohms, 75W @ 8 Ohms. If your cab runs more power than this, you'd be well advised to run 2 piezos in series, which allows a 4x increase in power handling. Piezos can sometimes cause oscillation in amps, so you'll want to put a resistor in series with the piezo(s) - something around 10 Ohm 10 Watt will do. Piezos should be wired in parallel with your woofers. Andy Quote Link to comment Share on other sites More sharing options...
