Speakmeister Posted November 6, 2012 Share Posted November 6, 2012 Does anyone remember the schematic for the piezo crossover that uses an autoformer hooked up backwards to drive a piezo? I think it also had some type of network to smooth out the response. Please post it if you have it. Quote Link to comment Share on other sites More sharing options...
djk Posted November 6, 2012 Share Posted November 6, 2012 What speaker is it for? The network is best when customized for the speaker. Quote Link to comment Share on other sites More sharing options...

djk Posted November 7, 2012 Share Posted November 7, 2012 For the Motorola/CTS KSN1016A. 62Ω/2W series resistor on the tweeter. Connect tweeter with resistor to the 10W (62Ω) tap of a 25V line transformer. Connect a 6.8Ω/10W resistor in series with a 100µH inductor and place this combo in parallel with the 8Ω tap on the transformer. I used a 2µF and a .245µH inductor for the crossover driving the 8Ω tap on the transformer. This is easy with a type AA network, just jumper the last 2µF cap.

Speakmeister Posted November 7, 2012 Author Share Posted November 7, 2012 Thanks Dennis and Chris. That's just what I am looking for. Any idea where there may be old stock of the 1016? I found a website that claims to sell some made in the Philippines, but not sure if those are good or not. Quote Link to comment Share on other sites More sharing options...
