X-over for single sided tweeter. - Click HERE for Original Thread
Jonathan Bright
I have a pair of small single sided tweeters. They are from a German Norde Mende "radio gram' bought in the mid '60s. They are around 60mm square and about 9mm thick. The frame is brown plastic and they have a circular bronze coloured metal grid covering the diaphram. I have a suitable circuit to drive them from an old "Audio" (USA) article. They were used in conjunction with an elliptical bass-mid that looks a lot like an Isophon unit.

What crossover frequency would they run at? Thanks Jonathan.

talking to the folks at Shackman as they deal with gear of that vintage.

Sorry that first post was confusing. I meant single sided ELECTROSTATICS as opposed to push-pull. Hope that makes more sense.
