1979 Janszen Z-600 panels for DIY center speaker?

rkellyfitz · 7th November 2009, 09:06 AM

I'm looking at buying these 2 Janszen Z-600 panels to use in a DIY center speaker: 1979 Janszen Z-600 Electrostatic Panel Speakers (PAIR) - eBay (item 150385941062 end time Nov-08-09 12:52:48 PST)

--What is the frequency response of these panels, and what should the crossover frequency be?

--Do these look like they function OK?

--Would they work well for a DIY center speaker?

Don't these need power supplies?
My feeling is there are better small ESL sections around that are better value for money and also more likely to still have some functioning parts (like the old Realistic(?) things). But I'd be glad to also know of more options, as I am also thinking along the same lines (of making a custom center channel from ESL sections).

Yes, you would need a high-voltage power supply for the diaphragm and also step-up transformers for the stators, none of which are included with these Janszen panels.

The hard part is to get the specs for these panels, to know the right voltages for the diaphragm and stators, and also what the frequency response is so you can set the crossover.
