Janszen Z-960 Info?

sheep · 26th November 2012, 12:41 AM

I have acquired tweeter parts to a Janszen Z-960.
These have 3 electrostatic panels.
Would anyone have a schematic diagram of the crossover?

What are the thoughts on the sound quality of the 130 drivers?

I tested mine and they do go below 1kHz maybe 700Hz.
The hard part is to find a woofer and box that can match their transparency.

Well ....yea...
I had these funky ...balls that had 6" drivers in them...This was in the 90s...the balls sounded great an had some of the best bass output i have ever got out of a 6" driver....Down to 40hz ezey..People freak out when that saw what thay were.... thay were eze to match....
you Can see the 130 had that pot on the AC coming in so you could set the output by lowing the bias......this is a great way to mach the out put of the panels to the bass drivers...it drops the bias an the littel ESLs still putout great sound ....
I use that same setup on my Acoustats.Bias..an lets me go from 4-7k...eze to setup an work like a charm....good luck

Are there dust covers like the Quad ESL-57 cause I don't see any.
Seems very efficient, though the crossover is very simple.

No it look like list wire to me....yes lowsh SPL for sure...i pumpet up the bias some..it been some time...last i had going was 4ea an 10" bass in each speaker... it worket...i have about 6 pr of MLesl here an my Acoustat, an magnepans ...Apogee ribbons..lot in flux.. i think i ran the janeZan..at about 5k up.... I only saw them as Add on to a pr speakers..... best sound i got was 3ea with no back all open...one on top of the other..if ea.panel is 4"x3" thay would have been 12"X.3.....have fun
