I am parting out 2 pairs of Kings Kingsound electrostatic speakers circa 2009. I had planned on rebuilding them into a slimmer and more spacious frame as the original had the HV wires crammed into to small a space causing breaks and arcing. With Covid, listening opportunities and space have changed and I have decided that I don't have the energy to keep working on these. I am willing to sell separately but obviously would like to clear the lot. I don’t have the frames any more.
The thread I started when I bought them is here. Kingsound King electrostatic Unfortunately I have lost the original pictures.
I had 2 pairs of very similar model Kingsound KS3000 speakers.
Each speaker comprises of 1 pair of Step up transformers, 7 bass panels and 5 tweeter panels.
I measured the transformers with a 1000 Hz tone to check the step up ratio. The crossover is meant to be set at 1000 Hz or so but I used a minidsp 4x10 most of the time. There are seperate HV PS for the bass and tweeter. Bass is 6.5v and tweeter 2.6 v. I have a few spare sets with slightly lower bass voltages. I have modified one pair with a variable DC input voltage.
LF transformer 1: 150
HF transformer 1:75
2 pairs of HV power supplies, 6.5Kv and 2.6kV.
7 bass panels per speaker – 431x221x10mm, The stators alone measure 405x195x1.6mm. DS is 2.5mm. All in working condition. One of my plans was to make my own frames for the woofer panels.
5 tweeter panels per speaker – 300x139x8mm. Stators are slightly smaller. I think the DS is 1.5 from memory. 1 pair is in good working condition but the second pair has a small hole in one of the diaphragms. Doesn’t seem to effect it as they were like that when I got it. A bonus is that in addition to the above, I have a new and unused in original box, set of 10 tweeter panels.
Crossover set at 1000 Hz. Note there are no Inductors involved. I used steep crossovers at 1000 Hz. One pair is bi-ampable and one single input.
There are around 10 bass panels as well where some have holes in the diaphragm or broken wires and a couple are good.
Prices: I expect A$ 300 for a set of step up transformers. Ie 2x HF and 2xLF transformers. A$ 200 for the new set of tweeter panels. Open to offers for the rest.
for reference I have included pictures of the original speakers.

The "new and unused in original box, set of 10 tweeter panels" have sold. The rest is still available.
