KLH model 9 electrostatic Speakers

Ralph thank you for your response, I checked the zeroimpedance unit $1149 a pair. 

Ralph it looks like my Art Audio concierto 40 w will be benefited from the Zero impedance, I think the KLH need to be using 16 ohm.Thanks again...

Ralph, why not just put 200 watt 2 ohm resistors in series with the speaker. Yes, they would absorb some power but they would cost only $40 dollars and I bet you would still get 60 Watts out of the M60's. The other thing is the roll off would be way up there and I doubt most of us could hear it?

Will Dynaco st 70 watt good enough power for the nines?

It will run them. But the amp, as good (as a refurbished one is) will be a bit outclassed.

You can hear it. Its an interesting idea; if the power isn't an issue it might work.
