Do these speakers exist?

Thanks for the replies.

1) The Green Mountain speakers are absolutely killer. The C3 is quite a stretch for me at $17K and the Calypso is 88dB sensitive and 4ohms. Likely marginal with SET.

2) I used to have Gallo Ref 3s. They are 88dB and just don't cut it with 20W SETs in my experience.

3) I should have said no ribbons. Dynamic speakers only. No ribbons, no horns. I'd never heard an example of either that sounds SOTA for me.

Thanks again.

If you think 90dB speakers can't work well with higher power, 845 and up SETs, your experience isn't broad enough.

What you note about Thiels is apparantly NOT true of the new 3.7. They are supposed to be a much easier load. I don't know for sure.

I had always thought 1st order xovers were the EASIEST load for an amp. They are the simplest crossover - fewest parts - least loss of energy. I have read this many times, but perhaps it is wrong.

Duke, you're absolutely right! Except that I already have a pair of Consonance Cyber 845 monos that I really, really like and just don't want to part with.

I really am into SET... I have been through zillions of amps and want to stick with SET. There are more powerful sets than these 845 monos but they are either much more expensive or don't sound as good or both.

You are quiet right that they may well drive a 4Ohm load with no problems. You may be right. All the GM speakers are VERY flat impedance, too. It was the 88dB sensitivity that is of more concern... requiring nearly double power for same SPL. My room is completely open.. the numbers are marginal there.

Also, I've not heard the. The C3s "blew me away". If they weren't $17K... not that I need any new speakers at all.. this is perhaps only a long-term planning thing. Would you believe I bought new (demo) Hyperion 938s less than 6 months ago? Am I pathetic, or what?!

We really do need an audioholics anonymous.. for real. :-}

The Vandersteens are just a bit off on the sensitivity. 87 is not high enough. Not in an open room. I'll have to try to hear these speakers, though. Never heard them.

Is the question stupid? Forget about 845 SETs if you want speakers like this? Yes, well, maybe at least one of these "requirements" has to give. That may be the way it is. That's why I asked.

A bit more on single-drivers: in my experience they can sound quite good but, again, just not "SOTA". The GM C3s blew me away and meet all the criteria *except* price. The Thiel 3.7s did too but not to quite the same extent. And it may be true that those will not do well with 20-30W either.

$5K? For the current version? Hard to believe.

Roy is such a great guy to deal with, such an asset to the industry, and has taken so much time to answer questions, I'd honestly feel a bit guilty about buying them used. Maybe that's stupid. I suppose that's better than buying something else or not buying anything! Actually that latter idea is the best one...

I had forgotten all about VPRS. A lot of people sure love them. Never heard those either. Geneally I have to either drive for hours or go to a show to hear stuff. They are sensitive, too.

I went thru the archives here including a loooong thread about t&P dominated by Roy of GM. Boy, that man is a genius.

Yeah, agree on that. Find that old thread circa '02-'03 and you'll be even more impressed. He has an answer for everything... not a marketing/BS/subjective/questionable answer but a real, thorough, detailed answer backed-up with physics and acoustics in layman's terms.
