....from Dennis Had?
Follow Ups:
They don't look like high efficiency to me... small drivers with small magnets on small open baffles rarely are.
I also remain unconvinced that High Q drivers are suitable for amps with high-ish output impedance (ie. zero feedback amps).
Cheers.

here is the link below! these are high Qts and Qes woofers.
What does Dennis say about them? I'm driving Klipsch Heresy III's with a Decware Mini Torri 6V6 amp, about 5 watts, and the combo sounds very good.
Dennis hasn't said anything about them, maybe he's not ready to release them yet. He sent me a few photos of them, but when I tried asking for more info, he just went back to talking about his Inspire amps. I've seen he is selling Inspire amps and preamps on Ebay. There is word that he is coming out with a Inspire phono preamp this summer. I haven't heard any word at all about Inspire speakers, just a few teasing photos.
Since Dennis wasn't answering my questions, I thought someone here may know Dennis better than I do and have some more information.
"What does Dennis say about them? I'm driving Klipsch Heresy III's with a Decware Mini Torri 6V6 amp, about 5 watts, and the combo sounds very good."
As good as they may sound with a low watt amp they sound even better with a no watt amp.
Have you even heard the Heresy III?
I thought not.
The Heresy II and II are a vastly different speaker than the old Heresy you love to hate.
"Have you even heard the Heresy III?"
Yeah, I did hear them, when Saturday Audio in Chicago sold them. I was curious about a speaker that claimed deeper bass AND higher efficiency than the earlier models that used the same size closed box. True, they weren't as bad as earlier models. IMO.
H3's are more efficient 99db1w1m(just saw djk note 94) and the tweeter was changed to tractrix. Great sounding little speaker. At least it isn't covered with magic pebbles. lol
I must admit to being confused by open baffle speakers. I've heard a few at LSAF but they didn't do much for me. I assumed the attraction was similar to single driver solutions being simplicity of build.
High sensitivity, wide dynamic range, low distortion, and smooth frequency response. Pwk

> I'm driving Klipsch Heresy III's with a Decware Mini Torri 6V6 amp, about 5 watts,
Sure, but Heresy's have 98dB sensitivity.
Klipsch now adds 3dB~4dB of 'room gain' to the actual efficiency.
> Klipsch now adds 3dB~4dB of 'room gain' to the actual efficiency.
More than that with all of their current stuff. 98dB for the Heresy isn't an outrageous claim, though they're now saying 99. 101dB for the RF7 is silly, even with an extra 4dB for room gain, which must be posted in such fine print that no one can actually see it.
OB and high efficiency tend to be mutually exclusive, as do high Qes drivers and high sensitivity, and those smallish magnets probably indicate a pretty high Qes, which one would expect with an OB.
"OB and high efficiency tend to be mutually exclusive"
Does 97dB/1w/1m qualify?
You are right Bill, I just found out that these speakers are only 90 dB efficiency.
You're right. To get decent bass open baffle need 12DB/octave equalization for at least a couple of octaves and that's a ton of power.
By the way the tweeters look like unobtanium, Dynaudio(D21 or D28) from the 80s or early 90s. I haven't seen them in ages.

I'm sorry, perhaps this post is misplaced. Obviously I am not a speaker designer.
I just assumed that since Dennis Had's new Inspire amps were 5-12 watt single ended tube amps, with his personal favorite being the 5 watt 6V6 design that his new Inspire speakers would be a high sensitivity design.
I do know what they say about assuming though.....
Check out the Yield at Fastlane Audio, it's more efficient.
