Audio Nirvana Classic 12 and Classic 15: how new are these?
when I last checked my old stamped frame AN Super8's (just sitting), fs had climbed about a half octave - don't know if permanent or will drop again with use. That's in interesting approach to contain the angles with a built-in "horn".

[QUOTE=norman bates;4496561](without listening) I'd say so long as you don't mind losing a bit of dispersion, the "classic" should sound better (less ringing whizzer anyway). But I also know a whizzer (done right) can be made to bring down the climbing response of a cone driver.

I think someone here liked the classic 10 over the whizzered 10".

I think the super 8" cast frame has a climbing response that would require an equalizer, but listening off axis should smooth it right out.[/QUOTE


Question? Which speaker company has done the whizzer cone right on a full range driver? Where it brings down the climbing response of the cone driver? Mr. Jeff

You're welcome! Dunno, I mean I don't recall Symantec, Avast! [don't remember which I had back then], Malwarebytes giving me any warnings, etc..

Bud Purvine looked carefully at the AN15 and he liked the whizzer - said it was one of the best implementations he's ever seen. He compared the AN15 to an electrostatic - clearly he's a fan of this driver. I have one in an open backed box and find it performs well. Treble is not perfect of course, but boy there is very little compromise here given the wall of sound this driver produces when asked. And I'm driving it tonight with a 650mW Single Ended triode-wired pentode Spud amplifier.

Bigun, still 1 open backed speaker ?

I finally found what I'd meant about covering the backside of an open baffle with foam.

Right, this to me is how 'full-range' OBs should be damped when the baffle + room boundary isn't large enough to contain its BW to low enough for the rear wave to only damp the driver's Fs and/or when BW limited to the ~ mids in a multi-way.

One must be very careful with Audio Nirvana's published T/S parameters.
I have owned both the super 12 and super 8 stamped frame drivers, and besides the fact that they sounded dreadful (tried several enclosures and amps, including a high end SE EL34), the T/S parameters were all over the place.
David is very good at marketing his products but the quality and consistency at the time (some 4 years ago) was really lacking...
Never tried the horn ones though.
Let us know how they sound if you pull the trigger.
Regards,

I find that full range drivers need eq, always.
