Ribbon midrange pros and cons

Dear @bdp24  : The only model in the Apogee catalog that goes below 1 ohm was the Scintilla and paired with the Classé DR 3-VHC ( 25 watts pure class A with over a headroom of 6dbs. A true horse/voltaje power. ) performs just great

I owned that amp and had for a while the Scintilla ( from a close friend distributor . ) as a demo pair.

Thanks @rauliruegas for that info. I think I’m one of the few planar loudspeaker lovers who never heard a pair of Apogees. For some reason they didn’t seem to be big on the West Coast; I never saw a pair in any California hi-fi shop, Northern or Southern.

Those are AMTs not ribbons.

The BG Neo planar midranges are real good, Philharmonic uses the Neo 8 in their tower speaker. http://www.philharmonicaudio.com/phil3.html

I also saw it being used in a speaker when I went to the Florida Audio Expo.

No clue on distortion, but it’s imaging/soundstage is excellent for the price, very glad that PS Audio is considering them, it looks like they are using the Fountek NeoCD3 for their tweeters, which is also a good choice, obviously not as good as say a RAAL 70-10D, but it is of course around 1/5 the price.

EDIT: Going off this image, it looks like the tower is using this Dayton tweeter, which is still efficient and has good imaging/soundstage, but I guess/hope it’s a placeholder and not the final choice, as it would be odd to use a different tweeter for the bookshelf and tower (you an see the bookshelf in the background with the Fountek tweeter). I also can only see the bookshelf woofer as being a KRK or HiVi one, as hardly anyone is making yellow woofers and I doubt Paul requested for the cone to be yellow.

ps audio looks like they are using the neo 10 in their speaker

I live just 40 miles from where Apogee was.
I suspect they were not prevalent on the west coast because they were very expensive to ship and very fragile which would have added a lot to the cost.
Scintillas destroyed more amplifiers than any other speaker I know of which interestingly enough made them a very popular cult item. They were ok but not near as sonically correct as the Divas. If you did not listen above 95 dB the Divas were fabulous. Their real talent was in the mid bass region. Upright acoustic basses were unbelievably real on these speakers. Only electrostats are capable of that kind of realism. Magnepans come very close. 
All planar dipole speakers have significant acoustic advantages over drivers in a box. The only place they stumble is in the very low bass. A subwoofer array fixes that,
