Not manufactured any more.

I’ve heard them with Pass equipment. I kept staring at them. I expected Dr. Who to pop up.. They sure disappeared in a room. Jean-Luc Ponty was on the menu. I remember that I brought it.. The guy had isobaric subs made from 1" thick clear plastic. Quit a sight and sound. The drivers had the biggest motors I had ever seen, they must have weigh 50 pounds each. I’ll see If I can fin a pic.

Side Note:

HAY Crazy SUBS pics are cool. I like all the DIY stuff.

I’d give my eye teeth, If I had eye teeth for the ESS Transar ATD, that were all custom. MAN they look good, I know they sound good..

In Thiel's case, it's because the mastermind passed away, but I still think this speaker design is brilliant. With updated components and electronics as they age, Thiel can live on.

@jdoris "...Gallo series. Could sound very good indeed, and at very reasonable price point, esp. by the standards of today’s hobby.

I briefly had a pair of 3.5s or 3.6s, but could not get them to sing with the 30wpc amp I was running. I expect they wanted a bit of juice.

Interesting. I heard a pair of those floorstander Gallo 3s in a smaller room powered by a 100w EL34 stereo tube amplifier with some decent iron transformers behind it. The sound of that middle "CDT3 (Cylindrical Diaphragm Transducer)" component in that MTM type design was pretty neat. Like a circular flat ribbon of sorts. Smooth sound, quite surprising. My friend missed out on buying a used pair and kinda regrets it. A unique looking and sounding speaker in a small floorstander. I wonder if a pair of those new Strada 2 separate units with a REL sub would sound close.

When I bought the Gallo 3 series, I multiply auditioned the Strada 1s, and while I found them good with the Gallo sub, I had a clear preference for the 3s.

Interesting sidenote:  I've bought most of my speakers without hearing them, but the Gallo's were an exception, and I got to closely listen to both the Stradas and the 3s several times.  I've enjoyed almost all of my speakers, but the Gallo's lasted about a week, despite my loving the auditions.  As I said, I suspect power issues, despite the Gallos being rated down to 30w.

With the right amp, I could se an old pair of 3s being a steal, though I'd not want to find service on that CDT3.
