Not manufactured any more.

When I was 18 I heard those Dahlquists hooked up to a rack full of McIntosh electronics and was gobsmacked.  Thus began my continual upgrading into the best I could afford.  By the time I could afford them they were no longer made.  Sad.

=1 x5owner1 on the Gallo 3 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.

Weird that the company persists, but discontinued the special speaker in their line (the Strada is good, but not in the same league)

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..

Regards

@mijostyn..."Speakers come and go. For most there is a reason they are no longer made." 

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.
