Not manufactured any more.

Speaking of Pass. I’ve heard these. I just wish I could hear a Rushmore. I heard some of his horns about 25 or 30 years ago. Huge speakers I’ll see if I can hunt up a pic or two.

Nelson Pass, I’ve heard these speakers and 2 or 3 slightly different versions.

Single concentric drivers every time. I love horns.

Now if mozartfan would pay just a little attention he might see something interesting for a dual purpose single chassis driver and a well designed horn. 7 watts with a 101 sensitivity is incredibly loud..

If you looked up through the throat they weren't matched very well at the flange connections. We matching the ports on ours. That top "U" had highland sheep wool. The best sounding was rough coat the last 18" or so of the outlet. I ran mine with MC240 Macs. Just about 30 watts to much. I wish I would have had a MC225 at the time. That would have been the ticket.. :-)

Not according to Mr Pass though. :-) 

He was designing Threshold at the time I think.. It was a while back.. Sure supported his products through the years. See him just popup in a Pass talk group..

These are my RMx Elixirs after sound coat was added a few years back we were seeing if it made any difference with a HDF cabinet.. There is a rear fire section now and one of the neo 8 is in the rear position and a AC 8" ribbon is put in its place in the front. Dual Mono Pole.

There is a 1.5 BB Isolation plate with pods and a Stainless wrap along with a 30lb polished stainless cap. Almost 500lbs just for the monitors. I don't use the bass section. I'm thinking of pulling the drivers, blanking the openings and adding 50lbs of activated charcoal per cabinet. They are one of a kind now for sure. There were only 16 pairs ever made and under 6 in the US. 9 total left.. 2 sets of 3 are part of the 9 sets. James B. Trunural processor with Ampzilla amps.. 

FUN speakers. I'm not kidding 10-500 watts.. 92 sensitivity. I know they have seen 1000 watts. Never an issue. Mine are 13 years old.. They will last another 50 years.

IMF the whole series TLS 50 and 80 were my favorites
