Was Reuben Guss the first to commercially offer "isobarik" loudspeakers ?

It would be nice to find some brochures. There's nearly two hours of Mr. Guss and Mr Karlson in the show linked below.

Hi-Fi Workbench WNCN-FM 3/7/64 (from Roger Russell's collection) with Eric Toline -Moderator and guests John Karlson of the KRC Corporation and Reuben Guss-Argus-X (sp?) Electronics

looking at a few AUDIO Annual Equipment Directory issues, Guss in "1984" had a system for $50,000. I think his largest system after that was $100,000 with 12-15" speakers per side.

It would be great if someone could dig up a brochure and post to the internet.

AUDIO's 1987 and 1988 Annual Equipment Directory list Reuben's top model at $100,000 with each side having 12-15 inch woofers. I don't think these were isobarik but probably more of a "column" configuration (?) If for regular height rooms, perhaps they were isobarik

Was Reuben the first to break the $100,000 price tag for stereo speakers?

Hi GM, Guss's patent shows a variable resistor in series with the inner driver. What do you figure that did as was dialed from "0" up? Is there a way to fudge that in hornresp ?

Greets!

Guessing it makes a 'new' set of averaged specs, though each with a different acoustic loading. 'Sounds' like something worth tinkering with.

Not without being able to input multiple different driver specs.

Don't recall ever knowing about such behemoth speakers or even his name beyond his patent, though long ago having done the math, know it takes these kinds of driver types, quantities to replicate a ~50% eff. horn system in 2pi space.
