I found some info. Seems there was about 400 of these made and the inventor was semi well regarded for some things.

I would have initially deemed them crap having never seen them mentioned but they might be worth looking into. Although keeping them running if they are good might be a obstacle.
include SRSlabs in your search and you'll get some additional hits.
Some more info from searches...

"Any of my magnepans MGLR-1, .05 AND INCLUDING MY SRSLABS KLAYMAN SIGNATURE will blow away in imaging any dynamic speakers at major speaker stores costing hundreds more. The srslabs used to retail for $1200 went down to $400 til it was discontinued. With a sub, the klayman signatures are hard to beat in home theater set up at the price range, no $500-800 speaker go near it even $1000 dynamic speakers. The imaging is up there and lifelike similar to OHM'S radiation pattern."
