Anyone heard of RSL monitor speakers?

I recently spotted a pair of these 4 ohm floor-standing speakers. They look a lot like Vandersteens, though the body is solid. (Same wraparound black cloth with wood top/bottom.) They appear to have a ribbon tweeter and 2 drivers. Is anyone familiar with this manufacturer? They are made in California, the model is #4200b. Any information is greatly appreciated.
not good, out of business, try the psb alphas, a better usage of your hard earned bux
If these were Manufactured in California,It may well be A company called Roger sound Labs, And i believe they went out of business about 10 years ago.
Yes, Roger Sound Labs from California. I remember seeing some of their stuff in late 70's early 80's when I lived in S.Cal. Seemed like pretty "average" consumer speakers.
