RSL was a house brand made for Roger Sound Labs - a California retailer that folded in the 80's. Never saw any independent tests published.
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.
