Picked these up recently from a fella in Hollywood, CA. Marantz Model 600, made only 1 year, 1980, last of 4 lines of Loudspeakers designed by Engineer Edmond May, just before his death in 1980. 36" tall, by 16" deep, by 15" wide, smoked glass tops, mirrored, bronze trim, wide dispersion modified LPF 2.25" Dome tweeters & 1.75" super tweeters, 5" long excursion midrange, 10" woofer, 25Hz to 29kHz/+/-3dB response curve, 200 watts power handling, 90dB SPL @ 1W/1M, crossover frequencies-700Hz/2800Hz/6500Hz, Cabinets laminated with genuine walnut veneer on sides, rear, front & top fascias, weight-75lbs each, grills-plywood frames with polyester cloth uniquely silkscreened to match the walnut veneer. Very unusual design, but very pretty to look at. Every time I look at them, I have a hard time looking away.
