Many moons ago, I took the opportunity (sans explicit permission) to listen to an "old" tube stereo system from the '60s or '70s, which used Acoustic Research speakers mounted in wood cabinets with expensive-looking speaker cloth, that look from the outside like the 1954 AR-1. What continues to interest me about these speakers was the use of, not the 12-15" woofer or one (or two?) dome tweeters, but an elliptical midrange, 4x6" or 5x7", mounted on what looked like a shelf between the woofer and tweeter(s), which looked to be canted slightly upward and out, as opposed to directly forward like the other drivers, which indicated to me (rightly or wrongly) that it was a sealed-back driver. It was difficult to "see what was going on in there" unless the light was right and the front of the speaker was viewed from a particular angle, so I'm not positive that I knew what I was looking at. Nonetheless...
Can anyone shed light as to what model this speaker system is/was?
Any additional info would also be of interest to me; i.e., was it a good speaker for its time? Expensive? Whatever else?
