In the past several years I have given away a pair of KLH Seventeens, KLH Sixes, Snell Type Ks and AR3as. As companion for my Jordans, I have kept a pair of Genesis Physics 1s. I haven't measured them, but the boxes look close to the "golden ratio"--they ring gracefully. The drivers are of wonderful quality, especially the inverted dome tweeters. (Mine are the early ones on the masonite panel.) To Burhoe's horror, I strap them to high, 30" stands well away from the walls. The crossover is a single, new Solen cap at 1.8 cycles. They sound fine with modern equipment, but they sound good with the el84 amp section of a Stromberg-Carlson integrated that I often use (4 ohm tap.) They "jump" at you the way that single drivers do.
My audiophile friends once ridiculed me at length when I told them that I liked the sound of a pair of Klipsch LaScalas.
