KLH model 20 twenty, 1965, made in USA

Virtually identical to the well-regarded Model 17. The 17s are 8 ohm, the 20s are 4ohm (but both use the same tweeters) The 17s have binding posts, 20s have RCA jacks--they were sold as part of the Model Twenty system with TT/receiver.

Woofer: 10"

Dimensions (WxHxD): 11-3/4" x 23-1/8" x 9"

The Loudspeakers - The Model Twenty Speaker systems are new, two-way acoustic-suspension designs capable of smooth and extended response with very low distortion. Each bookshelf enclosure houses a 10-inch high-compliance woofer and a 1-3/4-inch direct-radiator tweeter. The ability of the woofer's cone to move without restriction over a very long distance helps to provide excellent bass response, with low harmonic distortion even at very high listening levels. The design of the tweeter enables it both to respond precisely to the highest musical frequencies and to disperse these frequencies with remarkable uniformity over a wide area achieving extremely accurate musical definition and an open, uncolored sound quality. A carefully designed crossover network helps achieve a smooth transition be tween the operating ranges of woofer and tweeter, and incorporates a 3-position switch that adjusts the high-frequency level to suit any listening environment.

The bookshelf size of the speaker enclosures permits them to be placed unobtrusively wherever they provide optimum sound quality and fullest stereo coverage. The cabinets are finished on four sides to allow horizontal or vertical placement. Snap-out grille-cloth panels facilitate changing cloths to match a particular decor. The speakers are provided with 40 feet of easily-concealed cable.
