Utilizing the Koss
Theory of loudspeaker design and its computerized program, Koss engineers set
out to design the optimum 3 bandpass loudspeaker. The result is a system that
stands alone in delivering a high energy broadband response, a low distortion product,
and a high efficiency level. The CM/1020 utilizes a dual port design to achieve
proper cabinet tuning and greater structural stability. The specially-designed
10-inch woofer provides both a 3 dB gain in electrical efficiency as well as a
flat response over the low bandpass. The 4½ inch midrange driver and 1-inch
dome tweeter capture all the realism of your music without distortion. And to
unite all these outstanding elements, Koss utilizes a unique, seamless
crossover network. But no description can match the thrill of hearing the
CM/1020 in a live demonstration.
