Speaker System (400-4032) Features Faxback Doc. # 7240 The Mach Two uses a special new ferrofluid-cooled design. Ferrofluid is a magnetic fluid originally developed for the U.S. Space program. The result is improved power handling and smoother, more linear response. Ferrofluid conducts heat build-up away from the critical voice coil and 'sinks' it into the speaker structure. This heat sink effect makes it possible for the Mach Two to handle higher peak levels of power without burnout or distortion. The 15" (38 cm) high-compliance woofer speaker faithfully reproduces rich bass from 25 to 800 Hz. The 5" cone midrange speaker gives exceptionally smooth response from 800 to 6,000 Hz. The Mach Two is designed with a special dual radial super horn tweeter for remarkable response up to 40,000 Hz! Its wide dispersion characteristics provide superb imaging and add lifelike presence throughout the listening area. A deluxe inductive/capacitive crossover network achieves precise blending of the response characteristics of these speaker elements, producing a smooth, seamless response throughout the entire frequency range. The acoustical-mechanical design of the enclosure, and cone midrange speaker, and dual radial horn tweeter, results in unusually uniform dispersion. Incorporation of two controls, MIDRANGE and HIGH FREQUENCY, permit you to adjust speaker performance to the conditions in the listening area and to your own personal taste. (br-7/18/94)
