Klipsch MCM-1900
The Klipsch MCM-1900 is a professional cinema loudspeaker system. It is a large-format four-way design, horn-loaded throughout. The low-frequency section uses a folded horn. The whole system is rated at 106 dB sensitivity (2.83V/1m), so it could produce enormous output from modest amplifier power. Frequency response is specified at 32 Hz to 16 kHz (±4 dB), with crossover points at 250 Hz, 1.2 kHz, and 6.5 kHz. Continuous power handling is rated at 100 watts, for a maximum SPL of 124 dB. Nominal impedance is 8 ohms.
Little is documented about the MCM-1900 beyond its specs. Period advertising in Recording Engineer (October 1980, p.121) put it in Klipsch's industrial/professional line, alongside the La Scala, aimed at applications "from nightclubs to concert halls" - venues where the Klipschorn's corner-horn approach wouldn't suffice. The same campaign ran in db magazine (May 1979, p.9), which called the MCM-1900 a "crowd pleaser" that no other system could match.
No production years, original pricing, dimensions, or weight figures have survived in the research record. The driver complement - woofer, midrange, and tweeter sizes - is also undocumented. The intent is clear enough: a high-efficiency horn system for professional cinema and large-venue sound, built on the same design philosophy as Klipsch's home loudspeakers but scaled for far bigger spaces.
