The MM-4 loudspeaker is a very compact, wide-range loudspeaker for high quality distributed system applications. In contrast to conventional low power 70-volt transformer based systems, the MM-4 connects directly to the amplifier and is capable of producing high sound pressure levels while dramatically reducing distortion and easing installation requirements. The MM-4 comprises a single 4-inch cone driver with a 16-ohm voice coil mounted in a sealed enclosure. The MM-4 draws 150 watts peak from the line, and produces 112.5 dB peak SPL. Typically, with four MM-4s connected in parallel on the line, the system requires a direct drive power amplifier capable of 600 watts continuous output (49 volts rms) into 4 ohms.
