About the Source
The MartinLogan Source is a hybrid electrostatic floorstanding loudspeaker combining a 28-inch Generation 2 CLS™ electrostatic panel with an 8-inch high-excursion paper-cone woofer in a bass-reflex enclosure. Its 470 Hz crossover, 90 dB sensitivity, and 20–400 watts-per-channel recommended amplifier range make it suitable for stereo and home-theater systems. The speaker has a nominal 5-ohm impedance, with a 1.6-ohm minimum at 20 kHz, and is specified for use with amplifiers rated for 4-, 6-, or 8-ohm loads. The electrostatic panel requires connection to mains power for operation.
