MartinLogan Source

High-Performance Hybrid Electrostatic Loudspeaker

Source is the world's most affordable high-performance hybrid electrostatic loudspeaker. Incorporating ultra-high-resolution AirFrame™ technology (originally developed for MartinLogan's Summit loudspeaker) Source is capable of an exceptionally dynamic and realistic performance. An 8-inch woofer, MiniETC™ (Energy Transfer Coupler) spikes, and high-end crossover engineering further reinforce Source's high-end pedigree. The result? A stellar performer at an exceptional price.

MartinLogan's advanced AirFrame™ technology and MicroPerf Generation 2 diaphragm electrostatic transducer cover the audible acoustic range with unprecedented high-frequency accuracy and low-level sonic detail. A perfectly integrated, MartinLogan engineered high-resolution 8-inch woofer supplies an authoritative bass performance with extreme precision.

State-of-the-art audio transformer and crossover engineering ensure a transparent link from amplifier to electrostatic panel and woofer. Source's crossover employs a proprietary Vojtko™ topology for vanishingly low distortion and seamless driver integration. This precision-tuned network preserves miniscule sonic nuances while handling the full dynamics of any source with unparalleled source, precision, clarity, and openness.
