About the Ethos
The Martin Logan Ethos represents an advanced combination of sonic technologies establishing a new direction for audiophile design. Descended from the renowned CLX loudspeaker, it features the advanced XStat CLS electrostatic transducer with a proprietary Vojtko crossover topology for high efficiency and precision. The speaker includes an immensely dynamic 8-inch PoweredForce woofer and an 8-inch passive radiator, both driven by a 24-bit Vojtko DSP engine and a powerful 200-watt class-D amplifier, producing detailed bass down to 34Hz. The electrostatic panel measures 44" x 9.2" and provides a 30° horizontal dispersion and 44" vertical line source. The woofer and passive radiator are designed with cast baskets and aluminum and polypropylene cones respectively, optimized for low resonance and high excursion. The Ethos uses precision audiophile-grade components in its crossover and offers ±10dB bass control under 100Hz. It is housed in an ultra-rigid extruded aluminum AirFrame with custom ETC spikes for stability. The speaker is compatible with amplifiers rated 4 to 8 ohms and has a sensitivity of 92 dB/2.83 volts/meter. Dimensions are 59.33" × 10.73" × 18.23" and it weighs 42 lbs (19 kg). The Ethos is praised for its clarity, smoothness, and lack of coloration, providing a coherent and transparent soundstage with deep, powerful bass when properly set up. It is suitable for stereo or home theater front/surround use in medium to large rooms.
