MartinLogan's dedicated in-house design & engineering team wanted to pack as much bass performance as possible into a sleek, compact design without compromising the detail, speed, and transparency required to keep up with our agile electrostatic panels. To accomplish this MartinLogan designed an extremely precise 24-Bit Vojtko DSP Engine in conjunction with a powerful 200-watt class-D amplifier to harness a stunning low-level performance—uncommon in cabinets this compact.
Advanced Vojtko Filtering
Proprietary Vojtko filtering technology is utilized for Ethos' electrostatic transducer. This audiophile quality network, derived from the CLX, is carefully hand-built using precision point-to-point wiring, polypropylene capacitors, massive air-core coils, and a custom wound E-I core transformer—flawlessly preserving micro-acoustic subtleties while effortlessly handling the broadest range of dynamics contained within even the most demanding sonic source.
PoweredForce™ Woofer & Passive Radiator Dynamic Duo
Ethos' 24-Bit Vojtko DSP Engine and 200-watt digital amplifier create powerfully detailed bass from a custom designed front-firing 8-inch aluminum-cone PoweredForce woofer and precisely matched down-firing 8-inch passive radiator. This unique radiator enhances bass output, much like a port, but without port induced noise and midrange resonance. Ethos' passive radiator utilizes a full woofer suspension design to achieve maximize linearity during massive excursion. Additionally, Ethos' proprietary intelligent DSP engine allowed our engineers to utilize a smaller-than-average passive radiator to obtain the appropriate level of bass performance required to flawlessly blend with the electrostatic panel while still maintaining a minimal footprint for the cabinet.
