A world class subwoofer from US Brand Martin Logan. Three 10-inch drivers, leading-edge technology and a unique force-canceling driver configuration yield deep, powerful, yet controlled bass that perfectly complements all speakers.
Building on the groundbreaking technology of the original Descent, the Descent i incorporates new features and enhancements that simplify system integration while improving performance. Its signature three-driver, force-canceling configuration virtually eliminates bass-blurring cabinet resonance. And each rugged, custom-built aluminum-cone driver is servo-locked to its own sophisticated, high-power amplifier. The result is dynamic, unrestrained output to the very lowest frequencies, yet with clarity and definition approaching that of electrostatic transducers.
