Ultra-Powerful 15-inch subwoofer with PBK room correction capability.
Dynamo™ 1500X features advanced MartinLogan engineering including a 650 watt (1300
watt peak) amplifier and a 15-inch low distortion woofer with a powerful magnet structure to
deliver huge excursion and output while preserving subtle bass detail. XLR, RCA, and 12-volt
trigger inputs guarantee connection flexibility while simplifying system integration.
Dynamo 1500X offers incredible power and detail with the added benefit
of PBK—a sophisticated room correction system. MartinLogan’s PBK (Perfect
Bass Kit), sold separately, uses your computer and a microphone, strategically
placed throughout the listening room, to tailor the subwoofer’s performance to
the unique acoustic properties of your listening environment. The result is pure,
clean, and powerful bass down to 20Hz.
