Versatile, compact, and affordable, Dynamo is engineered to MartinLogan’s highest standard to deliver superior bass performance.

Every element of Dynamo, from driver to amplifier to crossover to cabinet, is meticulously designed and manufactured to our highest standard. The result is staggering low-frequency performance for a subwoofer of its size and price. And its versatility is second to none. Variable phase and low-pass crossover controls enable custom tailoring to any system and environment. Dynamo can also be quickly reconfigured for either down- or front-firing operation.
