The entry-level model of MartinLogan's renewed range of Dynamo active subwoofers combines a 203mm diameter inverted peripheral suspension polypropylene cone speaker with a 75W continuous amplifier, in order to offer maximum performance and versatility for a price. unparalleled. Equipped with Line (shared for LFE) and High Level inputs, the Dynamo 400 allows, despite its apparent simplicity, a level of detail and punch never seen before in bass reproduction, an extension of the exceptional response curve and a sound pressure level capable of satisfying the strictest demands in both music and cinema. Among the numerous and highly innovative engineering solutions incorporated in this versatile subwoofer, the first highlight is the use of inverted peripheral suspensions in the speaker it incorporates, which is combined with a high-power magnetic motor and an ultra-light and rigid diaphragm to guarantee high displacements required to obtain extraordinarily natural bass in each application. Regarding the internal amplifier, the Dynamo 400 uses a high-efficiency design configured in Class D equipped with very high-quality MOSFET transistors, transformers and noise suppression circuits, to which are added the sophisticated IME filter (“Inverse Mathematical Equalization” or Inverse Mathematical Equalization Filters”), which allows obtaining a much more precise low frequency response than that provided by the simple second-order, high-Q filters commonly used in subwoofers of the same price level.
