Marten Dexter Trio Loudspeakers

The Marten Dexter Trio delivers much of the technology of the larger Dexter models in a more compact and room-friendly floorstanding loudspeaker. Handbuilt in Mölndal, Sweden, the Trio combines a Marten pure diamond tweeter with dual 7.5-inch ceramic mid/bass drivers in a sophisticated 2.5-way design.

With its M-Core cabinet, Loaded Reflex Line bass system, Jorma Duality internal wiring, and integrated Marten Isolators, the Dexter Trio is designed to deliver the transparency, speed, imaging, and natural musical presentation that define Marten.

Diamond and Ceramic Drivers

The Dexter Trio features a 1-inch Marten pure diamond tweeter, providing exceptional stiffness, low mass, fast transient response, and extremely low distortion.

Below it are two 7.5-inch Marten ceramic mid/bass drivers, combining high stiffness with low moving mass to deliver clarity through the midrange along with fast, controlled low-frequency performance.

Marten's Loaded Reflex Line manages bass through a shaped internal channel terminating in a wide downward-firing slot. The design reduces air velocity while producing deeper, more controlled bass and greater flexibility with room placement.

Built Like a Marten

The Dexter Trio uses Marten's M-Core triple-layer cabinet construction, engineered to minimize unwanted resonance, with a carbon-fiber laminate faceplate surrounding the tweeter.

Internal signal wiring is Jorma Duality, handmade in Sweden, while the mirror-polished stainless-steel supports incorporate Marten Isolators developed with IsoAcoustics to reduce resonance transfer between the cabinet and floor.

An optional Statement Edition upgrades the internal wiring to Jorma Statement and incorporates higher-grade crossover components.
