Overview

Marten Dexter Duo Loudspeakers

The Marten Dexter Duo is the compact stand-mount model and entry point into the Dexter series, bringing core Marten technologies into a smaller two-way loudspeaker. Handbuilt in Sweden, the Dexter Duo combines a 1-inch Marten pure diamond tweeter with a 7.5-inch ceramic mid/bass driver.

Despite its compact dimensions, the Duo retains the same fundamental technologies found throughout the Dexter range, including Marten's M-Core cabinet construction, Loaded Reflex Line bass system, Jorma Duality internal wiring, and optional stand with integrated Marten Isolators.

Diamond and Ceramic Drivers

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

A 7.5-inch Marten ceramic mid/bass driver handles everything below the tweeter. Its combination of high stiffness and low moving mass contributes to the speed, transparency, and control that define the Dexter series.

Marten's Loaded Reflex Line manages bass through a shaped internal channel terminating in a wide downward-firing slot, helping the compact Duo produce controlled, extended low-frequency performance while providing greater flexibility with room placement.

Built Like a Marten

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

Internal signal wiring is Jorma Duality, handmade in Sweden.

Optional dedicated stands are finished in matte black and incorporate mirror-polished Marten Isolators developed with IsoAcoustics, helping decouple the loudspeaker from the floor and reduce unwanted resonance transfer.

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