Description

The Marten Dexter Trio is a 2.5-way floorstander in Marten's Dexter series, pairing a pure diamond tweeter with two 7.5-inch ceramic mid/bass drivers in an M-Core triple-layer cabinet. The Loaded Reflex Line manages bass through a shaped internal channel with a downward-firing slotted port, extending frequency response to 21Hz at ±2dB. Jorma Duality wiring is standard; Statement Edition adds Jorma Statement wiring and upgraded crossover components. Handbuilt in Mölndal, Sweden.

Marten Dexter Trio

The Marten Dexter Trio is a 2.5-way floorstanding loudspeaker and the step-up model from the Dexter Duo in Marten's Dexter series. Where the Duo is a 2-way stand-mount built around a single ceramic mid/bass driver, the Trio uses two 7.5-inch ceramic mid/bass drivers in a floorstanding M-Core cabinet, extending the frequency response to 21Hz and increasing sensitivity to 91dB. The same diamond tweeter, the same bass loading approach, and the same cabinet construction standard apply across both models. The Dexter Trio is available in Standard and Statement Edition configurations, in four finishes, and is handbuilt in Mölndal, Sweden.

The Dexter Series

The Dexter series comprises four models: Dexter Duo, Dexter Trio, Dexter Quartet, and Dexter Quintet. All four share a common platform: a pure diamond tweeter derived from Marten's Coltrane Supreme Extreme project, triple-layer M-Core cabinet construction, a carbon fibre laminate faceplate, Jorma Duality internal wiring, and the Loaded Reflex Line bass loading system developed specifically for this range. The Dexter Trio and Dexter Duo are 2-way and 2.5-way designs using ceramic mid/bass drivers; the Dexter Quartet and Dexter Quintet are 3-way floorstanders that add a separate ceramic midrange and carbon fibre bass drivers.

Cabinet and Faceplate

The cabinet is M-Core triple-layer construction. The faceplate is a machined carbon fibre laminate shared with Marten's flagship models, providing rigidity and near-zero resonance as a structural base for the tweeter. Marten Isolators, developed with IsoAcoustics, decouple the cabinet from the floor to reduce resonance transfer.

Standard and Statement Edition

The Dexter Trio is available in two configurations. The Standard Edition uses Jorma Duality internal wiring throughout. The Statement Edition uses Jorma Statement internal wiring and highest-quality crossover components. Both versions share the same drivers, cabinet, bass loading, and overall design.

Finishes

The Dexter Trio is available in four finishes: True Grain Oak, Matte Walnut, Piano Walnut, and Piano Black. True Grain Oak is exclusive to the Dexter series. A dedicated stand in mirror polished stainless steel with Marten Isolators is included.

  1. Wooden speaker with a carbon fiber patterned driver on a gray background
    01

    Diamond Tweeter

    The 1-inch pure diamond tweeter in the Dexter Duo is derived from development work done on Marten's Coltrane Supreme Extreme project. Its diaphragm moves in pure piston motion beyond the limits of hearing, producing transient response that reflects what is recorded rather than approximating it. This tweeter is shared across all four Dexter models.
  2. Wooden speaker with a black driver unit on a wooden surface
    02

    Ceramic Mid/Bass Driver

    The Dexter Duo uses a 7.5-inch Marten ceramic mid/bass driver, the same unit used in the Dexter Trio. The ceramic diaphragm combines the stiffness needed for accuracy with the low mass needed for speed, handling the full range from the lower midrange downward.
  3. Wooden Marten dexter speaker bass loading port
    03

    Loaded Reflex Line

    The Loaded Reflex Line is a new bass loading system developed specifically for the Dexter series. It combines bass reflex and transmission line principles through a shaped internal channel and a wide downward-firing slotted port. The result is reduced air velocity, extended bass depth, and greater flexibility in room placement compared to conventional ported designs. Each Dexter model's bass loading is tuned independently to its driver configuration.
  4. Metal audio connector panel with 'Marten Dexter Quintet' branding on a wooden background

    Jorma Duality Wiring

    Jorma Duality, handmade in Sweden. Ultra-pure copper conductors forming a direct signal path from crossover to driver. Standard across every model in the series. Internal wiring is upgraded to Jorma Statement in the Dexter Statement models.
