Dexter Quintet is the flagship of the series. A three-way design in which every driver is designed by Marten, built around technologies that began at the very top of our range — and a speaker that exceeded its own specification during development.

Three drivers, each designed by Marten, each working in its own range. Around them, every element — cabinet, crossover, bass loading — has been developed to the same standard. A triple-layer cabinet built to remove resonance from the equation. A crossover resolved individually for the drivers it serves. A bass loading system that delivers deep, controlled output with minimal distortion. The integration is the design.

Marten Isolators, developed with IsoAcoustics, substantially decouple the cabinet from the floor — reducing resonance transfer and opening the soundstage. The cabinet is M-Core triple-layer construction, with a carbon fibre laminate faceplate surrounding the tweeter and midrange.

Four finishes, each expressing the same design in a different material. True Grain Oak — new to Marten and exclusive to the Dexter series — retains the natural texture of the wood, tactile in a way that is particular to this finish. The matte veneers are hand-sanded and sealed. The piano finishes are built up through multiple lacquer layers and polished to depth.
