Overview
Technology earned, not borrowed.
Dexter Quartet is a 3-way floorstander sharing its architecture with the flagship — the same diamond tweeter, the same ceramic midrange, the same approach to cabinet and bass loading. For rooms where Quintet’s proportions exceed what the space calls for, Quartet delivers the essential character of the series without compromise in the frequency ranges that define it.
The design
Three drivers, resolved as one design.
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.
The tweeter is diamond. Not as an option. Not as an upgrade. It was the starting point for every design decision that followed.
Isolators & cabinet
The speaker disappears.
The music does not.
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.
Four finishes,
hand-applied.
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.
