Overview
Technology earned, not borrowed.
Dexter Trio is a 2.5-way floorstander built around the same technologies as the rest of the series. Diamond tweeter, M-Core cabinet, Loaded Reflex Line — nothing has been simplified to reach this form factor. The result is a speaker that works with its environment rather than demanding particular conditions from it.
The design
Diamond and ceramic, resolved as one design.
A diamond tweeter and two ceramic mid/bass drivers, each designed by Marten. Around them, every element — cabinet, crossover, bass loading — developed to the same standard as the rest of the series. 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.
