The same diamond tweeter found in every Dexter model. The same M-Core cabinet. The same approach to bass loading. What changes is scale; the intent is constant.\u003cbr\u003e\u003cbr\u003eDiamond and ceramic, resolved as one design.\u003cbr\u003eA 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.\u003cbr\u003e\u003cbr\u003eThe tweeter is diamond. Not as an option. Not as an upgrade. It was the starting point for every design decision that followed.\u003cbr\u003e\u003cbr\u003eDiamond Tweeter\u003cbr\u003eThe hardest diaphragm material available, with a stiffness-to-mass ratio no other material matches. Pistonic motion beyond the audible range — vanishingly low distortion, transient response that reflects what is recorded rather than approximating it.\u003cbr\u003e\u003cbr\u003eCeramic Midrange\u003cbr\u003eA 3.5″ ceramic midrange, designed by Marten, sits at the heart of Dexter Quartet. High stiffness and low mass keep it pistonic across its full operating range — the transparency and control it delivers define the tonal character of the design.\u003cbr\u003e\u003cbr\u003eCarbon Fibre Bass\u003cbr\u003eA 9.5″ carbon fibre cone driver handles the low frequencies in Dexter Quartet. High stiffness and low mass — the combination that keeps the cone pistonic at the frequencies that define bass dynamics and control.\u003cbr\u003e\u003cbr\u003eMulti-Diverse Crossover\u003cbr\u003eA custom crossover developed specifically for Dexter. Each order and transition point is resolved individually — not as a compromise between constraints, but as a deliberate choice for the drivers it serves.\u003cbr\u003e\u003cbr\u003eBass Loading\u003cbr\u003eThe Loaded Reflex Line manages bass through a shaped internal channel that exits through a wide downward-firing slot — a principle shared with Coltrane Quintet. Reduced air velocity. Deeper, more controlled output. Greater freedom in placement.\u003cbr\u003e\u003cbr\u003eJorma Duality Wiring\u003cbr\u003eJorma Duality, handmade in Sweden. Ultra-pure copper conductors forming a direct signal path from crossover to driver. Standard across every model in the series.\u003cbr\u003e\u003cbr\u003eThe speaker disappears. The music does not.\u003cbr\u003eMarten 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.\u003cbr\u003e\u003cbr\u003eFour finishes, hand-applied.\u003cbr\u003eFour 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.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cdiv\u003eConfiguration     2-way\u003cbr\u003eTweeter     1\" Marten pure
