Resolved from
the top down
Dexter, a new series from Marten.
Four models, one brief
The right loudspeaker does one thing: it puts the listener alone with the music. Dexter Quintet, Dexter Quartet, Dexter Trio, and Dexter Duo each do exactly that — at whichever scale the room demands.
Everything for a reason
A 1" Marten pure diamond tweeter is shared across all four models. Each design then specifies its own driver configuration alongside a new bass loading system — every element chosen for a specific role.
The hardest material available. On every model.
The 1" Marten pure diamond tweeter in Dexter is derived from the Coltrane Supreme Extreme project. Its diaphragm moves in perfect piston motion beyond the limits of hearing — producing transient response that reflects what is recorded rather than approximating it.
Midrange resolution without colouration.
The 3.5" Marten ceramic midrange driver handles the frequencies where most musical information lives. Its stiff, light diaphragm delivers accurate transient response in the range that determines how real a recording sounds.
A single driver from midrange to bass.
The 7.5" Marten ceramic mid/bass driver in Dexter Trio and Dexter Duo handles everything from the lower midrange down. The ceramic diaphragm combines the stiffness needed for accuracy with the low mass needed for speed.
Carbon fibre bass. Built for control.
Two 9.5" Marten carbon fibre bass drivers handle the low frequencies in Dexter Quintet and Dexter Quartet. Carbon fibre gives the diaphragm the stiffness-to-mass ratio needed to track fast transients without lag or smear.
A platform for precision.
The carbon fibre laminate faceplate is machined for rigidity and near-zero resonance — forming a stable acoustic platform for the drivers it surrounds. The woven carbon finish is consistent across all four models.
Built for easier placement.
The Loaded Reflex Line is new to Marten — a bass loading system developed specifically for the Dexter series. Each model's bass loading is tuned independently, accounting for its driver configuration. A downward-firing port reduces sensitivity to room boundaries, making each model easier to position.
We brought the technology of our most advanced series to Dexter. The ambition, as always, was a speaker that reveals nothing of itself.

Five recordings from a library built over years.
Music is how we listen, how we test, and how we know when something is right.
-
Bunny Gerry Mulligan & Johnny HodgesGerry Mulligan Meets Johnny Hodges · Verve, 1960The baritone saxophone occupies the lower midrange with unusual warmth. Any speaker that colours that register gives itself away immediately.
-
Spirit HiromiAlive · Telarc, 2014Technically exacting piano performance. The attack and decay of each note tests a driver's ability to start and stop cleanly.
-
Hit the Ground Lizz WrightDreaming Wide Awake · Verve, 2005A voice rooted in gospel and jazz, recorded with depth and body. Tests how a speaker renders the space between singer and microphone.
-
One Dove Antony and the JohnsonsThe Crying Light · Secretly Canadian, 2009A voice of extraordinary range and delicacy, spare accompaniment. Tests how completely a speaker disappears at low listening levels.
-
Röda sten Albin Lee MeldauPå svenska · Mayfly, 2020Intimate, close-recorded Swedish folk. The vocal is unguarded — any midrange colouration is immediately apparent.
Three decades.
Five series.
Dexter joins a range built over three decades — each series a distinct proposition, each built around the same commitment to resolution and long-term musical satisfaction.
