The Swedish loudspeaker manufacturer Marten is debuting a new product line at High End Vienna, and this product line bears the name Dexter. The Dexter series consists of four models: a monitor model named Dexter Duo and a trio of floorstanding speakers named Trio, Quartet, and Quintet.
Marten Dexter: Four new loudspeakers
The Dexter series, consisting of the Duo, Trio, Quartet, and Quintet members, is designed to bring Marten's most advanced ideas to a wider range of listening environments. The Dexter Quintet, Dexter Quartet, Dexter Trio, and Dexter Duo share a common architecture: a Marten pure diamond tweeter, developed based on work on the Coltrane Supreme Extreme project, a new three-layer M-Core cabinet construction, and a new bass reflex system developed specifically for this series.
The Dexter Quintet and Dexter Quartet are three-way systems, each featuring a ceramic Marten midrange driver and carbon fiber Marten bass drivers. The Dexter Trio and Dexter Duo are built around a ceramic Marten midrange/bass driver, with the same diamond tweeter found throughout the series. All four models are internally wired with Jorma Duality cable and designed and built at the Marten factory in Sweden.
Loaded Reflex Line, Marten's new bass loading system, combines the principles of bass reflex and transmission line through a shaped internal channel and a wide, downward-facing slot port. This reduces air velocity, increases bass depth, and offers significantly more flexibility in room placement than conventional bass ports.
The Dexters are available in four finishes: True Grain Oak, Piano Walnut, Matte Walnut, and Piano Black. True Grain Oak is new to Marten and exclusive to this series. The Statement Edition, a version with an improved crossover and better internal cabling, is available for all four models.
Marten at High End Vienna 2026
The Dexter series makes its public debut at High End Vienna 2026. Incidentally, the complete Marten range, including the Coltrane, Mingus, Parker, and Oscar series, is represented in the partner areas spread throughout the show.
Dexter is available in four finishes. True Grain Oak is exclusive to Dexter — an oak with an open grain and a natural, tactile surface. The walnut finishes were developed specifically for this series and selected for their deep grain and natural, understated tone. Piano Black completes the range.
