Marten Oscar Duo
—
What bookshelves were designed for.
Oscar Duo meets the demand for a reasonably-priced Marten speaker, without sacrifice to our renowned sound and quality. To achieve this we re-designed the build and created a bespoke driver.
- Custom designed drivers
- True Marten sound
- 2-way configuration
- Competitive price-point
The build offers exceptionally controlled and natural sound; true musicality that is the mark of a Marten speaker.
“Lights out, the Duos disappeared, producing a space-filling picture that I wouldn’t have thought possible from such small boxes.”
Michael Fremer | Stereophile
CERAMIC DOMES
Advanced technology for natural sound.
To retain their signature sound, Marten designed brand new drivers, allowing more control of the details.
Hard ceramic is light, yet extremely rigid, making it one of the best materials for speaker membranes – it’s also known as sapphire.
Marten’s ceramic domes have a high internal damping factor, because of a refined electrochemical process. The membrane also has a high material resonance frequency, meaning distortion is minimal; offering a level of clarity that is the holy grail for high end speaker domes.

CABINETS
Streamlined with precision.
The exterior is an exercise in minimalist design – no unnecessary details, no embellishment. Marten cabinet design is a balance of strength and elegance: the perfect complement to the sound.
The optional magnetic cover snaps on with a satisfying click, instantly streamlining the form without changing the sound.
INTERNAL WIRING
Premium cables for purer sound.
Marten uses Jorma Design internal wiring, for its exemplary quality and performance. Handmade in Sweden, the cables use separate + and – for enhanced shielding and the highest quality Copper.
This offers natural, transparent sound; the perfect choice for Marten’s speakers.
Cables are integral components, so they must work harmoniously with Oscar Trio’s precision design and build. Jorma Design delivers exactly what a Marten speaker demands.


STAND
Tailor-made for minimalism.
To ensure the stand would work perfectly with Oscar Duo, Marten designed it themselves, with as much consideration to resonance, as to form.
It had to be rigid enough to deal with vibrations, but also look good. After many iterations, Marten settled on a triple-pillar design, making the overall appearance lighter, while keeping it stable.
Dimensions
28 x 65.75 x 40cm (11 x 25.9 x 15.7″)
CROSSOVER
Low order for high dynamics.
Marten prefers to use lower-order crossovers, as the higher-order crossovers tend to limit the dynamics and details. Their second-order crossover has been creatively designed to make the best of the dynamic range.
- Copper foil air core coils
- Silver/Gold capacitors
- Supreme resistors
- Jorma internal cabling
