Oscar Duo


What you get
Control in the driver’s seat.
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.

The build offers exceptionally controlled and natural sound; true musicality that is the mark of a Marten speaker.

  • Custom designed drivers
  • True Marten sound
  • 2-way
  • Competitive price-point

Oscar Duo sparked a design rethink to deliver Marten sound with new technology – bespoke drivers were created to make this possible. And that’s not the only thing that is custom: the optional stand is a Marten original. Innovation drove the creation of the Oscar series; understanding challenge, taking risks and rethinking design are the ashes from which Oscar was born.

Lights out, the Duos disappeared, producing a space-filling picture that I wouldn’t have thought possible from such small boxes.”

Advanced technology for natural sound.
To keep the same Marten sound we 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.

Our 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.

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 compliment to the sound.

The optional magnetic cover snaps on with a satisfying click, instantly streamlining the form without changing the sound.

Premium cables for purer sound.
We use 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 our speakers.

Cables are integral components, so they must work harmoniously with our precision design and build. Jorma Design delivers exactly what a Marten speaker demands.

Tailor-made for minimalism.
To ensure the stand would work perfectly with Oscar Duo, we designed it ourselves – 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, we settled on a triple pillar design: making the overall appearance lighter, while keeping it stable.

Levels of isolation
By reducing contact with the supporting surface, spikes are a tried-and-tested method for stand speakers.

Low order for high dynamics.
We prefer to use lower order crossovers, as the higher order crossovers tend to limit the dynamics and details. Our second order crossover has been creatively designed to make the best of the dynamic range.

Pursuit Perfect System
Oscar Duo falls under the expert scrutiny of Terry Ellis at Pursuit Perfect System. This review offers some great validation for our small but mighty model.

They have just got a very full and full bodied sound and easily do room filling bass like you would expect from much bigger speakers.”

Give your apartment a promotion.
Oscar are great all-round speakers; with absolute ease of placement, they’ll sound great in smaller apartments as well as larger spaces. With sound so solid and tight, it fills a room and feels like a speaker with a much larger footprint.
