WHAT YOU GET
Power and control in perfect balance.

Coltrane Tenor 2 uses the bespoke crossover technique developed for Supreme 2. The first order crossover makes for absolutely perfect time and phase coherence; and flawless time coincidence.

  • 3-way bass reflex
  • First order crossover
  • Accuton Cell drivers
  • Jorma Prime cables
DIAMOND CONES
Sound that sparkles.

Pure Diamond is the ultimate material for speaker membranes. Used in the high-frequency range, its stiffness-to-weight ratio and internal sound velocity are unsurpassed.

Diamond is also the best heat conductor known to man. This is essential for loudspeaker membranes, providing the best heatsink for the voice coil; resulting in high power handling and very low compression.

The sonic character of our Diamond tweeters is not what you might expect. Others can sound ‘overly brilliant’ or ‘hard-as-diamond’. Harmonic distortion can be a problem too. Our crossover has been carefully designed to deal with this. In fact, you get the opposite – the Diamonds simply disappear, leaving only your music.

CERAMIC CONES
Advanced technology for natural sound.

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 cones 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 cones.

BASS DRIVERS
Low frequencies.
Low distortion.

The Cell bass driver units have long excursion, extremely low distortion levels and a hidden surround. Made of Aluminium sandwich honeycomb, the drivers offer rich, dynamic bass performance with a powerful presentation.

CABINETS
Resonance free

Years of research have shown that the best material for loudspeaker cabinets is Carbon Fibre laminate. We’ve tested many materials, but none offer such strength and rigidity. This makes the cabinet extremely inert and resonance-free across the whole frequency range. It also has a high internal damping factor despite its light weight.

We know that cabinet construction is just as important as the components you use inside, so Carbon Fibre is the ideal complement.

INTERNAL WIRING
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.

Optional upgrade: Jorma Design Statement

CONES AND PUCKS
Aerospace engineering.

Good isolation is paramount to get the best performance from our loudspeakers. We use Black Diamond Racing (BDR) cones and pucks for their supreme resistance to vibration and resonance.

BDR uses military-grade Carbon Fibre with state-of-the-art compounds, to create a material that is rigid, with a high internal damping factor and resonance control that is second to none.

CROSSOVER
We never follow the path of least resistance.

Marten worked tirelessly to refine the crossover so it would work perfectly with Accuton Cell drivers. It wasn’t an easy task, but it was the clear solution.

The first order crossover makes it possible to have perfect time and phase coherence; and flawless time coincidence. This means that all registers are generated at the exact same moment, as it was recorded. Just like live music.

  • Silver/Copper in oil/paper capacitors
  • Silver/Gold capacitors
  • Custom-made resistors
  • Jorma internal cabling
