Marten Coltrane 3
—
Power and control in perfect balance.
Coltrane 3 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 cables
This model upholds our philosophy of truth in music, by faithfully reproducing sound exactly as you hear it in reality.
“Their reproduction of every musical genre was completely convincing in terms of tonality, texture, and dynamics”

DIAMOND DOMES
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.
The sonic character of the diamond tweeter is not what you might expect. Others can sound ‘overly brilliant’ or ‘hard-as-diamond’. Harmonic distortion can be a problem too. Marten’s crossover has been carefully designed to deal with this. In fact, you get the opposite – the Diamonds simply disappear, leaving only your music.
Diamond is also the best heat conductor known to exist, which is essential for loudspeaker membranes, providing the best heatsink for the voice coil – resulting in high power handling and very low compression.
CERAMIC DOMES
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.
Marten’s ceramic domes have a high internal damping factor, due to a refined electrochemical process. The membrane has a high material resonance frequency, meaning distortion is minimal. This offers a level of clarity that is perfect for high end speaker domes.
BASS DRIVERS
Low frequencies. Low distortion.
Cell bass driver units have long excursion, extremely low distortion levels and a hidden surround. Made of aluminum sandwich honeycomb, the drivers offer rich, dynamic bass performance with a powerful presentation.
CABINETS
Resonance-Free
Years of research has shown that the best material for loudspeaker cabinets is Carbon Fibre laminate. Marten has tested many materials, but none offer such strength and rigidity. The result is cabinets that are extremely inert and resonance-free across the whole frequency range. It also has a high internal damping factor despite its light weight.
Marten knows that cabinet construction is just as important as the components they use inside; Carbon Fibre is the ideal material complement.
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 a speaker’s precision design and build. Jorma Design delivers exactly what a Marten speaker demands.
Optional upgrade: Jorma Design Statement
FEET
Next level isolation.
The reduction of resonance is important to the design of Marten speakers. It can mean the difference between a good speaker and a great speaker. With IsoAcoustics, Marten created Marten Isolators. This precision product allows the cabinet to be completely isolated from the floor, reducing resonance and distortion—leaving the soundstage free.
- Dynamic bass with increased power and control
- Natural openness and clarity
- Optimized for cabinet weight
- Resists lateral movement and oscillations
- Reduces internal reflections
- Suitable for carpet
CROSSOVER
Never follow the path of least resistance.
Marten worked tirelessly to refine the crossover so it would work perfectly with Accuton Cell drivers. 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.
- Copper foil air core coils
- Silver/Copper foil capacitors
- Silver foil capacitors
- Custom-made resistors
- Jorma internal cabling
