Momento 2 uses the bespoke crossover technique developed for Coltrane Supreme 2. The first order crossover makes for absolutely perfect time and phase coherence; and flawless time coincidence.
The diamond drivers deliver crystal clear sound; combined with our signature crossover your music sounds as close to reality as we could engineer. Detailed, controlled and vibrant.
- First order crossover
- Accuton Cell drivers
- Jorma cables
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.
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.
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.
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.
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
The reduction of resonance is important to the design of our speakers – it can mean the difference between a good speaker and a great speaker. With IsoAcoustics we 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
- Optimised for cabinet weight
- Resists lateral movement and oscillations
- Reduces internal reflections
- Suitable for carpet
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.
