Our Chief Designer talks design, technology high-quality materials, low distortion, and a long family history of music.
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 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.
Low distortion.
The Cell bass driver units have a 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.
Mingus Orchestra’s dramatic cabinet is finished in Piano Black, with solid wood tops and bottoms handmade by local craftsmen in Sweden.
We use specially selected, medium-density fibreboard with optimum rigidity to create high-quality, resonance-free cabinets.
The shape and dimensions of the cabinet have been carefully considered to deal with reflections from the drivers: giving low resonance and diffraction control. The internal structure and bracing keep the cabinet rigid and resonance-free.
Each cabinet is finished with a precision veneer and lacquer. The lacquer is carefully built up of 7 layers, each hand-polished in between drying.
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 has always been important to the design of our cabinets – the right isolation can mean the difference between a good speaker and a great speaker.
We worked with IsoAcoustics to design and make Marten Isolators. With this precision product, the speaker feels completely isolated from the floor, reducing resonance and distortion – leaving the soundstage free. It also makes for richer, more controlled and dynamic bass.
On each isolator, the cog allows easy and absolute control of the height.
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.
