What you get
Headline performance.

Its 3-way design uses Diamond tweeters by Accuton, achieving such a high clarity of sound that you’ll believe the musicians are playing in your room.

With control over the bass, two sandwich bass drivers deliver full and controlled sound over the lower frequencies – filling your space with rich music.

  • 3-way ported
  • Mundorf enhanced crossover
  • Accuton sandwich bass drivers
  • Bass control 3 x 1dB steps

“...Bird 2 is one of the finest examples of successful R&D in the world of loudspeakers”

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.

Two sandwich bass units using the latest Accuton technology, deliver exceptional power and control over lower frequencies.

Combined with the ceramic mid-range unit and custom-made 20mm diamond tweeter these rigid materials deliver a beautifully distortion-free sound.

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
Crafted for strength.

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 precision veneer and lacquering. The lacquer is carefully built up of 7 layers, each hand-polished in between drying.

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.

Cones and pucks
Material is everything.

Designed for Marten, the pucks and cones are made from high-tech engineering thermoplastic. This material has incredible stiffness, low friction, excellent dimensional stability and resonance control. The perfect balance of qualities needed for precision parts.

Our pucks and cones offer the isolation necessary for our speakers to perform at the peak of their capabilities.

Crossover
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.
