The MAOP-treated model of Markaudio's largest-diameter Alpair11MS
A new frontier for the 8-inch metal cone full-range speaker
The MAOP_11MS is the latest model based on Markaudio's damperless Alpair11MS, which boasts the largest diameter in their lineup, enhanced with the unique MAOP treatment. In addition to the original delicate expressiveness of the damperless design, it merges with the superior damping characteristics unique to MAOP, achieving an exceptionally smooth and musical sound.
Pure Copper Rectangular Wire – Acoustic design refined to the extreme
This unit features a specially designed voice coil using Rectangle Pure Copper Wire. Similar to a high-performance racing engine, it is meticulously lightweight. The coil's characteristics allow for several advantages directly impacting sound quality, including a weight reduction of several tens of percent against the same magnetic force, reduced linear resistance, and suppression of self-resonance.
Moreover, attention has been given to the unit's structure: it uses a chassis made of a glass fiber and ABS resin mixture. A rubber cover is applied to the magnet to minimize the effect of resonant sound.
Thorough consideration of the often-overlooked rear fluid design
While the design of the enclosure incorporates many theories, the fluid characteristics at the rear of the speaker unit itself are often overlooked. The MAOP_11MS addresses this by applying a design based on fluid dynamics, maximizing the unit's potential and providing remarkably natural and transparent sound.
Highly acclaimed at audio events
The prototype of this unit was showcased as a listening station at audio events in Japan and received high praise from enthusiastic listeners. By introducing the unique damping power of MAOP to the delicate expressiveness of the conventional Alpair11MS, it achieves smooth and rich music playback. It attracts considerable attention as a model that further expands the potential of full-range drivers.
MAOP – Strong Field Oxidation Crystallization
MAOP (Micro-Arc Oxidation Process) is a special oxidation crystallization process applied to the surface of cones made of aluminum-magnesium alloy. This process involves oxidation over a long period of time in an alkaline electrolyzer solution with a high voltage of 700 V, forming countless microcrystalline structures on the surface of the cone. By applying this treatment, the surface of the cone changes to a unique crystal structure with reduced gloss. Crystals containing countless microscopic bubbles are formed, which have a significant impact on the acoustic properties.
MAOP is not just a coating, but a process that transforms the cone itself. As a result, the mass gain of the cone is limited to less than 0.4%, resulting in an overwhelmingly lighter finish compared to typical coatings. You can see countless crystals that look like sponges and microscopic air holes. This precise structure disperses and absorbs vibration energy appropriately while maintaining the rigidity of the metal, creating a damping effect similar to a pulp diaphragm. The result is an extremely flat frequency response and quiet, transparent sound quality.

The Ultimate Fusion of MAOP and Damperless
"The damperless construction and MAOP processing completely erased the muddiness of the sound."
The absolute freedom of vibration system due to the damperless system, combined with the ideal damping effect of the cone due to the MAOP treatment, completely eliminates the incidental sounds and muddiness of typical units, resulting in a sound with ultimate clarity and silence.
"The speed at which the sound rises and the reality of the reverberation that disappears is amazing."
The MAOP's lightweight weight and damperless construction make the transients (sound responsiveness) phenomenal. Not only does the sound rise quickly, but the minute reverberation and spatial information at the moment of fading are realistically reproduced, giving you a sense of realism as if you were in a live venue.
A sense of scale that goes beyond the common sense of a full range
"It is an overwhelming sense of scale and richness that goes beyond the framework of the full range."
The combination of the large diameter of the 6.5-inch class and the ideal diaphragm gives it an overwhelming sense of scale that goes beyond the common sense of a full-range unit, and a deep and rich low-frequency reproduction ability. The sound does not become thin even at low volumes, and it maintains a heavy musicality.
Quality Control and Ownership Value
"There is a high level of quality control and a pleasure of ownership as befits a limited edition model."
It is a limited edition model that has undergone a rigorous production process, and its manufacturing accuracy and acoustic characteristics are extremely matched. I feel the joy of owning both the texture of the unit when I hold it in my hand and the sound it plays.
