MarkAudio MAOP_11MS (Limited Model) Driver Unit 1 Set

The MAOP_11MS is the latest model based on the Alpair11MS, the largest diameter as a Markaudio damperless unit, and has been subjected to its own MAOP treatment. In addition to the damperless design, which originally has delicate expressive power, it combines the excellent damping characteristics unique to MAOP, resulting in a very smooth and musical sound.

Pure copper rectangle wire - Acoustic design pursued to the limit

This unit is equipped with a specially designed voice coil that uses Rectangle Pure Copper Wire (pure copper flat square wire). It has been thoroughly reduced in weight, like a high-performance racing engine. This coil has the advantage of being able to reduce the weight by several tens of percent against the same magnetic force, and has many advantages that directly lead to improved sound quality, such as reducing linear resistance and suppressing self-resonance.

Furthermore, we are particular about the unit structure and use a mixed chassis made of fiberglass and ABS resin. The magnet part is covered with a rubber cover to minimize the effect of resonant sounds.

It also handles the fluid design of the back, which is often overlooked.

While many theories are incorporated into the design of the enclosure, the fluid properties of the back of the speaker unit itself are often neglected. MAOP_11MS also focuses on this point and adopts a design based on fluid mechanics. It maximizes the potential of the unit and provides an incredibly natural and transparent sound.

Highly rated at audio events

The prototype of this machine was released as a preview device at an audio event in Japan and received high praise from enthusiastic listeners. The delicate expressiveness of the traditional Alpair11MS has been added to the braking power unique to MAOP, resulting in smooth and rich music reproduction. It has attracted a lot of attention as a model that further expands the possibilities of a full-range driver.

MAOP – Strong field oxidation crystallization treatment

MAOP (Micro-Arc Oxidation Process) is a special oxidation crystallization process applied to the surface of a magnesium aluminum alloy cone. This process involves oxidation progressing over a long period of time in an alkaline electrolyzer solution applied to a high voltage of 700V, forming countless fine crystal 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 fine bubbles form, which have a major impact on acoustic properties.

MAOP is not just a coating, it is a process that changes the cone itself. Therefore, the mass increase of the cone is kept to just under 0.4%, resulting in an overwhelmingly lighter finish compared to typical coatings. You can see countless crystals that look like sponges and fine air holes. This precision structure maintains the rigidity of the metal, while moderately disperses and absorbs vibrational energy, creating a damping effect that is like a pulp diaphragm. As a result, extremely flat frequency characteristics and quiet, transparent sound quality are achieved.
