MarkAudio MAOP_11v2 Driver Unit Set

The MAOP_11 is based on Markaudio's latest unit design, the Pluvia11, adapted into the MAOP format.
In terms of sound, if we liken the Alpair10v2MAOP to the queen of modern full-range design, the MAOP_11 can be considered the king of full-range. The impression of the sound is like comparing the same live recording: the former feels like a European hall, while the MAOP_11 feels like a hall designed with a modern approach.

The MAOP11 is version 2, featuring a softer suspension.
It delivers more dynamic bass and improved fine expression in the mid to high ranges.

Voice Coil Using Rectangular Pure Copper Wire

The MAOP_11 adopts a voice coil made from rectangular pure copper wire, specifically for this model. This coil offers many advantages: it can reduce weight by tens of percent compared to the same magnetic force, and it suppresses linear resistance and self-resonance, among other benefits.
Additionally, the chassis uses a mix of fiberglass and ABS resin, and the magnet is covered with a rubber cover to damp resonant sounds transmitted to the magnet.
While fluid design for the enclosure is carefully considered based on various theories and designs, the fluid aspects behind the unit itself tend to be surprisingly overlooked.

MAOP (Micro-Arc Oxidation Process Cone)
High Electric Field Oxidation Crystallization Process

The matte-like, glossy-suppressed surface is a characteristic of the MAOP series, and this is the name of the surface treatment.

This treatment refers to the process of immersing an alloy cone for an extended period (1–2 weeks) in a solution of an alkaline electrolytic cell subjected to a very high voltage (700V), generating crystals on its surface while oxidizing it. By adopting this treatment, the surface of the cone transforms into a crystal structure with numerous flexible air bubbles (many holes), as shown in the photo (this method alters the cone itself rather than coating it, so there is almost no increase in mass).

Countless small crystals and air holes can be seen on the surface, resembling a sponge. The metal peaks and air holes generated over this several-week process make reproduced sound natural.

This groundbreaking invention uses a new material in which micro-resonance patterns occur across the cone, providing a damping effect similar to that of a pulp diaphragm on a metal diaphragm. It is the reason why these are said to be quiet drivers, achieving extremely flat, wideband characteristics.

Sound Quality Fit for a Flagship Model

"Boasts remarkable depth in the sound background and overwhelming resolution."

Due to the exceptionally low noise floor and high damping effect from MAOP treatment, the sound background is extremely deep and quiet. The sound that emerges from it possesses overwhelming resolution, accurately reproducing delicate details and the sense of air.

"No harsh resonance, very neutral sound quality."

While maintaining the rigidity of the aluminum-magnesium alloy, the typical auxiliary sounds and peaks of metal cones have been eliminated, achieving extremely neutral and natural timbre. There is no coloration from the material, allowing the music's original resonance to be fully expressed.

6.5-Inch Diameter: Scale and Stability

"The 6.5-inch diameter adds stability and weight to the music."

With ample diaphragm area, this provides rich scale and sound stability that small-diameter units cannot deliver, particularly during the playback of large ensemble pieces.

"The bass expression is rich, tight, yet deep."

While offering high control performance through MAOP processing, it is capable of expressing deep, sinking bass thanks to its large diameter. The low range is tight and controlled, yet at the same time possesses ample volume and depth.
