1 pair of MarkAudio MAOP_11v2 driver units

MAOP_11 is a MAOP based on the Pluvia11, Markaudio's newest unit design.
If the Alpair10v2 MAOP is the queen of the modern full-range design, the MAOP_11 is the king of the full-range. The MAOP_11 has the hall tone of a modern designed hall, while the Alpair10v2MAOP has the hall tone of a European hall.

MAOP11 is version 2 and has a softer suspension.
The low frequency range is more dynamic, and the ability to express fine details in the mid and high frequency range has been improved.

Voice coil with Rectangular Pure Copper Wire

MAOP_11 uses a voice coil made of pure copper rectangular wire specially designed for this model. The advantages of this coil are many: it is tens of percent lighter for the same magnetic force, has less linear resistance, and has less self-resonance.
In addition, the chassis is made of a mixture of fiberglass and ABS resin, and the magnets are wrapped in a rubber cover to dampen resonance noise transmitted to the magnets.
While fluid design of enclosures has been studied in various ways based on various theories and designs, the fluid in the back of the unit itself tends to be surprisingly neglected.

MAOP (Micro-Arc Oxidation Process Cone)
Strong field oxidation crystallization process

This is the name of the surface treatment for the matte-like, low-luster surface that is a feature of the MAOP series.

This process involves immersing alloy cones in an alkaline electrolytic solution with a very high voltage (700 V) for an extended period of time (1-2 weeks) to oxidize the surface and form crystals. This process changes the surface of the cone into a crystalline body with numerous flexible bubbles (with many holes), as shown in the photo. (This method changes the cone itself and is not a coating, so there is almost no increase in mass.)

You can see numerous small crystalline bodies and air holes that look like the surface of a sponge. The piles of metal and air holes created by this several-week process make the reproduced sound natural.

The new material, dumped by the cone, generates a micro-resonance pattern that passes over the surface of the metal diaphragm, a groundbreaking invention that achieves a damping effect similar to that of a pulp diaphragm.
