MarkAudio MAOP7_v2 1 pair of driver units

It is an astonishing wideband speaker unit that exceeds the common sense of the performance of a full-range unit. The driver combines the high-performance drive engine of the MAOP cone and the Pluvia 7HD in the vein of the former Alpair7 in a fiberglass chassis of the latest design.

MAOP7 is designed to be ideal for a general 12~20 tatami mat environment, and reproduces original sound with a very delicate, dynamic, and speedy feeling.

Voice coil with Rectangular Wire

The MAOP_7v2 uses rectangle copper wire for the voice coil, and the conversion efficiency in the magnetic field is about 30% more efficient than that of the round wire, so the drive weight (MMD) can be reduced, and the mid-range eddy current can be reduced, and the coil can be designed with fewer folded parts and a larger surface area, contributing to the sound quality of the MAOP7v2 over the entire range.

In addition, the reduction of eddy currents in the mid-range and the design of a large surface area with fewer coil folds contribute to the sound quality of the MAOP_7v2 over the entire range.

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

The matte glossy surface is a feature of the MAOP series, and this is the name of the surface treatment.

This process refers to the process of immersing an alloy cone in a solution in an alkaline electrolyzer with a very strong voltage (700V) for a long time (1~2 weeks) to oxidize the surface and produce crystals. By adopting this treatment, the surface of the cone changes to a crystalline body with countless flexible bubbles (many holes) as shown in the photo (this method changes the cone itself and is not a coating, so there is almost no mass increase)

You can see countless small crystalline bodies and air holes that look like the surface of a sponge. The piles of metal and air holes created after the process of several weeks make the reproduced sound natural.

This is a groundbreaking invention that achieves a damping effect similar to that of a pulp diaphragm on a metal diaphragm, thanks to a new material that dumps in a cone where micro-resonance patterns occur through this surface, resulting in characteristics that span a very flat wide bandwidth, which is why it is referred to as a quiet driver.
