MAOP 10 – pair

Description

These rare drivers are supplied in pairs.

From time to time I have a few of these drivers available,  the Mark Audio MAOP (Micro Arc Oxidation Process or Plasma Electrolytic Oxidization) drivers are made to order and only available in small quantities. These wide band drivers have mainly only sold in China having been made in extremely small production runs and being extremely collectable by the local customers. This means not many have found their way out this far West.

The Magnetic Arc Oxidisation Process is done at extremely high temperature in a flux bath that is prone to differential temperatures (hot/cold spots) which can warp the cones. The process is 10 times the cost of normal cone production, at least half are scrapped as it does render cones unusable if they are warped even slightly. The MAOP process involves a chemical conversion where the cone material is converted into its crystalline oxide. The crystal grows both outward into the substrate and outward. As such the new coating is not a deposited coating it is part of the original structure which gives excellent adhesion. The large crystal structure provides excellent stiffness and resistance to damage. The crystalline structure also encapsulates microscopic voids. It is supposed that it is the blend of microscopic voids and stiff structure that lend the cone the audio properties of both the metal cone and the paper cone, accuracy and a listen all day quality.

After construction, each driver is individually measured in the anechoic chamber at the Markaudio factory and pair matched based on that data to within, 0.5% tolerance.  Each pair is supplied with individual electrical and acoustic measurements, but for the purposes of your own modelling the TS parameters are broadly similar to the Alpair 10.3.

If we show no stock above, please feel free to drop me a line and I’ll see if there are some pairs available to import.
