Polymer Audio Master


The Master is a mind boggling advance in loudspeaker art and engineering. A world first, the Master utilizes a dual diamond midrange mounted in an MTM configuration which effectively doubles the cone area of the diamond cones. The total surface area used for midrange reproduction is 48cm² of pure diamond. No other loudspeaker in the world today has been constructed to this level of ambition.

The advantages of increased surface area and this type of mounting creates further benefits from the already extraordinary diamond cone, the excursion is reduced in half and the larger surface area can push air in a way that closely mimics a live performance in a wide range of listening environments. The MTM mounting configuration tightly clustered around the tweeter creates a stable spherical radiation pattern that has never been accomplished before with diamond transducers.

An entirely new baffle surface has been developed just for the Master using a metal alloy that is 3.5 times stiffer than aircraft aluminum materials and simultaneously more damped. This eliminates the potential ringing inherent in aluminum and other metals and is the last word in mechanical distortion. The baffle surface has a complex three-dimensional shape to eliminate time smear caused by diffraction which scatters energy and inlaid merino wool absorbs it.

The mibass drivers used in this design have the lowest moving mass for a driver of its size and use a voice coil construction technique that enables a transient response typically characteristic of the best tweeters.

The crossover is a completely outboard structure using the world’s best components. Each crossover cabinet weighs 120lbs and is constructed to completely eliminate mechanical and electrical distortion bringing the noise floor to an absolute ideal. Following our design philosophy the crossover provides steep filter slopes while retaining a minimal parts count (half of what would normally be required). All of our crossovers include time alignment which is achieved entirely in the electrical domain through a passive network which provides the benefits of digital equalization but retains the purity of the best passive networks with short signal paths.
