Audio Dynamics – Exceptional Acumen Conducive To Exceptional Products And Performance
Conceived in Missouri during 1993 and stemming from the audacious aural ambitions of Aaron White; Audio Dynamics is a company built upon the bedrock foundations of vast knowledge, accumulated experience and engineering acumen. A vessel created for the purpose of allowing Aaron and his team of astute engineers to freely express their exceptional expertise and craftsmanship. During its tenure Audio Dynamics has successfully realised Aaron’s vision of creating a vast stable of superb quality audio products; products that combine exceptional design methodologies and meticulous construction with a delectable and a most realistic musical performance.

Master Series – Accuracy Beyond Astounding
Not everyone is looking to be hammered into submission. On the contrary there’s an echelon of discerning audiophiles who desire supreme sound quality above all else. Articulated deep bass, delectably controlled midrange, and supremely accurate highs. Barriers are there to be broken, and budget is of secondary concern. This is the territory of the superb Master series from Audio Dynamics. Developed with every detail heavily scrutinised; the Master drivers are as close to aural perfection and can be found.

Design Ideologies
The superb Master series speakers were designed with no budget restriction, thus resulting in world class sound quality and industry leading performance.

Calling Upon The Big Guns
To achieve this, Audio Dynamics teamed up with a leading speaker engineer who is an absolute master of his craft. With several patents to his name, during his tenure he’s designed speakers for fortune 500 companies, top quality PA systems, recording engineer’s reference speakers in some of the top studios around the world and designed many a high-end microphones; many of which are used by Grammy award winning musicians. He also personally knows Wolfgang Klippel and was tasked with setting up the very first Klippel testing in the world.

A Solid Foundation
The Master series M15 subwoofer is a high stroke, low distortion subwoofer tailored for moderate to large sealed enclosures and infinite baffle applications. The M15 uses a composite fiber cone with a dual gap magnetic structure. The M15 yields 40 mm of peak to peak linear excursion and 65 mm peak to peak mechanical excursion. Whereas the 76.2 mm diameter voice coil with aluminum former ensures high power handling.

Advanced Diaphragm
The M15 subwoofer cone is a composite of three different fibers with a proprietary structural core. These four layers are laminated together with a high-strength resin that is vacuum impregnated into the assembly. The result is a very strong but light cone, so that rocking modes are reduced but cone flexion is eliminated.

Immense Tesla
The M15 subwoofer uses a Y35 grade ferrite magnet. With the machined 1010 grade steel for the yoke and washers, the resulting in-gap field strength is 0.5 Tesla. The dual twin layer, i.e. a total of four layers; pure copper voice coil configuration is offered in either two or four Ohm nominal per voice coil for maximum impedance flexibility.

Rock Solid Design
The 38 mm thick dual gap top plate assembly features a 20 mm tall and 14 mm deep rebate. This allows for extended travel and greatly flattened BL motor force over its entire stroke. The rebate is filled with a 3.5 mm thick aluminum ring to reduce inductance resulting in a usable bandwidth to 1000 Hz, for exceptional transient performance.

Design Features
The rich heritage of this astute and masterful designer, together with its ever-increasing technical acumen; is conducive to these components featuring a vast array of impressive design ideologies and latest technological advancements. We canvass some of these technologies further below.
