Description
Audio Dynamics speakers were designed to reproduce music with ultimate accuracy.
MW653 Mid-woofer Overview
We’ve spent countless hours testing different cone materials that could stay rigid during extreme excursion and allow the speaker to maintain efficiency and incredible sound quality. Ultimately, we chose a cotton cloth and glass fiber composite honeycomb cone. We also incorporated our new S roll surround, shorting ring, and 35mm voice coil.
M1 Tweeter Overview
The Master Series M1 tweeter is a high stroke, low distortion multilayer fabric dome 25mm tweeter. This tweeter features exceptionally high stroke to allow lower crossover points without compression.
The M1 tweeter features a split-gap design which provides ±1.6mm of linear excursion, approximately 5 to 6 times that of most other tweeters. The result is a wider operational bandwidth – as low at 1500 Hz – and distortion reduced by up to a factor of 4.
The M1 use a specially developed dome material. The dome’s fabric is a lamination of silk, polyester, and cotton and treated with a proprietary compound to unify the layers but allow each to provide their own unique benefits. Silk adds the stretch/pull basic mechanical strength; polyester provides rigidity of shape; cotton provides improved damping.
The M1 does not use a rear chamber to lower its resonance; instead, a larger roll surround provides a lower resonance of the driver. This design allows for higher stroke as well, for full-range output down to 1500 Hz. And by removing the rear chamber, resonances from that chamber are eliminated. The elimination of the rear chamber results in an 11.7mm (15/32”) mounting depth for freedom of positioning.
The M1 comes with a chemically etched steel grille featuring an anti-resonant hole-pattern with size of opening optimized for dispersion. The grille is mounted to the main tweeter with a friction-fit gasket ensuring vibration-free operation and eliminating visible screws.
This component set handles extreme power and delivers the most dynamic and effortless mid bass and high frequencies of any drivers ever produced by Audio Dynamics.
