* Mid-woofer power rating is figured using an electronic high pass crossover with a minimum crossover point of 60 Hz at 24 dB/Octave, 80 Hz at 18 dB/Octave, or 100 Hz at 12 dB/Octave.
* Tweeter power rating is figured using an electronic high pass crossover with a minimum crossover point of 3kHz at 24dB/Octave, 3.5kHz at 18dB/Octave, or 4kHz at 12dB/Octave.
Audio Dynamics speakers were designed to reproduce music with ultimate accuracy.
We chose a Basalt cone for its ability to deliver astonishing realism and detailed timbre across the harmonics. We then added an acoustically-transparent chemical to help the soft parts resist moisture.
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.
Our speakers will pull you into the musical performance and breath new life into your music collection.
