Here is what one of
the best audio mastering engineers has to say about the 20M and
two 15 EXP subwoofer Armada System
"I purchased a
complete 20M Armada system over a year ago which I use daily
for audio mastering. This system has simply allowed me to get
closer to creating a perfectly balanced master than I ever thought
possible."

Audio Model 20M Ambient Sound Monitor.
The 20M is a time coherent,
point source, first order, two-way acoustic suspension loudspeaker
system that is the result of years of research, innovation, and
independent thinking, that have yielded many evolutionary refinements.
As a result the 20M has exceptional ability to accurately reproduce
music and to retrieve the ambiance of the musical performance.
As proof of the "rightness" of the design, few loudspeaker
image as well as the 20M.
Several features contribute
to the performance of the 20M. The 20M's combination of time
coherent, point source, first order, two-way, acoustic suspension
designs coupled with innovative cabinet and crossover designs
and accurate voicing, make the Model 20M incredibly true to the
source.

"The
20M is a very different speaker ... because it uses a two-way
coaxial driver from SEAS that looks like a single driver. The
tweeter is mounted inside the woofer, right where the dustcap
would normally be. ...The idea in creating a driver like this
is so that the speaker acts as a point source -- in other words,
as close to a theoretical ideal of radiating sound from a single
area."

As a result of its time coherent,
point source, coincident driver array, the woofer and tweeter
have identical acoustic centers and identical directivites at
the crossover frequency. This produces a stable axiosymmetrical
radiation pattern with smooth power response.This is further
enhanced by a high quality minimalist four element first order
crossover network.
The cabinet of the 20M is finished
in real walnut wood veneer. It is elaborately braced and the
rear panel is sloped two degrees to eliminate box resonances
and colorations. Furthermore, the vertical edges of the cabinet
are accentuated with exotic Peruvian walnut hardwood inserts
that are rounded to prevent sonic refractions and to enhance
the appearance of the 20M.
