The benefits of MTM
design…
Sound waves radiating
from the high- and low-
frequency drivers in a
conventional design can
create an inconsistent
o-axis response, coupling
to create peaks at
some frequencies while
cancelling out others, and
narrowing the stereo image.
By centering a large silk
dome tweeter between two
smaller woofers that cover
the same frequency range,
the E44 and E66 reduce
component interference—
improving o-axis response
and spatial resolution. The
result is a more consistent
listening experience,
smoother frequency
response, and an ultra-
wide, detailed stereo sound
stage.
Combined with Kevlar LF
transducers…
In addition to its clean
sound and ‘punchy’ bass,
the weave and nature of the
Kevlar design in the dual
Eris E44 and E66 woofers
also works to break up any
reflected energy—so fewer
delayed reflections reach
the listener’s ear, resulting
in a less colored, more
cohesive sound. These dual
woofers operate in parallel
within the same frequency
range, acting to minimize
phase displacement to
aord a much wider sweet
spot, improved spatial
resolution, and optimal
stereo imaging.
Features found in both
the Eris E44 and Eris
E66…
