JM Series In-Ceiling Speakers
Inset Grille Audiophile Speakers
L5 Frame
Our proprietary design combines
an aluminum frame, ¾" sheet of MDF (medium density
fiberboard), a ½" sheet of ultra-dense HDF (high
density fiberboard) and three high-loss damping sheets. This
high-mass sandwich virtually eliminates excess vibrations,
reducing energy transfer from the speaker to the ceiling. This
reduces distortion, and improves impact and transient response.
Drive Units
Our Heavy Silk tweeter is the key
to our system’s performance. This high power handling,
broad dispersion drive unit spreads sound evenly throughout the
room in an 80° radial pattern.
Our anodized aluminum bass unit
stays pistonic throughout its operating range — for
reduced distortion and truer reproduction.
TransientEdge® Crossover
Topology
We’ve developed our own
high power handling capacitors for improved speed and attack.
Uniquely integrated into JM Series networks, you’ll hear
greater resolution in the mid-bass, and more atmosphere in the
high end.
Our exclusive Pi Space Tuning
overcomes “bloated”
midbass gain when the speaker is placed near walls — a
situation likely to occur when used as L/C/R’s.
Vocal Integrity® System
Design
We’ve designed and tested
our systems to exhibit the lowest level of distortion in the
critical midrange — especially off axis. This
requires attention to all elements of the design, from driver
parameters to crossover tolerances. The end result is a series
of speakers that outperform the field when used in theater
applications.
Flush To The Ceiling
Our frame sits just 2mm off the
ceiling, twice as shallow as the typical in-ceiling speaker.
Combined with our flat micro-perf grilles, the speakers cast a
minimal shadow, looking almost flush to the ceiling.
Weather Resistant Construction
You can place 900 Series speakers
in high humidity areas, like kitchens, bath, and protected
outdoor settings. All exposed components are weather resistant.
Model JM65 Speaker with L5 Frame.
Distributed Audio Systems
JM Series speakers reproduce all
the subtle details in music, and disperse the sound evenly
throughout the listening environment.
Theater Systems
Vocal Integrity® system
design allows use of these speakers as front L/C/R’s in
theater systems. Smooth octave-to-octave transition means
vocals are clear and distinct, on-screen effects are easy to
pin-point. High power handling allows JM speakers to run
full-range in theaters up to 4,500 ft3.
