INTRODUCING THE JM-1P LOUDSPEAKER
The JM-1P self-powered loudspeaker is a high-Q, arrayable
loudspeaker suited for a wide range of applications. Utilizing
Meyer Sound's patented REM™ technology and trapezoidal
cabinet design, the JM-1P can be deployed in tightly-
packed array clusters to deliver coverage that is propor-
tional to the number of units in the array. While JM-1P point
source arrays are optimized for horizontal installations, they
can also be used vertically when necessary. With its scal-
able coverage and versatile QuickFly
®
rigging options, the
JM-1P loudspeaker can be used for touring, rental, and
fixed installations.
Boasting a wide operating frequency range of 53 Hz to
18 kHz, the JM-1P delivers a remarkably smooth sound with
ample low-frequency headroom. Designed and manufac-
tured at Meyer Sound headquarters in Berkeley, California,
the JM-1P's drivers include one low-frequency 15-inch long
excursion cone driver, and one high-frequency 4-inch com-
pression driver with an REM manifold coupled to an
extremely accurate horn. The JM-1P is distinguished by its
constant-Q horn that provides a 20-degree horizontal by 60-
degree vertical coverage. The unit's consistent polar
response and trapezoidal enclosure allow for tightly packed
arrays with minimal overlap in high frequencies.
