he continues. “There were no issues with
weight, no issues with power, just the
box doing its job. It was great.”
Each JM-1P contains a 15-inch
woofer joined by a 4-inch compression
driver with a proprietary manifold cou-
pled to a constant-Q horn that provides
a 20-degree horizontal by 60-degree
vertical coverage. Components are
driven a proprietary 2-channel, class
AB/H power amplifier with comple-
mentary MOSFET output stages yields
an output of 1,275 watts.
The loudspeakers were joined by
two Meyer 700 HP dual- 18 subwoofers
per side on the deck, all tied together
with Galileo 616 digital processing.
House mix engineers helmed a Midas
XL200 console and had several outboard
effects devices available to deploy as
needed, including TC Electronic M3000
reverbs, Yamaha SPX9909 multi-effects
processors and BSS DPR-402/404 compressors and BSS-504 gates.

JRX115 (single- 15) and JRX215 (dual-
15) 2-way loudspeakers on stage.
Adrenaline Rush
Another interesting application of the
JM-1P loudspeakers came with the
system for the 1,458-seat Maisonneuve Theatre, which can be likened
to a modern-day rendition of a classical Italian theatre, with a main floor of
seating followed by two expansive bal-conies. Andrew Hope took a hands-on
role with this design.
“This room features an ideal geom-
etry to demonstrate what the JM-1P
can do, because we were able to cover
it, top to bottom, with two little clusters
of four boxes,” Hope explains. “To do
that with a line array, it would likely be
four to five times the size and weight,
and pull much more electricity.”
“The benefits of line arrays - or more
accurately line sources - are obvious when
you have to throw a long distance without
having to go vertical. Just like your typical
outdoor event,” he adds. “But when you
get into a soft-seat theater like the Mai-
sonneuve, with a relatively short throw
distance and quite a need for vertical
coverage, line arrays don’t do that as well.
Plus, there’s no natural sense of imaging
as you move around the room.
