| Meyer Sound’s rigorous design approach has been
applied to extract the greatest efficiency from every part of the system,
resulting in the 700-HP’s effortless reproduction of low frequency
transient information. As a self-powered system, the transducers, amplification
and control electronics of the 700-HP are created as a symbiotic system
that optimizes performance and maximizes its tremendous power.
The operating frequency range of 28 Hz to 150 Hz complements other Meyer
Sound loudspeakers and line and curvilinear arrays in sound reinforcement
applications requiring maximum headroom at the low end of the frequency
spectrum.
The Meyer Sound 700-HP's efficiently tuned cabinet houses two Meyer Sound-designed
and -manufactured back-vented, long-excursion, 18-inch cone drivers. Each
driver features a 4-inch voice coil and is rated to handle 1200 AES watts.
The drivers have also been engineered for extreme efficiency, using high-gauss
neodymium magnets for the most powerful magnetic field strength. High
magnetic field strength increases the driver’s sensitivity, which
yields greater output, while keeping heat dissipation requirements within
operational tolerances.
An integral two-channel class AB/H amplifier with complementary MOSFET
output stages supplies total peak power of 2250 watts (1125 watts per
channel). With twice the amplifier power of the Meyer Sound 650-P subwoofer,
the Meyer Sound 700-HP produces an average of 3 dB more overall SPL, with
enormous headroom to accommodate the most extreme demands with ease. Recent
tests conducted by Meyer Sound show the 700-HP producing significantly
higher output than other "high-power" subwoofers.
The amplifier, control electronics and power supply are integrated into
a single, field-replaceable module mounted in the rear of the cabinet.
The cabinet is constructed of multi-ply hardwood and coated with a textured
black finish. Integral metal grilles lined with acoustical black mesh
protect the cone drivers. Designed mainly for stage or ground placement,
the stackable 700-HP includes plastic skids on the bottom of the unit,
preventing damage to the enclosure or the unit below. The skids align
with slots on the cabinet’s upper surfaces ensuring secure, aligned
stacking. For maximum convenience in touring situations, the 700-HP can
even travel in stacks on the MCF-700 caster frame.
The Meyer Sound 700-HP is truck-smart, with exterior cabinet dimensions
suitable for both European and US truck widths. An optional QuickFly rigging
kit is available, installed at the factory or as a field upgrade. Up to
10 cabinets can be suspended from the optional MTG-700 top grid in a straight
hang at a 7:1 safety factor.
Options available for the Meyer Sound 700-HP include weather protection
and finishes in custom colors for fixed installations and other situations
requiring specific cosmetics.
An optional RMS remote monitoring system module allows comprehensive
monitoring of all key system parameters on any RMS-equipped host PC. In
addition, Meyer Sound’s MAPP Online multipurpose acoustical prediction
program allows quick prediction of coverage, frequency response, impulse
response and maximum output of the 700-HP and other Meyer Sound loudspeakers
and loudspeaker systems.
