CHAPTER 1
The Meyer Sound 700-HP ultrahigh-power subwoofer (Fig-
ure 1.1) sets a new standard for the power-to-size equation.
The 700-HP’s power and bandwidth handle high continu-
ous operating levels and extreme transient information with
minimal distortion in its operating frequency range.

optional rigging frame
Meyer Sound’s rigorous design approach has been ap-
plied 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 sys-
tem, the transducers, amplification and control electronics
of the 700-HP are created as a symbiotic system that opti-
mizes performance and maximizes its tremendous power.
The operating frequency range of 28 Hz to 150 Hz comple-
ments other Meyer Sound loudspeakers and line and cur-
vilinear arrays in sound reinforcement applications requir-
ing maximum headroom at the low end of the frequency
spectrum.
Features & Benefits
■
Stackable
■
Flyable using optional rigging kit
■
Extremely low distortion for ultimate low-frequency clar-
ity
■
Very high peak power yields excellent transient repro-
duction
■
Transportable in blocks using optional heavy duty
caster frame
■
Exceptionally reliable and durable
The 700-HP’s efficiently tuned cabinet houses two Meyer
Sound-designed and -manufactured back-vented, long-ex-
cursion, 18-inch cone drivers. Each driver features a 4-inch
voice coil and is rated to handle 1200 AES watts. The driv-
ers have also been engineered for extreme efficiency, using
high-gauss neodymium magnets for the most powerful
magnetic field strength. High magnetic field strength in-
creases the driver’s sensitivity, which yields greater output,
while keeping heat dissipation requirements within opera-
tional tolerances.
An integral two-channel class AB/H amplifier with comple-
mentary MOSFET output stages supplies total peak power
of 2250 watts (1125 watts per channel). With twice the
amplifier power of the 650-P subwoofer, the 700-HP pro-
duces 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 pro-
tect 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 maxi-
mum convenience in touring situations, the 700-HP can
even travel in stacks on the MCF-700 caster frame.
Applications
■
Stadiums, arenas and concert halls
■
Medium-to-large theatres and clubs
■
Theme parks
■
Cinema
The 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 11 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 700-HP include weather protec-
tion and finishes in custom colors for fixed installations and
other situations requiring specific cosmetics.
