Meyer’s 700-HP has almost twice the performance power of the popular Meyer Sound 650-P subwoofer, and the 700-HP subwoofer has become a standard across the industry. The 700iHP delivers a high and sustained level of work with extremely high impulse response and minimal distortion over its entire working range. The operating frequency range of 25 Hz to 150 Hz complements other Meyer Sound loudspeakers in both straight and curved arrays for sound applications that require the greatest possible headroom at low frequencies.

The active 700-HP consists of two Meyer Sound ferrofluid-cooled 18-inch long-stroke drivers, each with a 4-inch voice coil with a compact neodymium magnet structure, in a specially adapted, ventilated housing. An integrated dual-channel Class AB / H amplifier with complementary MOSFET power amps delivers a maximum output of 2250 watts (1125 watts per channel).

The active 700-HP achieves a maximum output of 139 dB SPL within its working frequency range at 1 meter. The amplifier, control electronics and power supply are integrated in a separate interchangeable module, which is attached to the back of the box.

The 700-HP's efficiently tuned cabinet houses two Meyer Sound-designed and -manufactured back-vented, long-excursion, 18-inch cone drivers. Each driver has 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 650-P subwoofer, the 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 grills 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.
