400watt, 12'' Active PA Loudspeaker - Pair

CONDITION: Speakers are as new, boxes have been opened to inspect.

The Mackie SRM450v2 is a full-range, portable, powered loudspeaker system providing high-output, ultra-wide dispersion and low-distortion performance in a compact, lightweight design. Two Fast Recovery amplifiers independently power a 12-inch neodymium woofer and a precision titanium compression driver. Mackie’s sophisticated Active electronics provide phase correction, crossover, time correction, equalization and protection circuitry.

A heat-treated titanium compression driver with multi-cell aperture directs pristine highs through an exponential highfrequency waveguide, allowing for ultra-wide dispersion. In fact, the SRM450v2 can deliver clear, smooth sound to audience members up to 45 degree off axis.

The 12-inch neodymium woofer provides a greater magnetic field with far less material, making the woofer extremely lightweight without sacrificing performance. Plus, a 3-inch voice coil allows the driver to run cooler, delivering consistent performance even after long hours of use.

Mackie-designed Active electronics provide a host of processing designed to enhance the performance of the SRM450v2. Equalization, crossover, time alignment, and phase correction are working at all times to improve sonic performance. Protective circuitry includes over-excursion protection, lowline voltage shut-down, thermal protection, level dependent low-frequency roll-off and independent LF and HF limiters.

The center of gravity, handle locations, handle design, position of fly-points and ease of use have been ergonomically designed. There is also an integrated pole mount cup and a weatherresistant steel grille. The asymmetrical trapezoidal cabinet has been designed to provide an ideal floor monitoring position.

The SRM450v2 features a number of dedicated controls including a mic/line switch, a single microphone and line-level control, and a contour switch for low-level or background-level sound reinforcement applications. There is also a timed turnoff feature that turns off the amplifiers if the signal drops below –45 dBu for three minutes.

The cabinet is constructed of high-pressure injected polypropylene. The enclosure features ample amounts of reinforcement ribbing and structural strengthening resulting in a strong, super-rigid design providing ideal acoustical characteristics.
