    Mackie SRM450v2 2-Way (1x12") Active PA Speaker Product Description

    Live Sound That Sounds Like It Should

    Live sound sometimes seems like a wild, uncaged animal-very hard to control. With the SRM Series Portable Active Loudspeakers, Mackie came up with the technology to help tame the beast, so you could focus on your performance, instead of being distracted by constant EQ and level tweaks. Now, with the SRM450v2, live sound is whipped completely into submission, giving you more control over your shows than ever. The SRM450v2 surpasses the performance of the original SRM450 to deliver pure studio monitor sound at more powerful, full-on loudspeaker levels. It's affordable, too-even though the SRM450v2 is a complete redesign from inside out, the musician-friendly price tag is maintained. With the SRM450v2, live never sounded so good...or behaved so well.

    Mackie SRM450 V2

    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(tm) 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 high-frequency waveguide, allowing for ultra-wide dispersion. This allows the SRM450v2 to deliver clear, smooth sound to audience members up to 45 degrees off axis. The 12-inch neodymium woofer provides a greater magnetic field with far less material, making the woofer extremely lightweight without sacrificing performance. The 3-inch voice coil allows the driver to run cooler, delivering consistent performance even after long hours of use. Mackie-designed Active electronics provide equalization, crossover, time alignment, and phase correction to enhance sonic performance. Protective circuitry includes over-excursion protection, low-line voltage shut-down, thermal protection, level dependent low-frequency roll-off and independent LF and HF limiters. The SRM450v2 features a number of dedicated controls including a mic/line switch, a single microphone and line input level control, and a contour switch for low-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 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 weather-resistant steel grille. The asymmetrical trapezoidal cabinet has been designed to provide an ideal floor monitoring position. 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.
