The SRM450v2 from Mackie is a professional-quality active loudspeaker designed to provide studio-quality sound from a reinforcement speaker. The rugged cabinet houses a 12" neodymium woofer with a 3" voice coil, which is servo-controlled for tight, punchy bass. The 1.75" titanium tweeter provides smooth, clear treble. The drivers are powered by a 300W Class-D low frequency amplifier and a 100W high frequency amp for a strong sound with no distortion.
The loudspeaker features XLR input and pass-thru connectors for connecting to virtually any professional sound system. It also offers Mackie's Active Electronic time alignment, phase correction, and EQ so you can achieve the perfect sound for your environment. The multi-cell horn throat aperture provides an ultra-wide dispersion so your listeners hear nothing but great sound, no matter where they're located.
The lightweight and rugged speaker is ideal for travel, weighing in at a mere 40 pounds. The cabinet can be flown, pole-mounted, or placed on stage vertically or as a wedge for terrific installation options. Combine all of these great options with built-in protection circuitry and you've got a road-worthy active loudspeaker that's truly designed to last.
