It doesn't matter if you're a DJ, a church, or an Iron Maiden tribute band, you need loudspeakers that won't go down in the middle of a show, or distort when you turn them up past 3. Anyone with a factory can build a box and stick some speakers in it (and that's just what many do). But low-frequency transducers in square boxes can create resonances that reflect off the rear wall and pass through the woofer cone out of phase, and ready to mess up your sound. The SRM450 enclosure is an asymmetrical monocoque design with no parallel surfaces, causing mid and high frequency resonances to be reflected at angles into internal damping materials, instead of interfering with the woofer doing its thing. Let's face it, 99 percent of the time compact PA speakers are cranked to the max. That's why the SRM450's beefy internal 400-watt amplifier section features dual FR series amps (one for each driver) both designed for extreme output. The amp section is built around a huge toroidial transformer, massive storage capacitors, and state-of-the-art output transistors, all adding up to superior sound, night after night. Based on Mackie's award-winning HR824 studio monitor technology, the servo feedback damping electronic circuit within the SRM450 provides amazing results. The circuit "locks" the woofer in place with the positive and negative outputs of the amplifier in a way that no external amp and passive woofer can ever achieve. This creates a solid direct-coupling that delivers extremely deep bass from a small cabinet.
