Mackie SRM450v3 12" 1000W Powered PA Loudspeaker System

1000W Biamplified Live Speaker with 12" LF Driver, 1.4 Titanium Dome Compression Driver, 2-channel Mixer, and On-board Digital Audio Processing (Each) It doesn't matter if you're a DJ, church, or Iron Maiden tribute band, you need loudspeakers that won't crap out in the middle of a show, or distort when you turn them up past 3. That's why Mackie designed the SRM450 - the first and only portable active 2-way loudspeaker with onboard bi-amplification, active crossovers, time-correction and renowned Mackie sound quality. Thanks to countless hours of R&D - and one very-hard-to-please Greg Mackie-the SRM450 delivers real, accurate bass down to 55Hz; midrange that's free from ear-fatiguing harshness; and detailed treble out to 20kHz. Better still, the SRM450 offers astonishingly wide dispersion that lets your whole audience hear clearly, whether they're in the front, back, or way out on the sides of the room. Above all, the SRM450s crank! Without a hint of distortion, they effortlessly achieve sound pressure levels beyond the legions of look-alike portable loudspeakers on the market today. Ultra-Wide DispersionEver been to a show where the music sounds great in front, but craps out once you get to the back or sides of the room? Mackie has, and that's why they gave the SRM450 a multi-cell horn throat aperture. Sure, it's hard to say, but what it does is allow for much wider and more even dispersion of high and mid frequencies - so the wallflowers get the same great listening experience as those up front.

Timing is EverythingIn most loudspeakers, the compression driver that reproduces mid and high-frequencies is located deep inside the enclosure, while the low-frequency driver is much closer to the front of the enclosure. With this setup, bass arrives at listeners' ears sooner than treble, muddying the sound. Mackie remedied these unfortunate laws of physics with high-zoot electronics which allow precise alignment among the system components with zero signal degradation. Read more. Better Than Your Average BoxAnyone 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.

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 toroidal transformer, massive storage capacitors, and state-of-the-art output transistors, all adding up to superior sound, night after night. Read more. Servo Feedback Controlled LF Transducer for Stunning BassBased 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. Superb Floor MonitorWhen the first warranty cards came back, Mackie noticed that a lot of folks were raving about what a great floor monitor the SRM450 made. Okay, it's super accurate. And it's designed to be tilted. But there had to be more reasons than that.
