Mackie SRM450 V3 Powered Loudspeaker (1000 Watts, 1x12")

Loaded with 1000 watts of bi-amplified power, smart DSP modes and an automatic feedback destroyer, Mackie's third-gen SRM450s fill the room with clear sound.

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 Dispersion

Ever 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 Everything

In most read more 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.

Better Than Your Average Box

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.

Dual FR Series Amplifiers

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 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.

Servo Feedback Controlled LF Transducer for Stunning Bass

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.

Superb Floor Monitor

When 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.

"Awesome improvement from the SRM 450 v2"
Overall: 3.5 out of 5 stars
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Bought one or these units to go with 2 existing SRM V2's and I can tell you that Mackie has now gone to to toe with QSC's K12. the bass in the new V3 is punchier, the highs have been cleaned up and the HD Sound is so crisp it's almost hard to believe they could make this much improvement in one swoop. I did have a static issue come up in the unit within an hour of play but zzSound has had another replacement on my doorstep within 3 days so I chalking this up to a hiccup Love it !!!
