Mackie

2-way biamplified, optimized Active loudspeaker system with smooth, ultrawide dispersion.

The Mackie SRM450 v2 Active Speaker puts your focus on your performance instead of the distraction of constant EQ and level tweaks. While live sound can sometimes seem like a wild, uncaged animal, with the SRM450 Portable Active Loudspeaker, Mackie has created technology to help tame the beast.

Thanks to the Mackie SRM450 v2 speaker's all-new design—from adding new amps and transducers to a new lightweight power supply—the SRM450 v2 surpasses the performance of the original SRM450 to deliver pure studio monitor sound at more powerful, full-on loudspeaker levels. Mackie has also managed to keep the SRM450 v2 affordable for musicians despite a complete redesign from the inside out.

The "SRM" Stands for Sound Reinforcement Monitor
Over a decade ago, Greg Mackie and a dedicated team of engineers set out to create a portable loudspeaker that could deliver studio monitor sound quality. Unlike a relatively small, acoustically controlled studio where the sweet spot is well-defined, live venues vary greatly and most are far from acoustically balanced. Despite the challenges, after 2 years of extensive research and development, the first Mackie Sound Reinforcement Monitor was born—a loudspeaker that truly lived up to its name. The Mackie SRM450 v2 continues the SRM450's tradition of studio monitor sound quality delivering sound that makes any venue seem like a well-tuned studio.

Ultrawide Dispersion
Undoubtedly you've been to a show where the sound is all over the map. For instance, stand in front of the band and it sounds okay, but move a little to your left or right and all of a sudden you've got mud in your ears. When Mackie SRM450 v2 loudspeakers are onstage, no matter where you stand, you hear sound with impeccable stereo imaging, depth of field, and definition—at full-on loudspeaker levels. This is due to the Mackie SRM450 v2 speaker's wide dispersion pattern, which is achieved through its multi-cell horn throat aperture. The multi-cell horn throat aperture allows for much wider and more even dispersion of high and mid frequencies. So whether you're listening intently front and center, or playing it cool on the perimeter, you'll hear the same great mix.

Stunning Bass via Servo Feedback Controlled, all new Neodymium Woofer
Many portable loudspeakers produce lows that lack that chest-pounding punch. But the SRM450 v2 delivers astonishingly deep and defined bass frequencies. In fact, it outperforms the original SRM450, which was renowned for its ability to deliver real low-down sound. That's thanks to the SRM450 v2's servo feedback technology combined with its all-new neodymium woofer and 3" voice coil.

Based on Mackie's award-winning HR824mk2 studio monitor technology, the servo feedback damping electronic circuit within the Mackie SRM450 v2 locks the woofer in place with the positive and negative outputs of the amplifier. This creates a solid, direct-coupling that allows the SRM450 v2 to deliver extremely deep bass from a small cabinet. The new neodymium woofer's magnet is lighter in mass, therefore faster than ceramics, giving the SRM450 v2's bass more punch. The new longer 3" voice coil allows the woofer to handle heat more efficiently, so it produces a consistently full dynamic range—even at maximum output. So you get full, thumping, detailed lows even after long hours of use at near-peak volumes.

Super low distortion thanks to Mackie's own Class D, Fast Recovery Amplification
With its combination of Class D topology and Fast Recovery circuitry, the SRM450 v2 operates with incredible efficiency, and delivers much more power and clarity. With this Class D Fast Recovery amplification, the SRM450 v2 handles maximum volume—and associated heat—with ease, so there's no unwanted noise or thermal problems. Even after hours of sustained use at near-peak levels, your sound remains clean and your SRM450 v2 keeps cool.

Legendary Active Electronics
In a passive loudspeaker setup, an external amplifier is connected to a passive crossover inside the speaker, which distributes frequencies to the transducers. Because power amps and transducers vary widely in sound and quality, trying to match the right power amp with the right speaker can be challenging, especially if you're not a professional acoustic technician or rolling in cash so you can hire one. Mackie's proven Active design does all the work for you. With the SRM450 v2, you get a complete loudspeaker system, with complex electronics and carefully chosen components, all precisely tuned and tweaked to work together. The result is a loudspeaker with phenomenal sound quality and power that is completely plug-and-play—no EQ needed.

Built-In Protection Circuitry for Long Life
Active loudspeakers are pushed hard, often to, or beyond the limit. That's why Mackie built reliable protection circuitry into every unit. The SRM450 v2 employs a built-in limiter for less distortion at peak levels, and an automatic sliding high-pass filter to give you that little bit of extra volume when the crowd demands more. Thanks to the advanced technology of its power supply and Class D amp topology, the SRM450 v2 is greater than 90 percent efficient—more of the power from your outlet goes straight to the transducer, without the power supply and amp giving off loads of heat. Less heat means better performance and a longer life.

Versatile, Portable, Tough
When designing the SRM450 v2, Mackie considered every angle. You can still achieve great sound whether you polemount it from the bottom, fly it vertically or horizontally via its integrated M10 mounting points, or use it as a wedge monitor. With all this flexibility, it's one of the most versatile portable active loudspeakers around. Moving it into place is easier than ever too. Weighing in at about 40 lb.—11 lb. lighter than the original SRM450—you'll have plenty of strength left over to play after loading in. Plus, the SRM450 v2 retains its rugged, Mackie built-like-a-tank durability, thanks to the polypropylene cabinet.
