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 two years of extensive research and development, the first Sound Reinforcement Monitor was born — a loudspeaker that truly lived up to its name. The SRM450v2 continues the SRM450's tradition of studio monitor sound quality to deliver sound that makes any venue seem like a well-tuned studio.
Undoubtedly you've been to a show where the sound is all over the map. Stand in front of the band, 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 the SRM450v2 loudspeakers are on stage, 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 SRM450v2's wide dispersion pattern, which is achieved through its multi-cell horn throat aperture.
Stunning Bass via Servo Feedback Controlled
Many portable loudspeakers produce lows that lack substance, they just don't have it in 'em to give you that chest-pounding punch. But the SRM450v2 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 SRM450v2's servo feedback technology combined with its all-new woofer and 3-inch voice coil.
Based on Mackie's award-winning HR824mk2 studio monitor technology, the servo feedback damping electronic circuit within the SRM450v2 'locks' the woofer in place with the positive and negative outputs of the amplifier. This creates a solid direct-coupling that allows the SRM450v2 to deliver extremely deep bass from a small cabinet. The new lightweight woofer is lighter in mass, but still delivers the same deep low punch you expect. The new longer 3-inch 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
With its combination of Class D topology and Fast Recovery circuitry, the SRM450v2 operates with incredible efficiency and delivers much more power and clarity. With this 'Class D Fast Recovery amplification', the SRM450v2 handles maximum volume, and associated heat, with ease, so there's no unwanted noise, and no thermal problems. Even after hours of sustained use at near-peak levels, your sound remains clean and your SRM450v2 keeps cool.
Built-in Protection Circuitry for Long Life
Active loudspeakers are pushed hard: often to, or beyond, the limit. That's why Mackie have reliable protection circuitry built in to every one. The SRM450v2 employs a built-in limiter for less distortion at peak levels and an automatic sliding high pass filter to give you that little bit extra volume when the crowd demands more. Thanks to the advanced technology of its power supply and Class-D amp topology, the SRM450v2 is greater than 90 percent efficient, so 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 longer life.
Versatile, Portable, Tough
The SRM450v2 is flexible when it comes to mounting. You can pole mount it, fly it horizontally or vertically from it's M10 mounting points or use it as a wedge monitor on the floor. Now moving it into place is easier than ever. Weighing in at about 18 Kgs, you'll have plenty of strength left over to play after loading in.
