Thanks to its all-new design—from adding new amps and transducers to a new lightweight power supply—the SRM450v2 surpasses the performance of the original SRM450 to deliver pure studio monitor sound at more powerful, full-on loudspeaker levels.
The SRM450V2 is designed to be a portable loudspeaker that can 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. The SRM450v2 continues the SRM450’s tradition of studio monitor sound quality—and trumps it—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. 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 hanging on the perimeter, you’ll hear the same great mix.
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 neodymium 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. And the new neodymium woofer’s magnet is lighter in mass, therefore faster than ceramics, giving the SRM450v2’s bass more punch. 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 thanks to Mackie’s own Class-D, Fast Recovery Amplification 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,” as we’ve lovingly (and creatively) dubbed the technology, 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.
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. Mackie's proven Active design does all the work for you. With the SRM450v2, 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’s completely plug-and-play—no EQ needed.
Active loudspeakers are pushed hard—often to, or beyond, the limit. That’s why the Mackie SRM450v2 has reliable protection circuitry built. 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. And thanks to the advanced technology of its power supply and Class-D amp topology, the SRM450v2 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 longer life.
