With the SRM Series Portable Active Loudspeakers, Mackie came up with the technology to allow you to focus on your performance, instead of being distracted by constant EQ and level tweaks. With the SRM450v2, thanks to its all-new designfrom adding new amps and transducers to a new lightweight power supplythe SRM450v2 surpasses the performance of the original SRM450 to deliver pure studio monitor sound at more powerful, full-on loudspeaker levels. The SRM450v2 is a complete redesign from inside out.
The "SRM" Stands for Sound Reinforcement Monitor
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. The SRM450v2 continues the SRM450s tradition of studio monitor sound quality - and trumps it - to deliver sound that makes any venue seem like a well-tuned studio.
When the SRM450v2 loudspeakers are on stage, no matter where you stand, you hear sound with impeccable stereo imaging, depth of field and definitionat full-on loudspeaker levels. This is due to the SRM450v2s 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 youre listening intently front and center, or playing it cool on the perimeter, youll hear the same great mix.
Stunning Bass via Servo Feedback Controlled, all new Neodymium Woofer
Many portable loudspeakers produce lows that lack substance, 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. Thats thanks to the SRM450v2s 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 woofers magnet is lighter in mass, therefore faster than ceramics, giving the SRM450v2s 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 Mackies 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 weve lovingly (and creatively) dubbed the technology, the SRM450v2 handles maximum volumeand associated heatwith ease, so theres 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. Read more.
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 youre not a professional acoustic technicianor rolling in cash so you can hire one. Our proven Active design does all the work for you. With our 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, thats completely plug-and-playno EQ needed. Learn whats inside.
Built-in Protection Circuitry for Long Life
We know our Active loudspeakers are pushed hardoften to, or beyond, the limit. Thats why we 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. And thanks to the advanced technology of its power supply and Class-D amp topology, the SRM450v2 is greater than 90 percent efficientmore 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, ToughAnd They Look Good, Too
When designing the SRM450v2, we considered every angle. From every angle is just how you can position it, toopole-mount 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, its the most versatile portable Active loudspeaker around. And now moving it into place is easier than ever. Weighing in at about 40 pounds11 pounds lighter than the original SRM450youll have plenty of strength left over to play after loading in. Plus, the SRM450v2 retains its rugged, Mackie "built-like-a-tank" durability, thanks to the polypropylene cabinetnow in a tasty hue of Midnight Blue. So not only do you get a portable loudspeaker that sounds phenomenal, you get one thats tough and portable for the road, and handsome enough for the show.
