Product Details: Mackie SRM450 V2 Powered PA Speaker - 12 Inch, 400 Watts, BiAmped

The Mackie SRM450 v2 delivers live sound that sounds like it should!


The SRM450v2 Active loudspeaker combines superior quality with innovative technology to bring ultimate performance - and reliability - to Mackie's legendary Sound Reinforcement Monitor (SRM) series. The SRM450v2 retains the best of the original SRM design, including Mackie signature Active architecture and its renowned rugged durability. But with ultra-efficient switching power supplies, a lightweight neodymium woofer, an all-new compression driver and Class-D Fast Recovery amplification (300W LF/100W HF), the SRM450v2 packs way more power, clarity and punch. And its wide dispersion, outstanding bass extension and ultra-low distortion mean the SRM450 v2 delivers pure studio monitor fidelity at full-on loudspeaker levels. Thanks to the SRM450v2, live has never sounded so good.

Mackie SRM v2 Speakers
It started with the SRM Series. The first and only portable loudspeakers with Mackie Active electronics, the SRM Series delivered superior sound, performance, and affordability‚¬and were a true breakthrough in live sound technology. They fast became the most popular and relied upon Active loudspeakers in the world, launching a full-on movement in live sound.

Now, thanks to the all-new SRMv2 Series Portable Active Loudspeakers, live sound is being rocked by a new movement. Featuring new powerful Class-D Fast Recovery amplifiers, with an ultra-efficient, heat-minimizing switching power supply, the SRMv2 loudspeakers are made to be loud and stay cool‚¬even when driven at top volume, all night long. Plus, with all new transducers, including a neodymium woofer with 3-inch voice coil and heat-treated titanium compression driver, the SRMv2s deliver even more punch and clarity than the original SRM loudspeakers. Bringing whole new meaning to the word ‚¬Å“portable,‚¬ the SRMv2 loudspeakers are more lightweight than their predecessors, too‚¬the SRM450v2 weighs 11 pounds less, and the SRM350v2 weighs 6 pounds less.

So get the best-sounding, best-performing portable loudspeakers available‚¬the SRM450v2, or the ultra-compact SRM350v2‚¬and join in the new movement.

The ‚¬Å“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 ‚¬Å“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‚¬and trumps it‚¬to deliver sound that makes any venue seem like a well-tuned studio.

Ultra-Wide Dispersion
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. To those of you whose eyes just glazed over, let's just tell you what it does‚¬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 substance‚¬they just don't have it in ‚¬Ëœem 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 Mackie has 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.

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 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.

Built-in Protection Circuitry for Long Life
Mackie knows that their Active loudspeakers are pushed hard‚¬often to, or beyond, the limit. That's why they 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 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.

Versatile, Portable, Tough‚¬And They Look Good, Too
When designing the SRM450v2, Mackie considered every angle. From every angle is just how you can position it, too‚¬pole-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, it's the most versatile portable Active loudspeaker around. And now moving it into place is easier than ever. Weighing in at about 40 pounds‚¬11 pounds lighter than the original SRM450‚¬you'll 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 cabinet‚¬now in a tasty hue of Midnight Blue. So not only do you get a portable loudspeaker that sounds phenomenal, you get one that's tough and portable for the road, and handsome enough for the show.
