Mackie SRM350V2 Powered Speaker

MACKIE SRM350V2 Details ^top

Sharing the same new technology that makes the SRM450v2 the breakthrough live performance powerhouse that it is, the ultra-compact SRM350v2 is perfect for when space is at a premium. The SRM350v2 whips live sound into complete submission, giving you more control over your shows than ever. Thanks to its all-new design-from adding new amps and transducers to a new switching power supply-the SRM350v2 surpasses the performance of the original SRM350 to deliver pure studio monitor sound at more powerful, full-on loudspeaker levels. It’s even more lightweight than before, making it ultra-portable. We kept it ultra-affordable, too-even though the SRM350v2 is a complete redesign from inside out, we retained the musician-friendly price tag. With the SRM350v2, live never sounded so good …or behaved so well.

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 SRM350v2 continues the SRM350’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 SRM350v2 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 SRM350v2’s wide dispersion pattern, which is achieved through its High Frequency waveguide.

Professional Grade Transducers
The SRM350v2 has sounds even better than the original, in part, because of it’s premium transducers. The new 10” neodymium woofer has less mass and quicker response providing incredibly punchy response from such a small loudspeaker. Not to mention it is much lighter than a traditional ceramic magnet based transducer. Additionally, it’s titanium compression driver provides sparkle and clarity beyond the original design keeping it’s characteristic sound in-line with it’s big brother, the SRM450v2. The acoustic gurus out at EAW spent months and months tweaking these custom designed transducers so that the SRM350v2 would deliver the best sound possible in a small format box.

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 SRM350v2 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 SRM350v2 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 SRM350v2 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. Our proven Active design does all the work for you. With our SRM350v2, 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
We know our Active loudspeakers are pushed hard-often to, or beyond, the limit. That’s why we have reliable protection circuitry built in to every one. The SRM350v2 employs a built-in limiter for less distortion at peak levels. And thanks to the advanced technology of its power supply and Class-D amp topology, the SRM350v2 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 SRM350v2, we 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 optional hanging bracket, 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 just 26 pounds-now that’s light!-you’ll have more than enough strength left over to deliver an electrifying performance after loading in. Plus, the SRM350v2 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.

Overall	5

The new SRM speakers sound great, just like the old, but are lighter weight. That s primarily because of neodymium magnets in the speakers also a lighter (and cheaper) class-D amplifier topology. They also cost A LOT more! Why? Inflation? Corporate greed? Terrorism? Yes and ignorance. Although it belongs to rare earth metals, neodymium is not rare at all. It constitutes 38 ppm of Earth s crust. In fact, NEODYMIUM IS THE SECOND MOST ABUNDANT of all rare-earth elements. So WHY is it MORE EXPENSIVE? 1- Because, school and television have stripped away all vestiges of intellectual vigor. 2- Because, greedy public corporations exploit ignorant consumers. Companies will continue to charge more for neodymium products by advertising that this is a rare earth element as if that meant neodymium should be more costly. Uninformed consumers will continue to pay extra for neodymium until they learn. Send a message by NOT buying hype. DO NOT be duped by marketing-lies. Rare Earth does NOT mean RARE! It SHOULD NOT be more expensive! Wake up! Research the facts for yourself. If you want to pay an extra 20 for 6 lbs less weight, go ahead. In doing so, you will be contributing to continued exploitation of ignorance. BTW Class-D amplifiers are NOT better in any way for the end-user. They are only cheaper to manufacture. They also are more tricky to engineer so that they perform as well as other more-robust, proven amplifier topologies. The NEW SRM speakers, SHOULD cost 10 LESS NOT 20 MORE!
