Mackie SRM450 V2 12 in 2 Way Powered PA Speaker

Discontinued
Mackie SRM-450-V2 2-Way Active Loudspeaker Black

Live sound sometimes seems like a wild, uncaged animal-very hard to control. With the SRM Series Portable Active Loudspeakers, Mackie came up with the technology to help tame the beast, so you could focus on your performance, instead of being distracted by constant EQ and level tweaks. Now, with the SRM450v2, live sound is whipped completely into submission, giving you more control over your shows than ever. 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. Mackie kept it affordable, too-even though the SRM450v2 is a complete redesign from inside out, it retained a musician-friendly price tag. With the SRM450v2, live never sounded so good ...or behaved so well.

Want to know more? Then read on.

Stunning Bass via Servo Feedback Controlled, All New Lightweight Woofer 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. And 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.

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 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. Learn what's inside.

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 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, 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 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. 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.

    Yep, I fell for the JBL EONs at first - thought - wow they have a 15" woofer and they have that JBL tag on them. Heard them in my local store at low volume and thought they were it. Took em home and said wow - these sound like tin cans and they clip worse than a hi-fi system. Bought the SRM450s and have never looked back. The build quality is like a tank and the max SPL is absolutely the best in its class. Everyone I know in the industry undoubtedly recommends these over EONs and I have to say my only regret is not getting them sooner. Dont be fooled by the 12" woofer either - these things have a punch that blows away lots of 15" woofers.
    Highs can be a bit harsh when pushed to the limit but they more than make up for it with their price tag and max SPL. Pick up a pair of these and enjoy owning and using an industry standard.

    One of my DJ buddies bought these, & when I attended one of his bar gigs (small venue, under 75 people) I noticed his speakers distorted way too easily. His Denon mc6000 levels were only at 50-60%. His bass levels distorted anything above +2 (think 1pm setting). We checked various settings between his deck & speakers but in the end there was very little play room soundwise, at least for that venue. For what they're priced, i'd pay an extra $200 and get something that's solid...

      I use this product numerous times and they always perform well. They are lightweight, and have a a great design. They get very loud before clipping. Though, when pushed at high volumes they sound very harsh, they bass cannot compensate for the amount of highs coming through the speaker.

          Comments about Mackie SRM450 V2 12 in 2 Way Powered PA Speaker:

          Recently moved to active speakers. My 1st set was the Mackie TH15A (Thumps) and I liked them but found that they didn't really get as loud as I liked, so I started researching for a second pair and I chose the SRM 450v2 and they blew me away. The were more powerful and sounded great, The only thing I wish they had on them was a 3 band EQ but the "contour" setting works with a similar setting that I would use on my EQ. Took them out for the 1st time this past weekend to a school dance in a huge gym and they filled place wonderfully. Another feature I liked was the ability to attach a light bar to the top which allows me to run a basic small light show without having to carry another pole (which for a mobile DJ that matters. Eventually I'll add a sub to my system but I'm more than happy with these speakers as they are now my main's and the Thumps are my backups.

                Comments about Mackie SRM450 V2 12 in 2 Way Powered PA Speaker:

                Yep, I fell for the JBL EONs at first - thought - wow they have a 15" woofer and they have that JBL tag on them. Heard them in my local store at low volume and thought they were it. Took em home and said wow - these sound like tin cans and they clip worse than a hi-fi system. Bought the SRM450s and have never looked back. The build quality is like a tank and the max SPL is absolutely the best in its class. Everyone I know in the industry undoubtedly recommends these over EONs and I have to say my only regret is not getting them sooner. Dont be fooled by the 12" woofer either - these things have a punch that blows away lots of 15" woofers.
                Highs can be a bit harsh when pushed to the limit but they more than make up for it with their price tag and max SPL. Pick up a pair of these and enjoy owning and using an industry standard.

                    A:

                    That means the speaker has an internal amp for both the woofer and the tweeter.

                    Since this product is sold in the US it is shipped 110v. To switch it to 230v you would need to look into it with Mackie.

                    These are some great speakers by Mackie. Unfortunately, the speakers do not come with cables

                    Yes, it has a switching power controller. You will need the correct power cord terminating in IEC to fit the mackie receptacle. Please use our International checkout option on the web ONLY.
