Description
Thanks to the Mackie SRM450 v2 speaker's all-new design”from adding new amps and transducers to a new lightweight power supply”the SRM450 v2 surpasses the performance of the original SRM450 to deliver pure studio monitor sound at more powerful, full-on loudspeaker levels. Mackie has also managed to keep the SRM450 v2 affordable for musicians despite a complete redesign from the inside out.
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 2 years of extensive research and development, the first Mackie Sound Reinforcement Monitor was born”a loudspeaker that truly lived up to its name. The Mackie SRM450 v2 continues the SRM450's tradition of studio monitor sound quality delivering sound that makes any venue seem like a well-tuned studio.
Ultrawide Dispersion
Undoubtedly you've been to a show where the sound is all over the map. For instance, stand in front of the band and 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 Mackie SRM450 v2 loudspeakers are onstage, 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 Mackie SRM450 v2 speaker'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 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 that chest-pounding punch. But the SRM450 v2 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 SRM450 v2's servo feedback technology combined with its all-new neodymium woofer and 3" voice coil.
Based on Mackie's award-winning HR824mk2 studio monitor technology, the servo feedback damping electronic circuit within the Mackie SRM450 v2 locks the woofer in place with the positive and negative outputs of the amplifier. This creates a solid, direct-coupling that allows the SRM450 v2 to deliver extremely deep bass from a small cabinet. The new neodymium woofer's magnet is lighter in mass, therefore faster than ceramics, giving the SRM450 v2's bass more punch. The new longer 3" 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 SRM450 v2 operates with incredible efficiency, and delivers much more power and clarity. With this Class D Fast Recovery amplification, the SRM450 v2 handles maximum volume”and associated heat”with ease, so there's no unwanted noise or thermal problems. Even after hours of sustained use at near-peak levels, your sound remains clean and your SRM450 v2 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 SRM450 v2, 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 is completely plug-and-play”no EQ needed.
Built-In Protection Circuitry for Long Life
Active loudspeakers are pushed hard, often to, or beyond the limit. That's why Mackie built reliable protection circuitry into every unit. The SRM450 v2 employs a built-in limiter for less distortion at peak levels, and an automatic sliding high-pass filter to give you that little bit of extra volume when the crowd demands more. Thanks to the advanced technology of its power supply and Class D amp topology, the SRM450 v2 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 a longer life.
Versatile, Portable, Tough
When designing the SRM450 v2, Mackie considered every angle. You can still achieve great sound whether you polemount 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 one of the most versatile portable active loudspeakers around. Moving it into place is easier than ever too. Weighing in at about 40 lb.”11 lb. lighter than the original SRM450”you'll have plenty of strength left over to play after loading in. Plus, the SRM450 v2 retains its rugged, Mackie built-like-a-tank durability, thanks to the polypropylene cabinet.

The Standard of its class
Ill start by saying - I used to have a pair of JBL EONs. There is no question in my mind - or the mind of most other professionals that the SRM450s are the way to go. The EONs sounded like tin cans compared to the Mackies and even for a 15" woofer the EONs cant keep up with the low end response of the SRM450s. Don't take my word for it - ask someone with experience and they will absolutely tell you SRM450s all the way. Has any major club ever had EONs installed? No. Are SRM450s in major clubs? Yes. The build quality of these babies rivals that of an Abrams tank. The max volume of these blows anything in the price range out of the water. Can they be a bit harsh at higher volumes? sure. But so will almost anything. Save yourself the hassle of looking for something just because of an orange logo and go with the true industry standard - SRM450s.

Think Twice about these (Recent history of issues).
I had just bought a pair of Mackie SRM450 V2's for monitors (Using QSC K12's for mains). 1st time I used them (in practice to test them out), one of them had an intermittent 'motor' noise, like someone was using a drill near by. I turned the volume down, unplugged the input (so, it was power only), the noise still occurred intermittently. I figured I'd exchange the bad one for a new one .... I brought the one speaker back to GC (yep, the problem occurred at the store also). At the same time one other guy was in the store returning his for the same reason. Some other guy walked up and said he had problems with his Mackies, and one of the employees (in a different section of the store) had gone through at least two speakers with various issues (within the first month, but he's still using Mackies). Greg Mackie must be upset that his name is still on this product, since the quality control doesn't seem to exist as it did when he owned the company. Two other friends that I've talked to, that have been using the SRM-350's with their bands and they have had to exchange theirs (or pay to get them repaired). Mackie support isn't what it once was either (now that Greg is no longer in charge). Since this was clearly a defective product, I returned both Mackies and spent the extra money for a 2nd pair of QSC K12's ... Which to my ears sound better anyway (your taste may be different, but I've been doing sound for a lot of years, QSC is what the pros use (in an array)). Looking at the schematics, components and design, there's no contest, QSC is a much better built product! I am VERY disappointed in Mackie these days. I've been using Mackie products since the original 1604 mixer came out (in the 1980's), they are nowhere near what they used to be in reliability or service. It seems to be hit or miss if you are going to get a 'good' pair or not, and if they'll stay reliable. I can't accept having unreliable equipment on a job, thus, I am forced to give a negative review on the SRM's.

These things crank, sound clean and I've yet to make them clip. And they're built to withstand a hit from a Howitzer. Everything I could possibly have asked for.
Incredible sound in a medium cabinet
submitted14 years ago
byLarry Brown
fromHouston, TX
Construction: These things are built tough for the road. The side handles make them easy to handle for simple carry or for pole mount application. There is a "handle" on top of the of the cabinet which is neat and adds an alternate option to carry. Lightweight for a speaker in it's class. While the XLR and IEC cables fit snug, it would be nice if Mackie included a safety clasp of sorts (similiar to Yamaha). Sound/quality/ease of use: The sound from this cabinet it incredible. Warm and feels the room. I had to change out a cable during a performance and was able to supplement the sound with one speaker while I swapped cables. Something to be said about the 90 degree dispersion. Do they thump....yes indeed! Do NOT let the 12" woofer fool you. If sounds better than many 15" woofer. Tight, low end bass, with a contour button to enhance bottom end. This is a true plug and play speaker. What would make them better: an integrated EQ - that simple. I've ran these straight thru my mixer and EQ'd them there just fine. Used them with my BBE Maximizer, ever better. I love JBL's and still went with Mackie. So far, so good! If you want to splurg and can, go ahead with the QSC or the other top-shelf powered speakers. If not, give these Mackie's a try. If it's not what you want, return them in 30 days. I heard they have a hiss: that's true..the have a HP hiss, but what more can you expect from a live performance speaker. This is NOT your studio monitor. The hiss is undetected during a show.

Best speakers I've ever used

byDj Live
fromSan Jose, CA
I purchased a pair of these probably like 1.5ys ago and I have never had an issue with these speakers. I have done High School Dances in Gyms, weddings, house parties, etc. Their very easy to setup, I choose the XLR to Quarter Inch Input to my Rane 56 Quarter Inch Master. The power on these are great and sound crispy clean. I do advise to maybe invest in a carrying bag to keep them scratch free when moving them around. Other than that, if you have a pair of these and some lows to complement the sound, you have a great setup for almost any type of event. Mackie is a very good brand!
