Mackie SRM450 V3 12" 1000W Powered Loudspeaker.

Legendary. Mackie's SRM series has proven itself time and time again. And now with the Mackie SRM450 V3, you can take your sound even further.

Unmatched performance with phenomenal sound quality. A powerful 1000W amp section drives the SRM450's custom high-output transducers to deliver that signature SRM sound. Experience it all the way it was intended with High-Definition Audio processing, including patented acoustic correction algorithms and a precision 2-way crossover.

The SRM450 is as flexible as it is powerful. An integrated 2-channel mixer with dual Wide-Z inputs lets you hook up almost any sound source with ease. Plug your mic, instrument, media player, or other devices in, and take advantage of ultra-wide gain ranges to dial in your sound. And with four selectable speaker modes, you can optimise your sound for almost any application.

That SRM sound... But better

Renowned the world over. The SRM series has achieved legendary status in the world of PA speakers. After proving themselves time after time, SRM loudspeakers have become the go-to choice for DJs, bands, singer/songwriters and more. Combining phenomenal power, intuitive operation, and outstanding flexibility, Mackie's SRM series can handle anything you throw at it. And now it's had an upgrade...

Experience 'the best-sounding SRM ever' with a plethora of intelligent features. Patented acoustic correction algorithms ensure that every aspect of your sound is delivered the way it deserves to be, whilst a precision 2-way crossover provides smooth integration with the rest of your system.

SRM350 and SRM450 loudspeakers also boast driver time alignment and phase correction. What this does is simply delay the sound from one or more of the drivers to ensure that the transient response remains accurate and impactful. Your sound stays tight and powerful, whilst your speaker's directivity remains consistent.

A pounding heart

At the centre of the SRM450's high-output design, you'll find a powerful 1000W amplifier section driving the custom 12'' LF woofer and 1.4'' compression driver. The amp is loaded with Mackie's Smart Protect™ DSP, providing intelligent protection to ensure that no matter how hard you push your speaker, it can perform reliably and safely.

Hook it up

It doesn't matter what it is. The SRM450's integrated 2-channel mixer will let you connect it. Microphones, instruments, media players, and more. They'll all work seamlessly thanks to Mackie's intelligent Wide-Z™ inputs and ultra-wide gain ranges. Plus, a handy XLR thru connector lets you send your signal out to other speakers. You can choose to send the entire mix, or just channel 1 with the push of a button.

There are also some intuitive sound tools built in for optimising your sound. Four different speaker modes let you get the most out of your speaker for your current application.

PA Speaker mode offers full-range performance, providing mid-range clarity to help vocals cut through with ease.

DJ Speaker mode adds a bit more bass and treble emphasis, whilst holding back the mids ever so slightly, making it ideal for music playback.

Soloist Speaker mode rolls off the low frequencies to prevent unwanted thumps, whilst adding a boost to the mids and highs for that extra sparkle in your sound.

And Monitor Speaker mode rolls off the lows, and attenuates your signal around 2kHz, providing maximum gain before feedback for hassle-free stage monitoring.

Finally, you can use the integrated Automatic Feedback Destroyer to keep your signal clean and clear. All it takes is a single button push, and the SRM450 will do the rest. No more nasty feedback ruining your performance.

Worried you'll break it?

Don't be. Because you won't. Mackie is renowned for their 'Built-Like-A-Tank' construction, and every SRM loudspeaker is built that way. Premium components, ultra-rugged cabinets, and intelligent protection technology keep your loudspeakers going. Night after night, year after year.
