A lightweight and portable, full-range, active loudspeaker system intended for PA applications. The system provides high output, wide dispersion and low distortion. The Mackie SRM is the most widely used portable loudspeaker ever. It’s unparalleled ease-of-use, professional sound quality and indestructible portability has made it a live sound legend. Now with more power and flexibility than ever, SRM is the ultimate portable PA system.


The 1000W SRM350 and SRM450 feature modern tools like application-specific speaker modes and an automatic feedback destroyer, each with a single-button interface that gets you optimized performance in just seconds. And with the integrated 2-channel mixer, you can easily mix multiple sources. The SRM Portable Series is beyond powerful and provides an array of modern features making these the easiest to use, best sounding SRMs ever.


Manufactured from reinforced polypropylene, SRMv3 loudspeakers are suitable for musical performance, rehearsal, conference and house of worship PA applications. Two convection cooled Class-D, fast recovery amplifiers independently power the lightweight woofer and titanium compression driver. Mackie's active electronics provide phase correction, crossover, equalisation and protection circuitry.


A latching 'Timed Turnoff' button enables automatic power switching. An input signal level of -45 dBu (minimum) activates auto-on. No input signal for 3mins+ will activate the auto-off function to conserve energy. Contour and Low Cut switches allow for personalisation of the audio output. Mic/line input is via 3-pin female XLR and a pass-thru (3-pin male XLR) output enables daisy-chain connection to additional active loudspeakers
