Mackie's SRM series loudspeakers are the most widely used portable loudspeakers ever. For well over a decade, musicians and sound engineers have trusted these speakers to be easy to use, boast exceptional sound quality, and be durable enough to withstand the road. The SRSM450v3 improves on their already landmark design, packing it with 1000 W of power, the widest selection of sound-enhancing DSP, and setup-friendly audio tools.

Onboard the speaker is a 2-channel mixer, giving your sound system some extra versatility. An automatic feedback destroyer instantly corrects any feedback with four incredibly narrow 1/16th octave filters, so the music never stops! There is also a unique knob where you can select your "application-specific speaker mode", a brilliant-yet-easy way to fine-tune your sound for whatever situation you're in, from a DJ mix to a full band to an acoustic duo.
