Mackie SRM450v3 12-Inch 1000W Powered PA Loudspeaker with DSP Modes

Mackie SRM450v3: Big-Room Output From a Legendary Portable

The Mackie SRM450v3 is a 1000W 12-inch powered PA loudspeaker that combines custom transducers with high-definition DSP to deliver deep, high-output sound in an indestructible, portable cabinet. It carries the legacy of the most widely used portable loudspeaker ever - now with more power, a built-in 2-channel mixer, four speaker modes, and integrated fly points. When a room is too big for a 10-inch box, the SRM450v3 steps up without ever losing its road-ready simplicity.

1000 Watts With Real Low End

A 1000-watt peak Class-D low-frequency amplifier and a Class-AB high-frequency amplifier drive a 12-inch high-output woofer and a 1.4-inch titanium-dome compression driver to 128 dB peak SPL, with usable response down to 47 Hz. That extra cone area and headroom give the SRM450v3 the punch and reach a 10-inch cabinet cannot match, filling larger venues, dance floors, and outdoor events with clean, undistorted sound.

High-Definition Audio Processing Tuned by EAW

The SRM450v3 runs patented acoustic correction developed with the touring engineers at EAW, a precision 2-way crossover at 3 kHz, and driver time-alignment with phase correction. These align the low and high drivers in time and flatten the frequency response, so a compact 12-inch enclosure reproduces vocals and full-range music with the even, detailed clarity you would expect from a much larger touring system.

Four Speaker Modes, One Button

One button cycles four voicings tuned to the application. PA mode is full-range with a midrange focus for vocal intelligibility; DJ mode lifts the lows and highs with a gentle midrange tuck for music playback; Monitor mode rolls off the lows and dips around 2 kHz for maximum gain before feedback on stage; and Soloist mode strips low-end thumps and adds high-end sparkle for plug-and-play singer-songwriters.

A Complete Mixer Onboard

Two Mackie Wide-Z combo inputs each accept a microphone, an instrument, or a line-level source and dial in the right gain with one knob, so the SRM450v3 handles a dynamic mic, an acoustic guitar, or a mixer output with equal ease. A stereo RCA input brings in backing tracks, and a balanced XLR thru output feeds a second cabinet or subwoofer - a full front end that lets a solo act or small band run without an external mixer.

Fly It, Pole It, or Monitor With It

Three integrated M10 x 1.5 mounting points accept forged-shoulder eyebolts, so the SRM450v3 hangs safely for permanent installs in clubs and worship spaces. The same cabinet drops onto a 35 mm speaker pole, stands on the floor, or tilts back 40 degrees to serve as a stage monitor - and an automatic feedback destroyer with Smart Protect DSP keeps every one of those configurations quiet and protected.

Who the SRM450v3 Is For

Mobile sound companies, wedding and event DJs, houses of worship, and rental houses choose the SRM450v3 when they need bigger output and lower reach than a 10-inch box delivers, yet still want a speaker two people can load in a single trip. At 37 pounds in a rugged polypropylene cabinet, it is the high-output member of a live-sound legend, ready for the next gig straight out of the case.
