Mackie SRT215 Active Loudspeaker

Mackie SRT215 — 1600W Professional Powered Loudspeaker

The Mackie SRT215 is a 15-inch 1600W professional powered loudspeaker for front-of-house, stage monitoring and installed sound in clubs, houses of worship and performance spaces. A 1600W Class-D amplifier drives a 15" woofer and 1.4" polymer compression driver through a Sym-X Horn, delivering full-range response from 42 Hz to 20 kHz at up to 133 dB SPL. The SRT215 is the right choice for bands, DJs and venues who need one box that handles main PA, monitor duty and Bluetooth playback without external racks.

Advanced Impulse DSP and Sym-X Horn

Mackie's Advanced Impulse DSP uses FIR filtering to measure and reverse the frequency-response and time-domain anomalies each transducer introduces, so the whole room becomes the sweet spot rather than just a narrow seat in front of the speaker. The custom Sym-X Horn is loaded below the HF driver's LF capability, allowing the compression driver to operate at near-maximum efficiency with a symmetrical, flat response at the crossover. Transparent system protection applies multi-band compression to problem frequencies rather than pulling down the whole output.

Key Specs and Player-Facing Parameters

The 1600W amp, 133 dB peak SPL and 90° x 60° coverage mean a pair can cover an audience of around 250, while 42 Hz low-end extension keeps kick drums and bass guitar full without a sub in smaller rooms.

• Amplifier Power: 1600 W Class-D — 1400 W to the woofer, 200 W to the HF driver
• Frequency Response: 42 Hz – 20 kHz — full-range output reaching down to kick-drum territory
• Max SPL: 133 dB — enough volume for small-to-mid venues and mobile DJ gigs
• Inputs: 2x Combo XLR-1/4" + 3.5 mm TRS aux + Bluetooth — mic, instrument and backing tracks from one box
• Built-in Mixer: SRT Mix Control 4-channel digital mixer — 10 user presets, voicing modes, alignment delay up to 30 m
• Wireless Control: SRT Connect iOS/Android app — EQ, levels, presets and linking from the audience
• Weight: 16.8 kg / 37.1 lb — light enough for one-person load-in

Who the Mackie SRT215 Is Built For

The SRT215 is aimed at working bands, mobile DJs, singer/songwriters, houses of worship and small-to-mid venue operators who want one powered speaker that can do main PA, floor monitor and Bluetooth playback without external racks. Solo performers can plug a mic into channel one, a guitar or keyboard into channel two via Hi-Z, and stream backing tracks over Bluetooth — all shaped through the built-in voicing modes and saved as one of 10 user presets. The dual-angle pole mount, M10 flypoints and dual-angled cabinet mean the same box works on a tripod, flown, or angled back as a wedge.
