Mackie SRM-Series 1600W 18" Powered Subwoofer

The Mackie SRM1850 18" Powered Subwoofer is "Built-Like-A-Tank," delivering 1600W of intense power paired with a custom high-output woofer for powerful, chest-pounding low end performance. The professional-grade, internally-braced all-wood enclosure provides tour level roadworthiness and is front ported for maximum low-frequency extension and punch. The SRM1850 features stereo XLR inputs, full-range and high-pass outputs plus a variable digital crossover that includes presets for Mackie SRM top boxes. Mackie Smart Protect DSP is also in place to protect your investment when things get pushed a little too hard. Get the powerful low end your music demands in a rock solid subwoofer with proven Mackie performance.

Class-Leading Power
Mackie's SRM1850 subwoofer pumps 1600W of intense class-D power into a custom high-output 18'' woofer delivering chest-pounding low end performance at gig-level volumes with room to spare.

This extremely tough 18mm allwood "Built-Like-A-Tank" cabinet delivers professionalgrade road-worthiness with a durable black steel grille, textured scratch resistant black finish and front ported design for maximum low-frequency extension and punch.

Variable Crossover
Tuning your system just got easier with the integrated digital crossover and easy onetouch presets for each SRM top box. There's even variable control for matching the crossover to any loudspeaker.

System Protection
Push the mix to the limit with peace of mind. Mackie's Smart Protect DSP regulates each speaker and kicks in to protect your investment against damage when things get pushed a little too hard.

Output Connections
Chain additional loudspeakers and subwoofers together for larger audiences using the dual full-range outputs while drastically improving the midrange performance of your SRM top boxes using the high-pass outputs and built-in crossover presets.

Subwoofer Add-on
Pair the SRM1850 subwoofers with either SRM550 or SRM650 powered 2-way top boxes for a complete "plug and play" PA system. Use the pole-cup to accommodate any standard pole mount or just stack the boxes right on top. No matter what the application, Mackie's powered SRM subwoofers come standard with dual full-range and high-pass stereo XLR outputs for even the most complex connections. Plus, the onboard variable crossover can also easily integrate the SRM1850 into nearly any existing PA setup you may already have needing low-end reinforcement.
