Special Order

Beef Up Your Rig with 1,600 Watts of Thunderous Bass!

When nothing but an epic blast of bass will do, turn to the intense low end of Mackie's SRM2850 powered subwoofer. Pushing a pair of beefy 18" woofers with a 1,600-watt amp, the SRM2850 delivers 1,600 watts of huge-sounding bass through a custom-designed 18" woofer. It's easy to dial in great sound on the fly because the SRM2850 has presets intended specifically for use with other Mackie SRM series loudspeakers, along with a variable digital crossover so you can match it with any other system as well. If you need a powerful, road-ready subwoofer, then the Mackie SRM2850 is an exceptionally good choice.

Mackie SRM2850 Powered Subwoofer at a Glance:
  • A flexible but easy-to-use subwoofer
  • Smart DSP enhances your sound and saves you time
  • Built tough to withstand the rigors of the road
A flexible but easy-to-use subwoofer

If you play different rooms of different sizes, you'll love the flexibility of the Mackie SRM2850. And no matter what your system looks like on any given night, the SRM2850 is easy to set up. If you're using it to reinforce other Mackie SRM loudspeakers, you'll find presets to perfectly match your SRM650 or SRM750 speakers. There's also a variable crossover onboard, which lets you fit the SRM2850 into the mix. And because it has dual full-range outputs in addition to dual highpassed outputs, you can easily integrate a single SRM2850 into virtually any stereo PA system.

Smart DSP enhances your sound and saves you time

The Mackie SRM2850 powered subwoofer is smart. It has built-in Smart Protect DSP to protect the amp/drivers from signal clipping and crossover presets for use with Mackie's SRM series speakers. These built-in options make setting up the SRM2850 a breeze at any venue. The SRM2850's rugged all-wood, internally braced cabinet uses a tough 18-gauge steel grille to protect its speaker from damage.

Built tough to withstand the rigors of the road

Mackie didn't just select 18mm poplar plywood because it sounds good - they selected it because it holds up to serious abuse. And that's exactly what any touring PA system is up against, as your speakers get tossed into trucks and hauled from venue to venue. Even if you're using your SRM2850 for a permanent installation, the heavy-weight 18-gauge grille will more than stand up to the occasional "oops" moment when a stagehand knocks over a stand or cuts a corner too closely with a cart. It's all part of the Built-Like-A-Tank philosophy that keeps Sweetwater customers (and a fair number of us employees) choosing Mackie gear time and again.

Mackie SRM2850 Powered Subwoofer Features:
  • 1,600-watt powered subwoofer with amazingly high size/output ratio
  • Dual 18" LF woofers offer rich, solid low-frequency reinforcement
  • Smart Protect DSP prevents runaway signal from damaging your speakers
  • 2 full-range outputs allow you to easily connect side-fill speakers
  • 2 highpassed outputs for connecting to full-range mains
  • Built-in crossover presets specifically for Mackie SRM650 and SRM750 loudspeakers
  • Pole mount allows you to attach a speaker pole for main speaker
  • Stackable for easy storage, transport, and arrangement onstage
The Mackie SRM2850 powered sub delivers 1,600 watts of foundation-shaking bass!
