People go to a live show to feel the power of the music. The 18" 2000W DRM18S will deliver the power, they'll feel it, and the experience will be remembered.With a 2000W Class D amplifier onboard you'll have enough headroom to pound the concert or dance floor. Plus, Mackie has included what they call Power Factor Correction which assures stable performance even with unstable house power. This means you'll be enjoying consistent, powerful, undistorted bass until the show is over. Speaker protection circuitry is also built-in, just in case you push the fader to 11.The DRM Control Dashboard gives you control over critical performance parameters and a window into system performance from its high-resolution full-color display. You'll be able to save up to 6 application or venue specific presets with crossover frequency points and alignment delay to save time dialing the system in.Of course, you get Mackie's "Built-Like-A-Tank" design that will stand up to whatever the road throws at it along with their standard versatility. The DRM18S can be free-standing, pole-mounted or flown via an optional FB100 Fly Bar with FKDRM18S Flyware Kit (both sold separately).Make sure they know what hit em', make sure it's the DRM18S.Mackie DRM18S Features:High-excursion woofer offers increased bass response, low distortion, and professional reliability to withstand the most demanding applicationsAcoustically designed with ample internal volume and precision tuned port sizing to naturally deliver the bass you need with minimal distortionParallel SpeakON inputsRoad-worthy 18mm plywood construction and internal bracing offers optimal acoustic performance and reliabilityTouring-grade textured cabinet coatingPowder-coated heavy gauge steel grilleM20 threaded pole attachment for use with DRM Series loudspeakers and other pole mountable speakersFlyable via optional FB100 Fly Bar and FKDRM18S Flyware KitOptional SP260 Loudspeaker Processor provides custom EQ curves and crossovers for your DRM Passive SystemMackie DRM18S Specifications:Active SubwooferPower handling (continuous/program/peak): 500W / 1000W / 2000WWeight: 90 lbs (40.8 kg) Mackie DRM18S 18 Active Subwoofer, 2000W.
