Mackie Thump18Sv4 18-Inch 1400W Professional Powered Subwoofer Bundle with Custom-Fitted Slip Cover — 132 dB SPL 25 Hz Class-D PA Subwoofer for Mobile DJ, Live Band, Wedding, and Club Sound Systems

18-INCH POWERED PA SUBWOOFER BUNDLE — 1400W SUB PLUS CUSTOM-FIT SLIP COVER: A bare subwoofer gigs unprotected and stores exposed to dust and scuffs. This bundle includes the Mackie Thump18Sv4 18-inch powered subwoofer and a custom-fitted nylon slip cover cut for this exact cabinet. Mobile DJs, live bands, wedding and event pros, and venue operators — roll in protected, plug in, and feel the floor move from the first track.

POWERED SUBWOOFER WITH 132 DB SPL AND 25 HZ EXTENSION: Built for mobile DJs, gigging bands, and event sound pros, the Thump18Sv4 pairs a 1400W Class-D amplifier with an 18-inch woofer for floor-shaking 132 dB output and 25 Hz low end you feel as much as hear. Punchy kicks, deep basslines, full-range sound. Plug in and feel it.

FOUR HIGH-PASS MODES FOR DJ SETS, LIVE BANDS, AND PA INTEGRATION: Match the crossover to your speakers without guesswork. Thump 12, Thump 15, and Thump GO modes auto-tune for matching Mackie loudspeakers, while Variable mode sets the crossover by hand for any PA. A 1.4 ms alignment delay in every mode keeps the sub phase-locked with the tops. Tight low end, every venue.

SCALABLE XLR I/O AND M20 POLE MOUNT FOR A GROWING RIG: Stereo XLR inputs take a DJ controller or mixer; stereo high-pass outputs feed your tops and full-range outputs chain a second sub for bigger rooms. A phase switch, variable gain, and stereo or mono summing dial it in. The M20 socket accepts the SPM400 pole to stack a top above the sub. One sub, room to grow.

CUSTOM-FITTED NYLON SLIP COVER WITH SIDE HANDLE OPENINGS: The included cover is cut for the exact Thump18Sv4 cabinet in durable nylon, with openings placed over the sub's built-in side handles. Carry, load, and unload with the cover still on — protection during the moment gear takes its worst knocks. Off the truck, it folds flat into a gig bag.
