Mackie Thump12v4 Pair 1400W Powered PA Speakers Bundle with 2 Thump15Sv4 15-Inch Subwoofers and 2 SPM400 Poles — 129 dB Stereo Sub Stack PA for Mobile DJ, Bands, Weddings, Large Venues

STEREO TWO-STACK PA SYSTEM - TWO POWERED TOPS, TWO POWERED SUBWOOFERS, AND TWO POLES: A single stack covers a small room, but a wide stage or packed reception needs sound on both sides and double the low end. This bundle pairs two Mackie Thump12v4 12-inch powered tops, two Thump15Sv4 15-inch powered subwoofers, and two SPM400 steel poles into two complete stacks. Mobile DJs booking ballrooms, gigging bands on wider stages, and wedding hosts filling large halls - set one stack per side and run the room in stereo today.

STEREO POWERED PA SPEAKERS WITH SOUNDCHECK DSP AND DUAL ONBOARD MIXERS: Built for mobile DJs, live bands, houses of worship, and event production crews, the two Thump12v4 tops drive 1400W peak each through a 12-inch woofer and 1-inch compression tweeter to 129 dB SPL per side, with one-button Flat, DJ, Live, and Wedge voicing and a 2-channel combo XLR/TRS mixer on each top. Set one left, one right, and play in stereo.

WIRELESS STEREO LINKING AND APP CONTROL FOR DJ SETS, WEDDINGS, AND LARGE EVENTS: The two Thump12v4 tops link wirelessly so the left speaker carries the left channel and the right carries the right with no signal cable across the stage. The Thump Connect 2 app controls EQ, voicing, Feedback Eliminator, and Music Ducking on both speakers from the floor. Walk the room while you dial the mix.

FEEDBACK ELIMINATOR, MUSIC DUCKING, AND OUTDOOR MODE ON BOTH TOPS: Onboard DSP on each Thump12v4 catches feedback before it rings, dips music automatically under mic announcements, and adds an Outdoor Mode voicing for open-air events. Either top also flips into a floor-monitor wedge for stage foldback. Two speakers, every room, indoor or out.

TWO THUMP15SV4 15-INCH SUBWOOFERS - 27 HZ LOW END AND TWICE THE AIR MOVED: The pair of 1400W 15-inch powered subs reaches 27 Hz at 132 dB peak each, so kick and bass stay felt across a large floor. Thump 12, Thump 15, Thump GO, and Variable high-pass modes match the crossover to the tops, and a 1.4 ms alignment delay keeps every sub and top phase-aligned so kicks land tight, not smeared.
