Mackie THUMP15SV4 15" Powered Subwoofer

The Mackie THUMP15SV4 is a 15” powered subwoofer engineered to anchor DJ and live sound systems with commanding low–end authority. Built on decades of Mackie's professional audio expertise, it pairs a 1400W Class–D amplifier with a high–performance woofer to deliver 132 dB maximum SPL and frequency response down to 27 Hz–floor–shaking bass that translates kick drums and basslines with genuine impact in club and venue settings.

Connectivity and integration make the THUMP15SV4 a natural fit in modern DJ rigs. Stereo XLR inputs accept signals from controllers, mixers, or audio interfaces, whilst dedicated high–pass outputs feed connected loudspeakers with selectable crossover modes: Thump 12 (140 Hz), Thump 15 (110 Hz), Thump GO (150 Hz), or Variable for manual tuning to any cabinet. All modes include 1.4 ms alignment delay to keep phase tight. Construction weighs 26 kg with built–in handles and an M20 threaded top for pole mounting via the SPM400 (sold separately), allowing compact stacking in confined booth or stage spaces without sacrificing output.

Practical controls support both solo and dual–subwoofer configurations. Phase invert, defeatable LED, stereo or mono summing, and variable level control (–Muted to +6 dB) enable precise tuning to room acoustics and system voicing. Full–range XLR outputs allow daisy–chaining additional subs for larger venues, making the THUMP15SV4 scalable across small clubs, larger events, and fixed installations alike.
