Mackie Thump 15S V4 15" 1400W Powered PA Subwoofer

Powerful 1400W 15" Powered Subwoofer With 132dB Max SPL, 27Hz Low Frequency Response & Selectable High Pass Modes – The Perfect Complement To Your Thump V4 System – Mackie Thump15S V4.

The Mackie Thump15SV4 is a professional 1400W powered subwoofer combining a 15" high-performance woofer with a Class-D amplifier to deliver a massive 132dB maximum SPL and a floor-shaking 27Hz low frequency response — making it the most powerful and capable subwoofer in the Thump V4 range. Designed as the perfect complement to the Thump V4 loudspeaker series, it brings complex basslines, punchy kicks and the deep low-end foundation that transforms a good PA system into a truly impactful one. Built-Like-A-Tank™ yet lightweight with built-in handles for easy loading and transport, it is a genuine workhorse subwoofer for gigging professionals who need powerful, reliable bass night after night.

A key feature of the Thump15SV4 is its four selectable high pass modes, each optimised for a specific Thump loudspeaker pairing — Thump 12 (140Hz crossover), Thump 15 (110Hz crossover) and Thump GO (150Hz crossover) — with a Variable mode for setting the crossover manually to match any loudspeaker. All modes include a 1.4ms alignment delay for phase-coherent system integration. Stereo XLR inputs accept signals from DJ controllers, mixers and other sources, stereo high-pass XLR outputs feed connected loudspeakers with the correctly filtered signal, and stereo full-range XLR outputs allow the unaltered signal to be chained to an additional subwoofer. Phase invert, stereo or mono summing, variable level control and a defeatable front LED provide comprehensive system configuration options, and an M20 threaded top allows the Mackie SPM400 speaker pole (sold separately) to be used to mount a Thump V4 loudspeaker directly on top for a compact, self-contained PA stack.

1400W Class-D Power & 27Hz Low Frequency Performance

The Thump15SV4 is built around a 1400W Class-D amplifier and a 15" high-performance woofer that reaches a remarkable 27Hz low frequency — well into sub-bass territory that is felt as much as heard. With a maximum SPL of 132dB, it delivers the kind of powerful, authoritative bass that gets people on the dance floor and keeps them there, whether the system is being used for DJ sets, live bands, karaoke or general PA applications. Built-Like-A-Tank™ construction ensures it can handle the demands of regular gigging, while the lightweight design and built-in handles make it manageable for a single operator.

Selectable High Pass Modes For Perfect System Integration

The Thump15SV4 takes the guesswork out of subwoofer and loudspeaker integration with four selectable high pass modes, each pre-configured with the optimal crossover frequency for a specific Thump V4 loudspeaker. Thump 12 mode sets a 140Hz crossover for Thump12V4 loudspeakers, Thump 15 mode sets a 110Hz crossover for Thump15V4 loudspeakers, and Thump GO mode sets a 150Hz crossover for Thump GO loudspeakers. All modes include a 1.4ms alignment delay for coherent phase integration between the subwoofer and loudspeakers, and Variable mode allows the crossover to be set manually for use with any third-party loudspeaker.

Versatile I/O & System Configuration Options

Stereo XLR inputs provide flexible connectivity from DJ controllers, mixers and other source equipment, while stereo high-pass XLR outputs feed connected loudspeakers with the correctly filtered signal. Stereo full-range XLR outputs pass the complete unaltered signal to a second subwoofer for expanded low-end coverage. Phase invert, stereo or mono summing for single or dual subwoofer deployment, variable level control from muted to +6dB and a defeatable front LED provide comprehensive fine-tuning capability. The M20 threaded top accommodates the Mackie SPM400 speaker pole (sold separately), allowing a Thump V4 loudspeaker to be pole-mounted directly above the subwoofer for a clean, compact and space-efficient PA stack.
