Mackie Thump 15 V4 Active PA Speaker Package With Thump 18S Subs, Poles & Cables
The ultimate high-power PA stack bundle — two Mackie Thump 15 V4 active loudspeakers, two Thump 18S V4 active subwoofers, two SPM400 threaded speaker poles and four 3m Stagecore XLR cables, delivering maximum bass depth and output for larger venues and demanding live sound applications.
This bundle steps up from the Thump 12 V4 package with the larger Thump 15 V4 loudspeakers and Thump 18S V4 subwoofers, pairing two of Mackie's most powerful and capable 15" active loudspeakers with two of the deepest-reaching subwoofers in the Thump V4 range — creating two complete, self-contained high-power PA stacks. By mounting each Thump 15 V4 above a Thump 18S V4 subwoofer via the SPM400 pole, each stack delivers full-range sound reaching down to 25Hz from a single compact floor footprint — ideal for medium to large venues, mobile DJs, gigging bands and events demanding serious low-end impact.
Thump 15 V4 — Maximum Power & Depth
Each Thump 15 V4 delivers 1400W Class-D amplification, 130dB maximum SPL and a remarkably deep 34Hz low-frequency response — one decibel louder and five Hertz deeper than the Thump 12 V4. SoundCheck DSP™ voicing modes (Flat, DJ, Live and Wedge), Feedback Eliminator, Music Ducking, Outdoor Mode, Bluetooth streaming and Thump Connect 2 app control are all included, alongside the same versatile built-in mixer and XLR mix output.
Thump 18S V4 — Floor-Shaking Sub-Bass
Each Thump 18S V4 subwoofer delivers 1400W Class-D amplification, 132dB maximum SPL and an exceptional 25Hz low-frequency response — two Hertz deeper than the Thump 15S V4 — with four selectable high-pass modes including a dedicated Thump 15 mode (110Hz crossover) with 1.4ms alignment delay for seamless, phase-coherent integration with the Thump 15 V4 loudspeakers.
SPM400 Poles & Stagecore XLR Cables
Two Mackie SPM400 M20 threaded speaker poles mount each Thump 15 V4 directly above a Thump 18S V4 subwoofer for a clean, compact all-in-one PA stack. Four Stagecore 3m black XLR to XLR cables — featuring a hard-wearing sheath, solid metal connectors and oxygen-free copper conductors for clean, reliable audio signal transmission — provide all the connections needed to link the complete system together. Each cable is RoHS compliant, supplied with a hook and loop tie for neat storage and backed by a limited lifetime warranty.
