Mackie Thump 15S V4 15" Powered Subwoofer

Mackie Thump 15S V4
The Mackie Thump 15S V4 is a powered subwoofer designed to complement the Thump V4 series of loudspeakers. Built for DJs, live performers, small venues, and mobile entertainers, it delivers deep, impactful low-end reinforcement in a portable, road-ready package. The Thump 15S V4 pairs seamlessly with full-range Thump speakers to create a complete sound system capable of filling a room with clean, powerful audio.

Powerful, Purpose-Built Bass Performance
At the heart of the Thump 15S V4 is a 15-inch woofer driven by a 1,200-watt peak Class D amplifier. This combination produces low frequencies with authority — capable of reaching down to 35 Hz — giving bass lines, kick drums, and electronic music the physical impact that full-range speakers alone cannot provide. The built-in DSP engine handles subsonic filtering and protection circuitry to ensure clean output at high SPL levels, with a maximum of 128 dB peak SPL.
Intuitive Controls and Flexible Routing
The Thump 15S V4 features an easy-to-navigate control panel with a dedicated low-pass filter, a contour switch for different bass response shapes, and a phase switch to align the sub with your main speakers. A stereo pass-through allows signal to flow from the sub to connected full-range speakers, simplifying cabling for a complete system. The crossover point is adjustable, letting users fine-tune the blend between subwoofer and tops for different room acoustics.
Durable Design Built for the Road
Mackie engineered the Thump 15S V4 with durability in mind. The cabinet features a rugged woodgrain ABS enclosure that resists scratches and bumps during transport and setup. Ergonomic handles and a compact footprint make it manageable for solo operators, while integrated pole cup mounting lets it serve double duty as a speaker stand base for Thump full-range tops. A built-in carry handle and balanced XLR I/O connectors round out a design that's clearly meant for gigging professionals.
Why We Love This
Our gear experts love the Thump 15S V4 because it delivers professional-grade low-end without the professional-grade complexity. Setup is fast — just connect your tops through the XLR pass-through, dial in the crossover, and go. The 1,200-watt amp means you're never underpowered for small to medium venues, and the flexible contour voicing helps it adapt to different genres. Its durability, integrated pole mount, and competitive performance make it a dependable workhorse for working musicians and DJs alike.
