Mackie Thump 115S Active Subwoofer

Mackie Thump 115S — 1400W Active Subwoofer for Live Sound Systems

The Mackie Thump 115S is a 15" powered subwoofer built to anchor any Thump PA rig with chest-pounding low end. A 1400W Class-D amplifier drives the 15" woofer to 131 dB max SPL, delivering clean bass at club volume. This model suits mobile DJs, bands, and houses of worship needing road-ready low-frequency reinforcement. Integrated handles and Built-Like-A-Tank construction make transport easy.

Three Voicing Modes and Variable Crossover for System Tuning

Unlike most subwoofers in this class, this unit ships with three voicing presets that shape low-end character without external processing. Flat delivers a natural balance, Deep emphasizes ultra-low frequencies for dance and electronic music, while Punch prioritizes maximum output for rock bands. A variable crossover sets the handoff between sub and full-range tops.

Amplifier Power and Output Specifications

Headroom matters when a sub keeps up with a full band or packed dance floor. This Class-D amplifier delivers sustained power, and the 131 dB max SPL lets the cabinet hold its own next to a 15" top.

• Amplifier Power: 1400 W Class-D — club-level headroom
• Max SPL: 131 dB — enough for mid-sized venues
• Frequency response reaches 36 Hz, providing deep sub-bass for your kick and bass tracks.

Driver and Cabinet Configuration

The 15" high-performance woofer sits in a rugged ported enclosure tuned for low-frequency extension. At 23.72 kg, the cabinet is light enough for one operator.

• LF Driver: 15" high-performance woofer — handles kick, bass, and sub content
• Cabinet Weight: 23.72 kg — manageable for one-person transport
• M20-threaded pole mount accepts standard speaker poles.

Inputs, Outputs, and System Integration

Stereo XLR inputs feed the internal DSP, while parallel full-range and high-pass XLR outputs route signal to tops or additional subs without external crossovers. Mono/stereo summing handles single or dual subwoofer deployments.

• Stereo XLR inputs are provided to accept mixer outputs or tops loop-through.
• Full-range and high-pass XLR outputs run in parallel for flexible routing.
• Controls: Variable crossover, polarity invert, level (-6 to +6 dBu), mono/stereo summing
