Mackie - 18"1400W Powered Subwoofer with 2 High-Pass XLR Outputs, Voicing Modes, XLR I/O, Power Cord and Pole Mount

Add serious low-end impact to your live sound setup with the Thump118S 1400W Powered Subwoofer, a portable 18-inch active sub designed to complement full-range speakers while delivering strong bass performance for small club systems, bands, and mobile PA rigs. Its 1400W Class-D amplifier is built for reliable, consistent output, powering a high-performance 18-inch woofer with a frequency response of 30 Hz to 150 Hz and maximum SPL of 132 dB. Four application-specific voicing modes including Flat, Deep, Punch, and Variable make it easier to tailor the subwoofer to different music styles and system needs, while variable crossover control, polarity invert, variable level control, and stereo or mono summing support more flexible integration in single- or dual-subwoofer deployments. Two XLR inputs, two high-pass XLR outputs, and two full-range XLR outputs provide versatile connectivity, and practical features such as a defeatable front LED, integrated M20-threaded pole mount, built-in side handles, and included power cord make it easier to deploy, transport, and configure for demanding gig use.

• 1400W Powered Subwoofer With Strong 18-Inch Bass Output: Bring deeper, more powerful low end to your PA system with the Thump118S, a portable powered subwoofer built around a 1400W Class-D amplifier and a high-performance 18-inch woofer. Designed for live sound applications, it delivers reliable, consistent bass reinforcement for small club systems, bands, and other setups that need added low-frequency support with strong output and portability.
• Four Voicing Modes Tailor Bass For Different Applications: Adjust the subwoofer’s response more easily with four application-specific voicing modes: Flat, Deep, Punch, and Variable. Flat provides a natural balance between deep bass and overall output, Deep emphasizes ultra-low frequencies, Punch prioritizes the highest possible output level, and Variable adds more flexibility for system tuning in a range of live sound environments.
• Variable Crossover, Polarity, And Summing Add Flexibility: Fine-tune how the Thump118S integrates into your system with a variable crossover frequency, polarity invert switch, and stereo or mono summing for single- or dual-subwoofer deployment. These controls help make the subwoofer easier to adapt to different speaker setups and room needs, while variable level control adds another layer of practical adjustment during configuration and use.
• XLR Inputs And Outputs Support Versatile System Routing: Flexible connectivity helps the Thump118S fit into a wide range of live sound systems with two XLR inputs, two high-pass XLR outputs, and two full-range XLR outputs. This layout supports practical routing options for integrating the subwoofer with full-range speakers and broader PA configurations, making it easier to build or expand a system around the demands of the event.
• Portable Design With Pole Mount And Easy Carry Handles: Built for gigging professionals, the Thump118S combines a portable enclosure with practical features that simplify transport and deployment. Two cut-through side handles make lifting and carrying easier, while the integrated M20-threaded pole mount lets you raise full-range speakers above the audience for proper system placement. A defeatable front LED adds one more useful setup option.
