It is intended for DJs, performers, venues, and event setups that need more bass extension than full-range speakers alone can provide. Its built-in amplifier eliminates the need to match and carry a separate external subwoofer amplifier.\u003c\/p\u003e\u003cp\u003eWith a 1400-watt peak Class-D amplifier and a 15-inch ferrite woofer, the THUMP115S is built for amplified music playback and live-performance reinforcement. Mackie specifies a maximum peak sound pressure level of 131 dB. The subwoofer's published frequency response extends down to 36 Hz, helping it reproduce kick drums, bass instruments, and electronic music fundamentals.\u003c\/p\u003e\u003cp\u003eSelectable high-pass modes let the THUMP115S adapt its response to the rest of the PA system. Flat provides a balanced default response, while Deep emphasizes lower bass extension and Punch prioritizes higher output. A Variable mode provides adjustable crossover selection from 80 Hz to 160 Hz for matching a wider range of top speakers.\u003c\/p\u003e\u003cp\u003eStereo balanced XLR inputs support connection from a mixer or other line-level source. Stereo high-pass XLR outputs can feed powered top speakers while routing low frequencies to the subwoofer, and stereo full-range outputs can pass signals to additional equipment. A stereo\/mono full-range output option also supports practical multi-subwoofer deployment.\u003c\/p\u003e\u003cp\u003eThe THUMP115S is a professional PA subwoofer rather than a conventional 12-volt car-audio subwoofer. It uses AC mains power and balanced XLR audio connections, making it appropriate for portable PA, DJ, stage, and installed sound applications with compatible line-level equipment. Its integrated M20 threaded pole mount can support a compatible speaker pole for positioning top speakers above the subwoofer.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e15-Inch Ferrite Woofer:\u003c\/strong\u003e Produces dedicated low-frequency output for PA systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1400W Peak Class-D Amplifier:\u003c\/strong\u003e Provides built-in powered operation without an external amp.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFour High-Pass Modes:\u003c\/strong\u003e Flat, Deep, Punch, and Variable options tailor system behavior.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable 80–160 Hz Crossover:\u003c\/strong\u003e Helps match the subwoofer with compatible top speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStereo XLR Connectivity:\u003c\/strong\u003e Supports balanced inputs plus high-pass and full-range outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection Circuitry:\u003c\/strong\u003e Limiting and thermal safeguards help protect the amplifier and driver.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe THUMP115S uses a compact powered-subwoofer format with integrated top-corner carrying handles and a 15-inch ferrite low-frequency driver. Its Class-D amplifier uses convection cooling, and the front power LED can be switched off when a less visible stage appearance is preferred. The cabinet includes an integrated M20-threaded pole mount for a compatible loudspeaker pole.\u003c\/p\u003e\u003cp\u003ePlace the subwoofer on a stable floor or stage surface; it is not designed for suspension or for mounting the subwoofer itself on a pole. Connect balanced line-level signals from a mixer to the XLR inputs, then use the high-pass outputs to feed compatible powered top speakers when desired. Use the Variable crossover setting from 80 Hz to 160 Hz when matching the system manually, and leave clearance behind the cabinet for ventilation.\u003c\/p\u003e","brand":"Mackie","offers":[{"title":"Default Title","offer_id":45669410340934,"sku":"THUMP115S","price":749.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61gumZXSVWL.jpg?v=1784499482","url":"https:\/\/audiowatt.store\/products\/mackie-thump115s-15-1400w-powered-subwoofer","provider":"Audio Watt Store","version":"1.0","type":"link"}
