It adds dedicated bass reinforcement for music playback, DJ sets, small venues, presentations, and portable PA applications. Its integrated amplifier means it can be connected directly to a mixer, DJ controller, or other balanced line-level source without requiring a separate subwoofer amplifier.\u003c\/p\u003e\u003cp\u003eThis subwoofer is well suited to performers, mobile DJs, event providers, houses of worship, schools, and anyone building a compact powered PA system. The 15-inch woofer and Class-D amplification are designed to handle low-end material such as kick drums, bass guitar, electronic music, and recorded program audio. With a 132 dB peak maximum SPL rating, it is intended for applications where a full-range speaker system needs greater bass capability.\u003c\/p\u003e\u003cp\u003eThe Thump15Sv4 delivers a published frequency response of 27 Hz to 160 Hz at -10 dB, with a 34 Hz to 160 Hz response at -3 dB. Its onboard 1400-watt peak Class-D amplifier powers the low-frequency driver and uses convection cooling. Peak and RMS limiting, plus power-supply and amplifier thermal protection, help support dependable operation during demanding use.\u003c\/p\u003e\u003cp\u003eFlexible crossover processing helps the Thump15Sv4 integrate with compatible powered loudspeakers. Dedicated high-pass modes are provided for Mackie Thump12v4, Thump15v4, and Thump GO speakers, while Variable mode allows adjustment for other connected loudspeakers. Each preset high-pass mode includes 1.4 ms of alignment delay to assist with system integration.\u003c\/p\u003e\u003cp\u003eStereo balanced XLR inputs accept a source signal, while separate balanced XLR full-range and high-pass outputs support expansion to top speakers or additional subwoofers. A stereo\/mono full-range output mode, variable level control, and polarity invert switch provide useful setup control. The cabinet also includes an M20 threaded mount for an optional Mackie SPM400 speaker pole, allowing a compatible top speaker to be placed above the subwoofer.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e15-Inch Woofer:\u003c\/strong\u003e Dedicated low-frequency driver supports fuller bass in powered PA systems.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e1400W Peak Class-D Amplifier:\u003c\/strong\u003e Built-in amplification eliminates the need for a separate subwoofer amp.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e132 dB Peak SPL:\u003c\/strong\u003e Supports high-output use in portable live-sound applications.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable High-Pass Modes:\u003c\/strong\u003e Helps match the subwoofer to Thump speakers or other PA tops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced XLR I\/O:\u003c\/strong\u003e Connects easily with mixers, DJ controllers, speakers, and additional subs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM20 Pole Mount Thread:\u003c\/strong\u003e Accommodates an optional threaded pole for mounting a top speaker.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe Thump15Sv4 uses rugged modern construction with integrated ergonomic carry handles for transport.
