Built around a 1400W Class-D amplifier and a 15\" high-performance woofer that reaches a remarkable 27Hz low frequency — well into sub-bass territory that is felt as much as heard — the Thump 15S V4 delivers a maximum SPL of 132dB for the kind of powerful, chest-thumping bass that gets people on the dance floor and keeps them there. Whether deployed for DJ sets, live bands, karaoke or general PA applications, the Thump 15S V4 brings complex basslines, punchy kicks and deep low-end presence that no full-range loudspeaker alone can replicate.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eSelectable High Pass Modes for Perfect System Integration\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eA key feature of the Thump 15S V4 that sets it apart from simpler subwoofers is its four selectable high-pass modes, each pre-configured with the optimal crossover frequency for a specific Thump V4 loudspeaker pairing. Thump 12 mode sets a 140Hz crossover for Thump 12 V4 loudspeakers, Thump 15 mode sets a 110Hz crossover for Thump 15 V4 loudspeakers, and Thump GO mode sets a 150Hz crossover for Thump GO loudspeakers — removing all the guesswork from subwoofer and loudspeaker integration within the Thump V4 ecosystem. All modes include a 1.4ms alignment delay for phase-coherent system integration between the subwoofer and loudspeakers, ensuring a seamless, well-integrated combined response. A Variable mode allows the crossover frequency to be set manually for use with any third-party loudspeaker, making the Thump 15S V4 a versatile sub for mixed or non-Thump systems too.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eVersatile I\/O \u0026amp; System Configuration\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Thump 15S V4 provides a comprehensive range of input, output and configuration options for flexible system design. Stereo XLR inputs accept signals from DJ controllers, mixers and other source equipment, whilst stereo high-pass XLR outputs feed connected loudspeakers with the correctly filtered signal for seamless top and sub integration. Stereo full-range XLR outputs pass the complete unaltered signal to a second subwoofer for expanded low-end coverage in larger systems. Phase invert, stereo or mono summing for single or dual subwoofer deployment, and a variable level control from muted to +6dB allow precise output balancing and system optimisation. A defeatable front LED provides clean stage presentation when required.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003e\u003cstrong\u003eBuilt-Like-A-Tank™ with Smart Mounting\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThe Thump 15S V4's Built-Like-A-Tank™ construction ensures touring-grade reliability and durability for regular gigging, whilst the lightweight design and built-in handles keep it manageable for a single operator at 26kg. An M20 threaded top accommodates the Mackie SPM400 speaker pole (sold separately), allowing a Thump V4 loudspeaker to be pole-mounted directly above the subwoofer for a clean, compact and space-efficient self-contained PA stack — ideal for smaller venues, mobile DJs and gigging musicians who want a professional system without the complexity.\u003c\/p\u003e\n\u003ch3 class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eMackie Thump 15S V4 Key Features:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e1400W Class-D Amplifier:\u003c\/strong\u003e Delivers 132dB maximum SPL and 27Hz low-frequency response for deep, powerful and authoritative bass performance.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003e15\" High-Performance Woofer:\u003c\/strong\u003e Reaches floor-shaking 27Hz sub-bass for complex basslines and punchy kicks that are felt as much as heard.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eFour Selectable High-Pass Modes:\u003c\/strong\u003e Thump 12 (140Hz), Thump 15 (110Hz), Thump GO (150Hz) and Variable — each optimised for seamless loudspeaker integration with 1.4ms alignment delay.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eStereo XLR Inputs:\u003c\/strong\u003e Flexible connectivity from DJ controllers, mixers and other source equipment.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eStereo High-Pass XLR Outputs:\u003c\/strong\u003e Feed connected loudspeakers with the correctly filtered signal for seamless sub and top integration.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eStereo Full-Range XLR Outputs:\u003c\/strong\u003e Pass the complete unaltered signal to a second subwoofer for expanded low-end coverage.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eStereo \u0026amp; Mono Summing:\u003c\/strong\u003e Supports both single and dual subwoofer deployment configurations.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eVariable Level Control:\u003c\/strong\u003e Muted to +6dB output level adjustment for precise system balancing.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003ePhase Invert:\u003c\/strong\u003e Flexible phase alignment for different deployment configurations.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eM20 Speaker Pole Thread:\u003c\/strong\u003e Accommodates the Mackie SPM400 speaker pole (sold separately) for mounting a Thump V4 loudspeaker directly on top.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eDefeatable Front LED:\u003c\/strong\u003e Clean stage presentation when front-facing LED illumination is not required.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eBuilt-Like-A-Tank™ Construction:\u003c\/strong\u003e Touring-grade durability with built-in handles for easy single-operator transport.\u003c\/li\u003e\n\u003cli class=\"whitespace-normal break-words pl-2\"\u003e\n\u003cstrong\u003eLightweight at 26kg:\u003c\/strong\u003e Manageable for a single operator despite its powerful 15\" driver configuration.\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Mackie","offers":[{"title":"Default Title","offer_id":57112451875189,"sku":"THUMP15SV4","price":719.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2083\/7259\/files\/preview_33_775631d9-691c-4830-be26-9a58f018daf2.webp?v=1777460015","url":"https:\/\/www.audiovolt.co.uk\/products\/mackie-thump-15s-v4-active-pa-subwoofer","provider":"Audio Volt ","version":"1.0","type":"link"}
