{"product_id":"fbt-subline-112sa-active-subwoofer","title":"FBT Subline 112SA Active Subwoofer","description":"\u003cp data-start=\"802\" data-end=\"1381\"\u003eThe FBT Subline 112SA is a compact professional active subwoofer designed to add powerful low-frequency performance to portable and installed sound systems. Built around a 12\" high-excursion woofer with a 3\" voice coil and powered by a 700W RMS Class D amplifier, it provides strong bass output from a cabinet that remains manageable for transport, setup and integration into smaller AV systems. FBT describes the Subline 112SA as a compact active subwoofer for applications where powerful bass is required in a portable, lightweight format. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"1383\" data-end=\"1840\"\u003eThis subwoofer is well suited to mobile DJs, live sound users, AV installers, schools, houses of worship, hospitality venues, bars, small stages, rehearsal spaces, event production teams and hire companies that need a compact low-frequency extension solution. It can be used with FBT active full-range loudspeakers, including compact point source cabinets such as the Ventis range, to create a more complete sound system with improved bass depth and impact.\u003c\/p\u003e\n\u003cp data-start=\"1842\" data-end=\"2314\"\u003eThe Subline 112SA uses a 1 way bass reflex configuration, helping deliver efficient low-frequency output from a compact enclosure. Its frequency response is listed as 40Hz to 140Hz at -6dB, making it suitable for reinforcing kick drum, bass guitar, electronic music, playback systems and general programme audio. With a maximum SPL of 130dB continuous and 133dB peak half-space, it offers impressive output for a 12\" active subwoofer. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"2316\" data-end=\"2843\"\u003eThe integrated 700W RMS amplifier removes the need for a separate power amplifier, making the system easier to deploy and specify. For portable users, this reduces rack space and system complexity. For fixed installations, it simplifies system design by combining the amplifier and subwoofer into one matched package. Peak amplifier power is listed at 1400W, giving the Subline 112SA the headroom required for dynamic low-frequency performance in real-world AV and live sound applications. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"2845\" data-end=\"3372\"\u003eIntegrated DSP provides useful system tuning flexibility. FBT lists 8 DSP presets, allowing the subwoofer to be adapted to different speaker combinations and applications. This is particularly useful when pairing the Subline 112SA with active full-range cabinets, as the correct preset can help improve system balance, crossover behaviour and overall sound quality. For installers and sound engineers, this makes the subwoofer more practical across different room types and system layouts. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"3374\" data-end=\"3869\"\u003eThe Subline 112SA includes balanced stereo XLR inputs and link outputs, allowing it to sit neatly within a professional audio signal chain. This makes it suitable for use with mixers, DSP processors, audio interfaces and active loudspeaker systems. Volume control, phase inversion and high-pass filter functions are also included, helping support cleaner integration with top speakers and allowing the system to be adjusted to suit the venue or application. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"3871\" data-end=\"4354\"\u003eThe cabinet is constructed from Baltic birch plywood with a scratch-resistant paint finish, giving it the durability required for professional use. This makes it suitable for portable systems that are regularly moved between venues, as well as fixed installations where cabinet strength and long-term reliability are important. Ergonomic carrying handles are included, making the subwoofer easier to lift and position during setup and pack-down. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"4356\" data-end=\"4755\"\u003eAn M20 top mount is provided for pole mounting a full-range loudspeaker above the subwoofer. This is useful for compact PA systems, DJ setups, school events, function rooms and smaller live sound systems where a neat sub-and-top arrangement is required. With the correct pole and compatible speaker, the Subline 112SA can form the low-frequency foundation of a compact but professional sound system.\u003c\/p\u003e\n\u003cp data-start=\"4757\" data-end=\"5156\"\u003eThe Subline 112SA measures 430 x 447 x 480mm and weighs 22.8kg, making it compact enough for mobile use while still offering meaningful low-frequency output. Transport dimensions are listed as 582 x 545 x 530mm, with a transport weight of 26kg. These figures are useful for hire companies, installers and venues planning transport, storage and system logistics. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp data-start=\"5158\" data-end=\"5618\"\u003eFor customers looking to add low-frequency extension to an active loudspeaker system, the FBT Subline 112SA provides a strong balance of power, portability and installation practicality. With a 12\" driver, 700W RMS Class D amplifier, 133dB peak SPL, DSP presets, XLR input and link outputs, phase control, high-pass filtering, birch plywood construction and M20 pole mount, it is a capable compact subwoofer for both portable and installed sound reinforcement.\u003c\/p\u003e","brand":"FBT Audio UK","offers":[{"title":"Black","offer_id":56657043456386,"sku":"41223","price":810.0,"currency_code":"GBP","in_stock":true},{"title":"White","offer_id":56657043489154,"sku":"41223W","price":810.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/5767\/2578\/files\/Subline112SA_06fcc8cb-c180-461c-a9c0-1cbe09920208.png?v=1779116475","url":"https:\/\/www.theavbarn.co.uk\/products\/fbt-subline-112sa-active-subwoofer","provider":"The AV Barn","version":"1.0","type":"link"}
