It features a direct-radiating design with dual B\u0026amp;C 18\" drivers, each equipped with oversized 4\" voice coils to handle high power and deliver ultra-low frequency extension. Its bass-reflex cabinet pushes substantial acoustic energy down to 30Hz with clarity and punch.\u003c\/p\u003e\r\n\r\n\u003cp\u003eEquipped with a 4000W RMS Class D amplifier and onboard DSP, the MUSE 218 SA delivers a peak SPL of up to 148.5dB. Its DSP presets include cardioid settings, enabling systems with reversed subwoofers in an array to reduce rearward bass energy by more than 15dB—perfect for stages, arenas, or outdoor festivals where controlling bass spill is essential.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe enclosure is precision-engineered using 18mm birch plywood and optimized through BEM-type acoustic simulations to reduce duct resonance and turbulence. Its durable finish withstands the rigors of touring, while six integrated handles allow for safe and efficient handling. The reinforced steel grille with internal fabric offers added transducer protection, and the rear panel is pre-configured to accept optional swivel-mount caster wheels for added mobility.\u003c\/p\u003e\r\n\r\n\u003ch3\u003eMUSE 218 SA Features\u003c\/h3\u003e\r\n\u003cul\u003e\r\n  \u003cli\u003eDirect-radiating active subwoofer for ground-stacked setups\u003c\/li\u003e\r\n  \u003cli\u003e2 × 18\" B\u0026amp;C woofers (460mm) with 4\" (100mm) voice coils\u003c\/li\u003e\r\n  \u003cli\u003e4000W RMS Class D amplifier (8000W peak)\u003c\/li\u003e\r\n  \u003cli\u003eAdvanced DSP with cardioid presets for directional bass control\u003c\/li\u003e\r\n  \u003cli\u003ePeak SPL output of 148.5dB\u003c\/li\u003e\r\n  \u003cli\u003eExtended low-frequency performance down to 30Hz (-6dB)\u003c\/li\u003e\r\n  \u003cli\u003eCardioid mode reduces SPL at rear by over 15dB\u003c\/li\u003e\r\n  \u003cli\u003eBass-reflex cabinet optimized using BEM simulations\u003c\/li\u003e\r\n  \u003cli\u003e18mm birch plywood construction with scratch-resistant finish\u003c\/li\u003e\r\n  \u003cli\u003eReinforced front grille with internal protective fabric\u003c\/li\u003e\r\n  \u003cli\u003eSix integrated side handles for ease of transport\u003c\/li\u003e\r\n  \u003cli\u003eRear panel pre-fitted for 4 × optional 100mm (4\") swivel casters\u003c\/li\u003e\r\n  \u003cli\u003eM20 threaded socket on top for speaker poles\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch3\u003eMUSE 218 SA Specifications\u003c\/h3\u003e\r\n\u003cul\u003e\r\n  \u003cli\u003eConfiguration: Direct-radiating, bass-reflex subwoofer\u003c\/li\u003e\r\n  \u003cli\u003eTransducers: 2 × 18\" B\u0026amp;C woofers (460mm) with 4\" voice coils\u003c\/li\u003e\r\n  \u003cli\u003eAmplifier: Class D – 4000W RMS \/ 8000W peak\u003c\/li\u003e\r\n  \u003cli\u003eFrequency Response: 30Hz – 100Hz (-6dB)\u003c\/li\u003e\r\n  \u003cli\u003eMax SPL: 148.5dB peak \/ 142.5dB continuous (half-space)\u003c\/li\u003e\r\n  \u003cli\u003eDSP Control: Presets including cardioid configuration\u003c\/li\u003e\r\n  \u003cli\u003eInput\/Output: XLR in \u0026amp; link out\u003c\/li\u003e\r\n  \u003cli\u003eInput Impedance: 22 kOhms\u003c\/li\u003e\r\n  \u003cli\u003eEnclosure: 18mm birch plywood with black scratch-resistant coating\u003c\/li\u003e\r\n  \u003cli\u003eGrille: Steel with internal protective cloth\u003c\/li\u003e\r\n  \u003cli\u003eHandles: 6 total\u003c\/li\u003e\r\n  \u003cli\u003eCaster Mounting: Rear panel supports 4 × 100mm (4\") swivel casters (optional)\u003c\/li\u003e\r\n  \u003cli\u003eTop Mount: M20 pole socket\u003c\/li\u003e\r\n  \u003cli\u003ePower Cable Length: 16.4 ft (5 m)\u003c\/li\u003e\r\n  \u003cli\u003eProduct Dimensions (W × H × D): 44.88 × 28.13 × 21.85 in (1140 × 714 × 555 mm)\u003c\/li\u003e\r\n  \u003cli\u003eNet Weight: 218.3 lb (99 kg)\u003c\/li\u003e\r\n  \u003cli\u003eShipping Dimensions (W × H × D): 47.24 × 31.49 × 28.74 in (1200 × 800 × 730 mm)\u003c\/li\u003e\r\n  \u003cli\u003eShipping Weight (with pallet): 238 lb (108 kg)\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch3\u003eWhat's In The Box\u003c\/h3\u003e\r\n\u003cul\u003e\r\n  \u003cli\u003eFBT MUSE 218 SA Powered Subwoofer\u003c\/li\u003e\r\n  \u003cli\u003ePower Cable\u003c\/li\u003e\r\n  \u003cli\u003eUser Manual \/ Technical Sheet\u003c\/li\u003e\r\n\u003c\/ul\u003e","brand":"FBT","offers":[{"title":"Default Title","offer_id":51135403786522,"sku":"116205","price":8099.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0894\/2714\/9082\/files\/ableton-muse-218-sa_413c9bf1-2b73-4168-ba99-53caa7dc10cf.webp?v=1759181067","url":"https:\/\/squarecable.com\/products\/ableton-muse-218-sa","provider":"SquareCable","version":"1.0","type":"link"}
