Dual 18-Inch Powered PA Subwoofer

The FBT MUSE 218 SA is a high-output, dual 18-inch powered subwoofer engineered for large-scale sound reinforcement, concerts, touring productions, and ground-stacked line array systems. Featuring two custom B&C high-excursion woofers, a 4,000W Class D amplifier, and a maximum peak SPL of 148.5dB, this bass-reflex subwoofer delivers powerful low-frequency reproduction down to 30Hz. Integrated DSP processing and cardioid configuration presets provide flexible bass management for demanding live sound applications.

FBT MUSE 218 SA Competitive Differences

  • Dual 18-Inch B&C Woofers: Two custom high-excursion B&C drivers with 4-inch (100mm) voice coils deliver high-output bass reinforcement.
  • 4000W Class D Amplification: Integrated high-power amplifier with switch-mode power supply delivers substantial output for large venues and live events.
  • 148.5dB Maximum SPL: Produces up to 148.5dB peak SPL in half-space conditions, with 142.5dB continuous maximum SPL.
  • 30Hz Low-Frequency Extension: Large bass-reflex enclosure provides deep bass reproduction down to 30Hz at -6dB, depending on DSP preset.
  • Integrated DSP Processing: Selectable sound presets support different bass responses, delay adjustments, phase control, and cardioid subwoofer configurations.
  • Cardioid Array Capability: Supports subwoofer arrangements designed to reduce unwanted rearward low-frequency energy by more than 15dB in properly configured systems.
  • Touring-Grade Birch Plywood Cabinet: Constructed from 18mm birch plywood with scratch-resistant black paint, six integrated handles, and a reinforced metal grille.
  • MUSE Line Array Integration: Designed to provide low-frequency reinforcement for MUSE 210LA line array systems in ground-stacked configurations.

FBT MUSE 218 SA Description

The FBT MUSE 218 SA is a processed active subwoofer designed to deliver controlled, high-impact low-frequency performance for demanding professional sound systems. Its dual 18-inch B&C high-excursion woofers feature 4-inch voice coils and are housed in a large bass-reflex enclosure optimized for high acoustic output. The integrated 4,000W Class D amplifier provides substantial power, while the cabinet design helps minimize port turbulence and unwanted resonance during high-output operation.

Onboard DSP processing allows the subwoofer to adapt to different performance requirements and system configurations. Selectable presets include original, deep, punch, infra, and cardioid rear configurations, while dedicated controls provide level, delay, and phase adjustments. Properly arranged cardioid subwoofer arrays can reduce low-frequency output behind the system, helping manage bass coverage on large stages and in venues where rearward sound control is important.

Built for the demands of touring and permanent installations, the MUSE 218 SA features a rugged 18mm birch plywood enclosure with textured, scratch-resistant black paint. Six integrated handles facilitate positioning, while the heavy-duty front metal grille with protective fabric helps safeguard the drivers. An M20 threaded pole socket supports compatible speaker stands, and the cabinet accommodates an optional set of four 4-inch (100mm) swivel casters for transportation.

The MUSE 218 SA is an ideal low-frequency extension for FBT MUSE 210LA line array systems, particularly in ground-stacked configurations using compatible mounting hardware. Balanced XLR input and link connections simplify integration with professional audio systems, while PowerCon AC input and loop output connections support power distribution. Its high output, durable construction, and flexible processing make it suitable for concerts, festivals, live music venues, theaters, houses of worship, and large-scale sound reinforcement installations.
