FBT Muse 218 SA - 8000W 2 x 18-inch Powered Band Pass Subwoofer with 4-inch Voice Coil in Black Finish

The FBT Muse 218 SA is a high-performance powered band-pass subwoofer, engineered to deliver deep, powerful low-frequency output in both live sound and fixed installation applications. This subwoofer is designed to extend and reinforce the low frequencies of the Muse 210LND line array system when configured in a ground-stack setup, making it an ideal companion for large events, concerts, and other sound reinforcement applications requiring substantial sub-bass energy. Featuring dual 18-inch B&C woofers with 4-inch voice coils, the Muse 218 SA produces a powerful and controlled bass response, capable of reaching impressive SPL levels of up to 148.5dB peak. The subwoofer's frequency response extends down to 30Hz, ensuring deep, clear bass extension for a full-range audio experience.

At the core of the Muse 218 SA is a 4000W RMS Class D amplifier, which provides efficient power handling and excellent thermal management. The switch-mode power supply ensures high-performance output with minimal energy loss, while the 8000W peak power allows the subwoofer to reach maximum output levels without distortion. The amplifier is housed in a rugged die-cast aluminum structure, which not only protects the internal components from dust but also facilitates efficient heat dissipation, ensuring the system performs optimally during long, demanding events. The enclosure is designed using advanced BEM-type acoustic simulations to minimize resonance and duct turbulence, ensuring low distortion and high fidelity in low-frequency reproduction.

The Muse 218 SA is constructed with a durable 18mm birch plywood cabinet that features scratch-resistant black paint, ensuring the subwoofer remains in top condition even after extensive use in the field. The front of the cabinet is protected by a heavy-duty metal grille and synthetic protection cloth, safeguarding the drivers during transport and handling. For enhanced mobility, the Muse 218 SA includes six integrated handles and an option for four swivel-mount 4-inch casters, making it easier to move the subwoofer around during setups and breakdowns. Additionally, the subwoofer features an M20 top-mount stand socket for convenient pole mounting when needed.

For flexibility in sound coverage, the Muse 218 SA supports cardioid configurations, where certain subwoofers are oriented rearward to acoustically cancel sound pressure behind the cluster. This cardioid setup reduces SPL by over 15dB at the rear of the array, making it ideal for situations where control over low-frequency dispersion is critical. The Muse 218 SA is equipped with integrated rigging hardware, allowing for seamless integration with the Muse 210LND array system and ensuring easy and secure suspension of the subwoofer.
