FBT MUSE 218S — Passive 2×18″ Ground-Stack Subwoofer
MUSE 218S Overview
The FBT MUSE 218S is a passive 4000W ground-stacked subwoofer designed as the low-frequency foundation for the MUSE passive line array system, with primary compatibility alongside the MUSE 210L line array module. Built for concert touring, festivals, outdoor events, and large-scale fixed installations, the 218S delivers deep, extended bass reinforcement and a maximum SPL of 148.5dB. The cabinet houses two 18″ B&C high-excursion woofers with 4″ voice coils in a bass reflex enclosure, optimized for maximum output efficiency and reduced distortion. System integrators and touring engineers requiring scalable, high-output passive subwoofer solutions will find the 218S a purpose-built component within the broader MUSE ecosystem.
The MUSE 218S is designed for use with external amplifiers and system processors, including the FBT DLM series, and features rear-panel NL4 Speakon connectors for secure signal input and system linking.
Key Features
- Dual 18″ B&C High-Excursion Woofers — Two B&C drivers with 4″ voice coils provide the transducer foundation for high-output, low-distortion bass reinforcement at concert and festival scale
- 4000W Passive Design — Passive architecture allows amplifier selection and system configuration to be tailored to specific deployment requirements
- 148.5dB Maximum SPL — Delivers the headroom required for large outdoor events and high-SPL touring applications
- Bass Reflex Enclosure — Cabinet tuning maximizes low-frequency output efficiency and extends bass response for full-range system integration
- Extended Low-Frequency Response — Frequency response reaches down to 30Hz, with the upper limit preset-dependent based on system processor configuration
- NL4 Speakon Connectivity — Rear-panel NL4 Speakon connectors provide secure, roadworthy signal input and linking for multi-cabinet deployments
- MUSE System Integration — Engineered specifically for use with the MUSE passive line array series, particularly the MUSE 210L, ensuring matched system performance and processor compatibility
- DLM Series Processor Compatibility — Designed for use with FBT DLM series system processors for optimized crossover, limiting, and alignment control
Connectivity & I/O
