FBT Muse 218S – Powerful Passive Subwoofer for Professional Concert Applications

The FBT Muse 218S subwoofer represents the highest class of professional audio equipment, combining innovative engineering with the reliability essential for demanding touring and event conditions. This passive low-frequency system was designed to deliver massive low-frequency support that fundamentally impacts the experience of every concert or festival. Thanks to two powerful 18-inch low-frequency drivers with 4-inch voice coils manufactured by the renowned brand B&C, this subwoofer offers deep, extended bass with incredible dynamics and power. The device achieves an impressive peak sound pressure level of 148.5dB, making it the ideal solution for the most demanding concert, festival, and outdoor applications.

Product Features

The subwoofer stands out with the following key features: two 18-inch B&C drivers with high excursion and 4-inch voice coils ensuring maximum performance, a bass reflex construction guaranteeing optimal output efficiency and reduced distortion, a recommended power rating of 4000W RMS enabling operation at the highest volume levels, an impressive maximum SPL reaching 148.5dB, a cabinet made of 18mm birch plywood covered with a scratch-resistant coating, dual Speakon NL4M connectors for secure input and signal linking, the ability to configure a cardioid array allowing precise shaping of the directional pattern, and full compatibility with the MUSE 210L system for creating coherent line arrays.

Professional Performance for Major Events

The Muse 218S subwoofer was designed as the foundation of powerful sound reinforcement systems, offering deep and extended bass that adds impact and power to any full-range system. The ground-stacked construction allows for efficient placement of subwoofers on the stage floor, where their acoustic energy can be optimally utilized to enhance the low-frequency effect. With a cutoff frequency of 30Hz (dependent on preset settings), the device reproduces the deepest tones that are physically felt by the audience, creating an immersive audio experience. The maximum sound pressure level of 148.5dB in half-space configuration with bi-amping provides sufficient power reserve for the largest concert venues and festivals. The subwoofer requires external power amplifiers and system processors, such as the DLM series, allowing for full control over the sound characteristics and optimization for specific acoustic conditions.
