MUSE 218SND is a direct radiation ground subwoofer, has two B&C 460mm long excursion speakers with 100mm voice coil and 4000W class D amplification, capable of 148.5dB SPL. The bass-reflex cabinet offers substantial energy up to 30Hz and is ideal for extending and reinforcing the low frequencies of the MUSE 210LND line array in ground-stack configuration.

It has presets to create various configurations with cardioid directivity, where some subwoofers face rearwards from the audience to acoustically cancel the sound pressure behind the cluster, obtaining a reduction of the SPL on the back by over 15dB.
The enclosure, optimized with BEM-type acoustic simulations to reduce resonance and turbulence of the ducts, is built with 18mm birch plywood with six handles and scratch-resistant paint. Reinforced front mesh with protective fabric and provision for optional four swivel-mount 4 ‘’ (100mm) casters in the rear panel.

The summit of the entire project is the new 4000W amplification module with built-in TCP / IP network interface. Based on the OCA ALLIANCE AES70 standard, the new MUSE family receives 24-bit 48-96Khz digital audio streaming from all devices compatible with the DANTE standard and communicates with the INFINITO System Management Suite remote control software. The module is contained in an aluminium chassis with intelligent forced ventilation and is equipped with an OLED display with encoder for parameter setting and a high-brightness blue front LED allows remote identification of the device, also in daylight. Fully developed in house by the FBT R&D team, INFINITO is the revolution that enhances the user experience, reaching new heights in terms of performance and simplicity.
