MUSE 218S is a direct radiation ground subwoofer, has two B&C 460mm long excursion speakers with 100mm voice coil and 4000W/4Ohm recommended amplifier power, capable of 148.5dB SPL. The bass-reflex cabinet offers substantial energy down to 30Hz and is ideal for extending and reinforcing the low frequencies of the MUSE 210 line array in ground-stack configuration.With external DSP presets is possible 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, optimised 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 rear facing input panel provides 2 Neutrik NL4 M Speakon female connectors.
