FBT MODUS 118FSA-Subwoofer
The FBT MODUS 118FSA is a single 18'' subwoofer with a bass-reflex design and compact dimensions that make it ideal for suspension. Designed to support one or two MODUS 4805LA or 4820LA modules and aesthetically similar to a 4805 module, the sub is capable of very high SPL in relation to its size. It can either be suspended above the line array modules or ground stacked. Additionally, the 118FSA can be used in conjunction with the 215FSA to further extend and reinforce low end performance.
