Product Description

FBT engineers have installed the FBT Subline 118SA with a digital signal processor that has 6 in-built presets, allowing it to match the presets of other FBT PA speakers and subwoofers. This allows all the FBT fixtures to be on the same preset and will enable them to sound fantastic together!

The SUBline series has been completely redesigned and consists of 112SA, 115SA, 118SA, 218SA active and 118S and 218S passive subwoofer models, all bass-reflex , built in birch plywood and aimed to extend the low frequency response to a wide range of FBT speaker systems.

Created with the aim to maximize SPL/SIZE ratio, they have Class D amplifiers, switch mode power supply and Digital Signal Processor with presets to match any other FBT speaker.

With IN/OUT stereo connectors, it is possible to use only one subwoofer with Left and Right speakers

Optional wheels, ergonomic integrated carrying handles and tour-grade plywood cabinets allow an easy transport.
