The FBT X-Sub118SA

The SUBline 118SA has been completely redesigned with a bass-reflex configuration, 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 amplifiersswitch 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. The Neutrik TRUE1 Power connection negates the need for a power switch while offering a solid locking connection.

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