FBT Subline Introduction


The Subline 115SA is equipped with a brand new Class D 700w amplifier that allows the subwoofer to reach an enormous sound pressure level of 135dB. This sub is also fitted with a powerful digital signal processor that features eight equalizations presets with low-pass filter crossover and a cardioid configuration. On the rear of the 115SA is a control panel with controls for volume, EQ presets, phase reversal as well as an eight-step delay that ranges from 0.25m to 3.5m.

This subwoofer features two integrated aluminum handles, and an M20 top mounted speaker stand socket so you can mount a satellite speaker if necessary. It comes housed in a 15mm thick birch plywood enclosure that is covered with a scratch-resistant coating that keeps itself protected during transit.
