The FatCab is equipped with the BG12-F, a custom-made 12" loudspeaker with 60 watts of power handling, which was specially developed for use in the FatCab. The BG12-F sounds balanced even at low volumes, but it shows its true strengths at stage volume.

The 42 ounce magnet provides a tight and controlled low end. The loudspeaker supports the FatCab in its capacity to be a very rocking box. The BG12-C combines - with a higher resilience - the creaminess of the Celestion Greenback with the low-end of the Celestion Vintage 30.
