All BASSBOSS MK3 loudspeakers include integrated comprehensive DSP with a 96kHz sampling rate and pushbutton onboard presets. There's no fixed number: each model has its own set, tuned for that cabinet. See the model's product page at bassboss.com or the Preset Guide at bassboss.com/learn/tools/presets for the current list.
All presets include high pass filters, low pass filters, phase alignment, equalization and multi-stage limiting. ControlBASS can store up to 100 presets.
