There is Digital Signal Processing in the F1 Model 812. It automatically optimizes the equalization to suit the position of the Flexible array (Straight, J, Reverse-J, C) and responds to the EQ switch so you can use the F1 Model 812 with the F1 Subwoofer.  There's no mention of the DSP in those terms because this all happens automatically. The DSP is not user accessible except by changing the position of the flexible array and the EQ switch.

It automatically optimizes the equalization to suit the position of the Flexible array (Straight, J, Reverse-J, C) and responds to the EQ switch (FULL RANGE/WITH SUB) so you can use the F1 Model 812 with the F1 Subwoofer.  There's no mention of the DSP in those terms because this all happens automatically. The DSP is not user accessible except by changing the position of the flexible array and the EQ switch.


==== Why Does the F1 Model 812 Passive Require Digital Signal Processing ====
==== Why Does the F1 Model 812 Passive Require Digital Signal Processing ====
The F1 Model 812 Passive requires active equalization because the F1 Model 812 Passive does not have a amplifiers or digital signal processing. Looking at the documentation for the [https://assets.bose.com/content/dam/Bose_DAM/Web/pro/global/products/portable_PA/F1_Model_812_Passive_Flexible_Array_Loudspeaker/downloads/AM740742_02_printable.pdf Bose F1 Model 812 Passive Loudspeaker Installation and Safety Guidelines] you will find a section about the active equalization that must be provided for the F1 Model 812 Passive to provide infrasonic bandpass protection, amplifier power limiting and active equalization.
