I didn't think the DSP chip was meant to 'flatten' bass response, I thought the whole idea was to keep the amp from distorting... or is that the same thing?
I always thought it was more of a safety feature from damaging the speaker than it was a tool to help its actual musical performance.
I think it accomplishes both. From the EP800 product page:
The Intelligent DSP wants things to go smoothly all the time - no bumps in the road. Using a digital roadmap, the special algorithm controls every frequency from 13 Hz to 150 Hz, never deviating more than 1 dB through this entire range.
It sounds like it definitely works at keeping the output even at every frequency.
