@rwwear No the DD series has automatic room and main speaker EQ if you run the output into your preamp. But I never use the electronic xover in the sub for the main speakers. I want my mains to run full range without any other electronics to distort the signal.
You weren't alone and may have been the impetus for the now twelve year old Velodyne Plus software redesign. The Plus Auto EQ now produces an improved and stunningly unnoticeable integration during the approximately twenty minute optimization cycle without any adjustment of the main speakers.
