I'm a little confused, I'm pretty sure Jakeman told me the reason my original 600 amp graphs looked the way they did is because of the brick wall filter inherent in the original DSP subs when they were released. My results in the new amp I received showed this filter was no longer in place. That was within the last 6 months.
Also, a few of us piloted a flash update using the computer interface, but this proved to not work in the field. New subs shipping from Axiom no longer incorporate the brick wall, as far as I understand with my conversations with Amie, and company.
