You are most likely right about that. The DSP code can change the frequency
response of the system, and my measurements show the low frequency response
is off quite a bit from the published specs. I compensate by turning up the
50 Hz EQ on the W2IHY 8-Band, and that seems to fix the problem, although
it's not truly flat audio response.
That's one of the things I have on my "List of things for Ten Tec to fix" on
my website!
