The length of Orion's DSP filters is insufficient for bandwidths below ~300 Hz, and ruins performance below ~180 Hz. There are probably also some computation inaccuracies. The 100 Hz DSP filter is a joke. It's ripples settle below -60 dB at 680 Hz bandwidth, and still hold above -75 dB at 1200 Hz bandwidth.
