Correcting Phase of STA311b System with speaker response?

I built a system using a ad converter (PCM4202 from TI) and a sta311b DSP. I drive the power fets with the ffx pwm stage of the sta311b.

When I measure the phase response of the hole system (without any dsp settings) I get a very bad phase plot.

Is it possible to correct the phase with the speaker tune option? Can I measure the Phase and generate a speaker response file like I would do with a mems microphone?

Thanks in advance.
