Which disc did you use to calibrate your HSU sub? I used the test disc provided by HSU but still feel that I didn’t calibrate the unit properly as I feel it’s not tuned properly for HT.

Has anyone used AVIA or any other test disc for tuning the sub? Also can someone elaborate on the phase switch of the sub – My sub plays louder at 180 degrees and quieter but smoother at 0 degree. I have currently set it up at 0 degree, should I try to calibrate at 180 as it is more bass heavy.

Any direction would be much appreciated.
