Not being familiar with the Emotiva equipment I couldn't hazard to guess why the sub is not outputting for the test tones, it should be. You should try and give them a call to see what's going on.

Most people, from what I have read and from my own experience, set the Hsu subs gain in the 9 to 10 o'clock position and fine tune it from there. I'm glad you are enjoying the sub, it is a nice one.
