I feel its great to see the frequency response realtime (to me very much worth the tag price) ... I have my frequency response relatively flat but still cant get the kick in the chest I want (i've moved the mic from where my head is supposed to be to my chest area and bumping up frequencies between 50-60hz. still no kick.
moreover, I have discovered that I have a peak at around 100hz that I can't touch
overall, its a great sub, it has eliminated any need to use multiple subs, because it can do it all by itself. But like all audio purchases, after purchasing, I have yet to really play with it - I'm spending more time looking at future upgrades. this habit of mine really sucks. I'm actually waiting for some room treatment before playing with it, I'm postponing watching some movies because I want to watch them after treatments and equalizing again.
