I went a year with using audyssey w/out turning off limiters on rythmik subs when doing room corrections....limiters off when running audyssey then after turn limiters on....having limiters on when measuring wasnt optimum. so many little things can throw off the best result. my front L/R positions werent optimum either, inch here/there...it all matters. need to be ocd.
