So Ive got a BIC F12 with polk monitor 60s as my L/R, and a pok CS1 for my center. all other satellite speakers are from my previous Onkyo HTIB (HT-R667). I decided to put my old sub behind my sectional sofa. The room is 27X16ft. I ran audyssey while only having the BIC 12 plugged in and it set my sub at -11db and my L/R speakers set to large. Does this seem right. Doesnt seem like very much base. BTW crossover is set to 100Hz on onkyo and all the way up on the sub.
