I changed the 5T's and 5C to 60, the sub at 80 and the surrounds at 100 and I put the sub volume at +2. What else do I need to adjust to be able to feel the bass. It sounds pretty darn good now but I know I still don't have something right. I am forever grateful I did not waste my $2,000 on a set of BOSE. My system as it is right now will blow the 2 grand bose system away but I know it has even more sound in it if I was an audio guru to get my sub set right. I wish I knew someone.
