Thanks for the suggestions. I'm definitely going to look into room treatments when I get some time and feel rested for this long 2 year basement remodel. I can procrastinate with the best of em!

New subs, AVR and amps are definitely on the want list but it might be a couple years before I get all of em. Spent so much money on the basement, new TV, new speakers etc. I really wanted to get new subs first but now I'm not sure. Even just a 2 channel amp for the M80's would be very nice to have.
