So my theater is 11 x 14. Two rows of seats with the back less than 2 feet from the back wall. The ceiling is sloped up from 9 feet to 14 feet diagonal to the 14 feet longest wall. I've got a 5 channel system with one subwoofer. I'm using 4" mineral wool. Trying to get and idea of how much I should order and where I should place it.
Thanks in advance for the help.
