Holy sound waves, Batman! This certainly explains what one can do with an engineering degree or two. Now if we could only rearrange all our furniture. This is really, really in-depth stuff however our initial speaker layout will not match any of the placement pictures.
Our HT/Music room measures 12.5’ x 22.5’ with the listening/viewing done across the center of the short dimension, so we’re relatively close to everything. The two 8” subs will end up about 8’ apart with stand mounted speakers about 5.5’ apart just inside the two subs with the TV centered. Either sub will be about 6’ in from the nearest corner location
Like most audio decisions for the home, we’re doing this THINKING that it will improve/balance the sound. We’ll only KNOW after trying it. Your pictures suggest great alternative locations for two subs, especially configuration #3, but that it would prove impractical the way our room is laid out. If our idea doesn’t work out we’ll just go back to a single sub which is pretty ok as it is.
Thank you, arnyk.
