His seats are in the middle of his room with a lot of "walking space" around them, but not a real good location for putting the sub closer. I know that it is 9.5 feet from the middle of his 2 rows of seats (we physically measured it the other night during calibration). Anything else would change that by maybe 2 feet tops.
I told him again that I will bring over my DIY sub when he is ready to invest into a sub. Then he can borrow the sub for a weekend and give a larger sub a trial run. I have all of my math calculations for ideal seating locations to avoid standing waves/room harmonics (granted those are for "rectangular" rooms though) to try to avoid the big nulls, and his seats were pretty close to on the mark that we left them.
He told me that his "sub" has an 8" woofer and is 125 watts, but it got distorted pretty easily. A 12" with around 300 watts will do much better. Not perfect, but I think that it will really impress him.
