I followed the instructions from the user manual from my Ascend Acoustics speakers.

It said to measure from the center between the two mains, out to the center of your listening position. Take that number which is 12.4" for me, and multiply it by 0.73 to find the optimum distance between the two mains. Well, currently my mains are 4 feet apart (I will have to rearrange the entire room if this is insane). The math says they need to be 9 feet apart. So I am guessing my HT system sounds like crap probably due to this? Opinions please!
