Jay is referring to sound reflections, Albert, esp off your nice hardwood floor there. Consider putting an area rug(I did this myself) in between your viewing area and your TV/front speakers, ie under your coffee table there, this will help stop reflected sound off of the floor which can 'muddy' the sound. This is because the reflected sound hits you slightly after the initial sound from your speakers.

Half of communication is listening. You can't listen with your mouth.
