Speaker Placement and boundary problems

[midrange]

There is a lot to read here and probably a lot of detail but here is just an easy quick tip to always have perfect stereo sound to each ear.

The Distance you are from the TV/RECEIVER, that is the distance the speakers should be spread apart.in all corners.

The sub, bass freq. travels where ever it wants. That you just move around till you find whats best. I have always found the sub towards rear facing tv in corner or behind couch throuws the best bass sound that spreads the whole room. (also depends on the room)
