Well im new to world of suround sound so for my first set up i purchased a HTIB (onkyo 502) i know its not the best but for my first step its fine for now. My question is my sub seem to provide very boomy base if it can be described that way. My room is a rectangle and the sub is in the corner of the room. Could i fix this by moving the sub, or is it my sub itself that is the problem? Thanks for the help.
