I recently moved and had to re-set up my home theater system and speakers. My speakers sound terrible now because they don't have a crisp sound to them and are "fuzzy" sounding at times especially on songs with more bass. I went and bought new speaker wire, shortened the length of the wires, made sure the connections were tight, decreased the "gain" on the receiver but it still doesn't sound great. I am frustrated with it now. Any suggestions?:confused:

One thing to be absolutely certain of would be the phasing of all the speakers. Be aware that if all the wires are not 'positive to positive' / 'negative to negative' then you'll lose bass response. It has to do with sound waves canceling frequencies, etc. - what you want is to get your system up and running again, so I'll forget the acoustics theory. Any chance you 'blew' the speakers out? Even a slight tear in a cone or a fried spot on the magnetic windings will cause the type of distortion you've described.
Hope this helps!
