Ok, Today I came home and changed only my front speaker cables. I have powered towers in the front. These are connected thru the lfe on the receiver. So again all I did was change speaker wire. My problem is I have lost some of the volume of the bass. I had to increase the db's on the sub level on the reciever to get what I think I have lost. So, I went back to the old cables and it sounds the same again with low lfe levels. Is it possible that I am thinking it does when it does not. I did not listen to the reciever until after I came home from work and changed the cables. My wife thinks it sounded a little week also. Could the reciever the culprit? I have run test tones and the sub rattles the house. But when listening to music or movies it becomes very low. Any help would be great.
