Hello All, I thought as this was my first ever post I would like to have a little fun. Last night I solved a huge problem with my setup that has been bugging me for months. First a quick history lesson: In Dec last year my girlfriend and I decided that this year we were gonna spend our surplus cash on fun things for the house and one of those was a new hi-fi to replace my 10 year old separates system. We agreed a home theater would be a very good thing to have, yes thank god, she is one of those girlfriends who is just as electronics mad as we are!!!!. So we after buying the other things on the list it ws time to go find what we wanted. We bought the system in June this year and all was well. The systems sounded fantastic. Better than I ever could have imagined. August 2001 - 18 October 2001: So there I was innocently listening to some music when suddenly my attention was attracted by the sub. I could hear every bass note perfectly, but whereas before it was integrated perfectly with the other speakers this time I could tell extactly where the sub was, in the corner. I tried with various postions and setup an no matter what I could locate the sub every time, even blindfolded!!!!!! Add to that as every day went by the system sounded odder and odder, more unbalanced, one day the left front channel would sound overpowering, the next it was the right front, then the center.....it goes on. This was driving me mad, and my GF too because I was constantly changing the speaker postions and levels, and many arguments ensued, I even bought a calibration disc to calibrate 100% but to no avail the system still sounded 'odd' but I just couldn't put my finger on what was wrong. Last Night (18 October 2001): Having recently bought SWTM was messing about with the features when the anwser dawned on me. 5 minutes later everything was back to how it should be. Sigh. My questions to you, my fellow HT nuts, Is what do you think was wrong with my system and how did I solve it?
