dBLimit Posted January 23, 2006 Share Posted January 23, 2006 I am having a problem with all the speakers in my house. Specifically, all of the front left channel speakers are behaving like they are wired out of phase. However, they are all connected properly (red to red, black to black). I believe I am receiving interference from a system (that is incorrectly wired) that is not in my house, but located close to where I live. Is this possible? Is there a way to fix something like this? Or am I out of luck? Anybody on this board live in the Ypsilanti/Ann Arbor, Michigan area? Maybe you're being affected too and you can help me out.

ironwoods Posted January 23, 2006 Share Posted January 23, 2006 Hi, Is this a whole house system, or seperate systems throughout? What indications are leading you to this assumption? Have you tried purposely wiring out of phase on the suspect channel(s)?. How many front-left speakers does one have? 1/2 of these questions could be answered by entering in your system(s) profile.

efzauner Posted January 23, 2006 Share Posted January 23, 2006 What do you mean by "out of phase" . You have to say "out of phase" with respect to something... How do you know it is not the the other channel that is out of phase. What do you hear? Did you try to connect some speakers directly to the amp and listen if you hear the same problem? Try to isolate what you think is the culprit and replace it and see if you where right... Quote Link to comment Share on other sites More sharing options...

dBLimit Posted January 23, 2006 Author Share Posted January 23, 2006 It was affecting separate systems throughout the house. All the systems in the house are correctly wired. I wired them myself and I am very particular about wiring. The systems have been acting fine for a year straight. All of a sudden last week I started having this problem. Very Strange. I double-checked all the systems to make sure. To see if I was right, I isolated the sound from my left channel computer speaker, then the right and compared both. The left channel was not producing bass correctly. It was "pulling" and the right channel was "pushing". But the computer speakers were wired correctly. Anyway, when I woke up this morning I played music and it seems the problem was corrected. Everything sounded in phase. I still don't understand why I was affected by it. Why should someone else's error affect me when I'm not even in the same building? Quote Link to comment Share on other sites More sharing options...
efzauner Posted January 23, 2006 Share Posted January 23, 2006 So, all is ok now! Great. I still am currious why you think the left channel was out. How do you know when a speaker should push and when it should pull when you are listening to music. You can check polarity by connecting a 9 volt battery to the speakers, or your house wiring without the amp connected. When the positive of the battery is connected to the positive speaker terminal, the cone should go out. Dont worry you cannot blow a speaker this way. You are not giving the speaker more than a watt, if that much. Quote Link to comment Share on other sites More sharing options...
dBLimit Posted January 24, 2006 Author Share Posted January 24, 2006 I didn't think it was out of phase, it was behaving like it was out with any signal that was played through it. Dude, I know what out of phase sounds like. It was acting that way for a week. It was annoying because there was nothing I could do about it.

Listen again with the correct wiring. It's not difficult to notice the difference. When out of phase, you lose bass, midrange, and some high frequency. Bass and midrange are affected the most I think. Quote Link to comment Share on other sites More sharing options...
