According to Polk, when I turn the balance to the right I should still be able to hear some music from the left speaker. I am getting nothing. I do get sound from the right when I turn the balance to the left. I have checked the phase of my hook up(at least four times) and it is good. I then switched the sda cable around to see if it was the problem, no change:mad: I then reversed the speakers, left to right, right to left, and the exact opposite happened, so basically the problem is following the left speaker:eek:Anyone have a solution:confused:

    I believe he has a NAD C372 integrated.

    Check inside for a loose connection. Check that the SDA drivers in the left channel move freely.

    I am using a Onkyo, have not received the NAD yet. Yes, all of the drivers seem to be moving in time with the right, and are putting out sound when balance is neutral. Do not see any loose connections. The SDA is a little loose, but I have switched this around and it does not seem to make any difference. :confused: I appreciate the help, hopefully we can get this figured out.

    Check for a loose or dirty connection inside and outside where the SDA cable plugs in.

    You may be best off removing the passive radiator and look through the front.

    also, looking at the wiring diagram in the polk user manual, it showes a picture of the amp as if you are looking at it from the front, and the right channel is actually on the left hand side, looking strait ahead. So, looking from the front of the speakers forward, the right channel is on your right side, and the left on your left. This is backwards from what the diagram shows on the back of the speakers, which shows the listener looking at the speakers, right channel being on the right, left on the left. Having said this, it sounds much better when I have it wired the way the manual shows, not the back of the speaker.:confused:Anything I need to know before taking the back plate off, or the passive bass radiator:confused:Thanks

    yep, this is what I would have thought, and is the way it states to set it up on the speakers themselves. When I set it up this way it does not sound very good. When I set it up the incorrect way, it sounds damn good. Any way this is related to the original problem that started this thread:confused:

    Most likely, or maybe the guy who put the stickers on was stoned?

    something is not right:eek:I can say this for sure, the SDA cable is not what I would call a tight fit. I do not know if it is the original. The set up I have going into the speakers is set up correctly. I have the laptop with a y adaptor running into the receiver, which then runs through a equalizer:confused:

    That's an aftermarket cable. Check the continuity of the blades and report back.

    yeah, the cable does not fit tightly into the speakers. Having said that, both ends do work on the right speaker, as far as the balance thing is concerned, as I have tried both ends to see if there may have been a short or something. Now, I have a feeling that all of this may be due to the same issue, just not sure what the cause is.(speakers sounding much better when reversed, balance issue):mad:I do not see any problems in the run of the cable as far as crimps or any tearing of the insulation:eek: I appreciate everyones help

    Like F1nut said there must be a loose connection in the XO. Pull the big metal plate off in the front.

    Again, I want you to check continuity. Test the large blade to the large blade and report back.

    not sure what you mean:confused:Yes they look the same if that is what you are looking for. If there is any difference it would be in the smaller blade, there is a little bit of play in the bottom when hooked up.

    Do we all agree that I should go in from this area, and not the back:confused:

    Do you own a volt/ohm meter?

    No, but I can get one:D Be patient with me F1nut, I know nothing when it comes to anything electrical:eek: When I get this, I assume I am checking to see if they come out the same, hense the term continuity. I am catching on!! Should I just leave things as is until then??

    Roger that, no problem.

    When you get one, set it to ohms. Touch the red lead to one large blade and the black lead to the other large blade at the other end of the cable. It should read zero(s). Test the small blades the same way.

    We'll proceed after you get the results.

    Something you can check in the meantime. Remove the binding post plate (on the back) from the speaker marked Right Channel. I want you to look at the color of the wire going to the large blade (top), it should be blue and the wire going to the small blade (bottom) should be green.

    Good advice here,, be sure to follow the instructions Jesse left in the above posts regarding the b/b cable, hopefully it's something simple/easy. I don't know why,, but I'm a pin blade guy;),,, good luck and let us know what you find.

    A long time ago, when I got my first surround sound system, I hooked it up backwards. Thinking that "left" meant the left side from back of the receiver, and "right" meant the right side from the back of the speaker. It took me an hour or so to figure out why everything sounded so ****-backwards.:p
