I called Polk technical support and they told me that maybe one of the wires is connected to a negative instead of a positive or vice versa. However my other receiver wasn't a problem after I did the Audyssey calibration. The new Audyssey calibration must be more sensitive to what you are talking about.
I use monster speaker wire and never really payed attention to what ends were connected into positive or negative. The speaker wire looks the same on each side.
If my next receiver has this problem then I will have to follow the wire and make sure each end is correct for positive and negative connection. The good news is I don't have to buy all new speakers - just have to make sure they are wired perfect.
You mean you did not take note of my first post to check phasing to speakers!
One speaker out of phase wired incorrectly will ruin performance!
Monster cable is marked.
You MUST pay attention and have every positive on the receiver go to every positive on a speaker, and every negative go to every negative.
This is basic and essential to every system.
If you did not pay attention, then statistically the chance of you having a serious wiring error is almost 100%, and Audyssey caught your error or errors
Now I'm going to be blunt with you about this, and tell you that.
1). You have wasted my time and that of anybody who reads this thread.
2). You have wantonly cost Vann's money and Onkyo. They will take a loss on this. Onkyo if it is returned to them will have to sell your unit as a refurb after going to the expense of checking it out.
3). Negligence like yours costs everybody money. Yes, you have been negligent, extremely so.
Honesty requires you tell Vann's exactly what you have done.
I think they can legitimately sell that unit open box, but it will still be a loss for them.
The bottom line here is that we all have to use due diligence and look out for each other.
You have not even come close to using due diligence in this matter.
