Length of speaker cable effect bass response?

Any chance of moving things back to where they were ?

The speakers remain in their original location. Could the gauge of the bluejeanscable be the cause of lossing bass response or perhaps impedence problems? The cable is 14 gauge (Canare 4S11)

Any possibility one wire may have backwards polarity?

I second HifiTime's question. If the speakers are wired out of phase relative to one another, or if the low frequency and mid/hi frequency bi-wire connections to either speaker are reversed relative to one another, there will certainly be major audible consequences including attenuation of the bass.

I doubt that the length is excessive enough, or the gauge small enough, to result in attenuation of the bass. The resistance of a 60 foot round-trip run of 14 gauge wire is approximately 0.15 ohms. That might be marginally significant if the impedance of the speaker at bass frequencies drops down very low, but my impression is that most or all Usher models do not do that.

Time to go to Home Depot and purchased some 12 gauge speaker cable. This is a very inexpensive way to see if it is your present cable, which could in fact be defective. A quick check on the latter would be to switch the cables you have. But in any event, be bold and go to Home Depot to test whether the whole cable game is hold you back.
