JJ offered a clever theory, but looking at the description and photos of the Comet at the AQ site I don't see anything suggesting that the gauge of the treble wiring is extremely thin,
Don't know how clever it was but after 454 posts from lots of experts I can only come up with what are obviously long "reachs" for a possible explanation for the bass issue. I agree with Al that the wire that "biased towards high frequency finesse" does not look thin enough to be a problem however I am not well versed in the AQ wire topology or how the battery bias may be working if hooked up wrong. Also I came to the same conclusion, now that I know the cable, is that the only miswire that should still work should effect the bass from the start, not change with playing time.
Also there has been some discussion of the PSB's having a low impedance. I have not seen a graph but if that dip is in the bass range it would, IIUC, not take to much of an increase in wire resistance to effect the damping factor. IMO, from the recordings that were sent out, it is not a quantity of bass issue it is the quality of the bass that changes.
Again, a way out theory, but without physically seeing the internal construction of the speaker wire it's all I got at the moment.
