Re-wired my Ashton Quad Box.

I wonder if when your speaker cabinet was originally wired, the speakers were out of phase, and when you rewired it you corrected this and fixed the sound. Just a thought, as I can't see how the parallel-series method would cause any issues if done correctly.

It is entirely possible that at least two of the speakers may have been inadvertently wired out of phase at the Ashton factory, and I corrected it when I did the wiring, the cab did sound good before doing the wiring when I tried it out with my Super Twin amp, and I didn't notice any phase issues with it before.

I have tried the cab out with my Super Twin amp and the Marshall after doing the re-wire and it seems to work really well with both amps, there's a low-end resonance that I never noticed before, and yes, I did make sure I had all the speakers correctly phased while doing the re-wire, I used a blue sharpie to mark the + and - terminals on each speaker.

Both the Series-Parallel and Parallel-Series wiring methods should result in the exact same speaker load impedance, assuming that all four speakers in each case are 8 Ohm speakers, it's possible that with the re-wiring both my Super Twin and Marshall amps are seeing the proper load impedance being reflected back into the output transformer, although yes the phasing of the speakers may also have something to do with it too.

I've decided to keep a very open mind about the whole thing.
