My buddy and I both have a Marshall 1965a 4x10 cabinet, both loaded with 8 ohm Celestion 10" Greenbacks.
We were A/B'ing them, because I thought mine wasn't sounding as good as I thought it should.
Same amp, plugged into each cabinet, his was noticeably fatter and more aggressive sounding.
Opened up my cab and checked the wiring. Standard series/parallel, all speakers in phase, all speakers working.
I noticed that the speaker positive was connected to the barrel connection on the jack. Seemed like it should have been on the tip, so I switched it and tested.
Wham! My speaker cab sounded just like his. Fat, tight, aggressive, punchy. Everything it was lacking.
Now I heard that this does not matter, that it only matters when you have another speaker cabinet connected, for phase reasons.
And I know this wasn't a double-blind test, but two guys heard the same thing, and we did have a "control" so it was somewhat scientific.
Anyone want to comment?
