Series or parallel? Pondering the wiring of 2x12s...


Can anyone tell the basic difference in sound with a 2x12 wired in parallel, as opposed to 2x12 in series? What's the common procedure? Do monkeys fly outta my bunghole?

Any input is welcome (as always), and sometimes necessary.

There should be no difference except for impedance. When spearers are wired in parallel you get (speaker impedance)/2 full cab impedance, when in series it's 2*(speaker impedance). So if you have 16 Ohm speakers parallel wiring is pretty much the only option.

Thanks for the info.

Although I think Eric Johnson might disagree and give an hour-long lecture about how vintage Marshalls seem to prefer this and this impedance with this & the other speaker combination...

Sorry, but Eric Johnson doesn't know jack about the physics involved. And in a blind test he wouldn't tell one wiring from another. I can pretty much guarantee that.

No offense to Eric, he's an awesome player, but sometimes musicians believe in totally ridiculous things (like George Lynch who said 220V 50Hz mains gives better tone than 115V 60Hz). For as long as it helps them play better, I don't object.

I think Eric's best one was putting one of his two Marshall heads onstage behind the speaker cab because "it sounds better that way"...

Oh btw did I mention that I believe in elves?
