Orange cabs and ohms

Postby Krohurte on Thu Dec 08, 2016 1:33 pm

Hi,

I tend to get me a PPC212 or a PPC412. They all seem to be 16ohms. But I don't find any info about the ohms value of the individual speakers and/or if they're wired in series or parallel. I wonder if it's possible to rewire them from series to parallel (or vice versa) to get them to be an 8ohm box to run together with my 8ohm combo.

I'm afraid you're out of luck. :(

AFAIK the PPC212 is a pair of 8 Ohm speakers wired in series. If you wire the two speakers in parallel you'll end up with 4 Ohms. There is no way you can wire this as an 8 Ohm cab.

Again, AFAIK (and if anyone knows differently, please correct me) the PPC412 consists of four 16 Ohm speakers, wired in what's known as "series/parallel". In other words, two of the speakers (let's call them Pair A) are wired in parallel, making an 8 Ohm pair. The other two (Pair B) are also wired together in parallel, making another 8 Ohm pair. Finally, these two pairs are wired in series, resulting in a total load of 16 Ohms.

With a cab that contains four 16 Ohm speakers, again it is impossible to make it into an 8 Ohm cab. You can have:

64 Ohms (all the speakers in series - I wouldn't recommend that!)
16 Ohms (as described above)
4 Ohms (all the speakers in parallel)

The only way you're going to get an 8 Ohm load using Orange PPC cabs is by having either two PPC212s or two PPC412s. Expensive!

thanks!

seems to me the reason why most guitar cabs are 16ohms then...

Most BRITISH speaker cabs are 16ohm. American ones seem more likely to be 8 or 4 ohms.

Orange cabs are usually four 16 ohm speakers wired series parallel to make a 16 ohm 4x12 cabinet, and as said above, two 8 ohm speakers wired in Series for a 16 ohm 2x12 cab.

You can wire a 4x12 as x2 16ohms in parallel with a switch so you can use stereo 8 ohm like the modern marshals or 16 using all 4
All bleeding stops.......eventually.

thanks, I have to do some other research and might get back on this.
