Just picked up an Orange PPC212 that's a little beat, but in good enough shape for $300, which is what I paid. The guy has it wired parallel for 4 ohms, but I need to put it back to series for 16 ohms. I've read some things about series being dangerous for a head if one speaker lets go, as the amp will see no load, since if one goes, they both go. Question is, how big a deal is this? I can't imagine it being that big a problem, since this cab was originally in series, and is a very popular cab. I have a Hovercraft Dwarvenaut on the way! Thanks!

True, if they are all wired in series that would be the case...but are you doing all four in series, or series/parallel, where you put the two pairs in series and then parallel them? If so, two speakers would still be hooked up I think...if not, it's a necessary evil...speakers rarely let go, you will have more trouble with the tube head I suspect...my two cents. IA.

In my experience a blown speaker is rare.

Imagine Marshall Blues Breaker (50 watts), they had a pair of 25 watt Celestion Greenbacks. A Vox AC30 (33 watts) had pair of 15 watt Celestion Blues.

You could install a DPDT switch so a pair of 8 ohm speakers could be switch to either series (16 ohms) or parallel (4 ohms).

I see it today. I was using my phone like most of the time. I checked it on my computer too and it didn't display. Maybe Hot pants crashed the site for a few minutes.
