Hi everyone, I have a 212 that I'm going to be loading with 2 8 ohm Celestion creamback neos, I was wondering if there's a way of wiring the back plate to have four inputs for a few different options as I would like to be able to use it with 2 amps at the same time and have some impedance options when using it in mono if that makes sense? kind of like the marshall 1960a cabs but without the stupid PCB, would I need some sort of switch like on the marshall? so the inputs would be
1 - mono (series) 16 ohm
2 - mono (parallel) 4 ohm
3 - left speaker 8 ohm to be used with amp 1
4 - right speaker 8 ohm to be used with amp 2
any help you can give me would be greatly appreciated. Cheers.
George.

Probably the best solution is to have two jacks each wired to each speaker and a switch to connect the speakers in series, which would give you a 16-ohm mono cab - usually the most useful. Then if you want to use it at 4 ohms, connect two speaker cables from the amp (assuming it has two jacks) to both speaker inputs.
Alternatively, use the jack switching to connect the speakers in parallel - this isn't as bad from a reliability point of view because the failure mode still means the amp has one speaker as the load - and an external series cable or box to give you the 16-ohm option.
Simplest of all is just to fit two completely separate speaker jacks and get one of these - https://www.thomann.de/gb/palmer_cab_m_merger.htm
