Hi Guys
I have this home-made cab that I bought ages ago - I bought it as I wanted the lovely old Baker speakers in it. Decided to leave the drivers in the cab as it is extremely well made with ply even though the tolex job is rubbish.
It has 3 output jacks on the rear of the cab.....a L and R on either side of a centre jack which the guy said was 15 ohms. So I rightly/wrongly assumed the speakers were 8 ohms a piece and the jacks were wired so that you get the left speaker on its own in the L jack and right on its own in the R. Individually I assumed the load was 8 ohms. The speakers do have 8 chalked on the rear of the cone so I assume they are 8 ohms....there's nothing about resistance on the labels.
However, I thought I really ought to confirm that the speakers
are 8 ohms and also that the wiring to the 3 jacks is as it should be. So......can I check resistance on the speakers to confirm they're 8? Can this be done with a meter?
Also, from the photos below, does the wiring look correct given the layout of the jacks? The pink wire goes to the positive terminal on the speakers and the green wire to negative. The pos/neg from each speaker go to the two outer jacks.
Cheers
Guy

As I don't have a 4 ohm out on any of my amps, they're all old, I think it makes more sense just to wire it to 16 ohms via a single jack and leave it at that. That was my intention when I bought the cab, to remove the speakers, wire them to 16 ohms and load them into another cab.
Would it be OK to use one of the existing stereo jack sockets or should I install a mono socket?

I'm not sure I quite understand how to connect the outer jacks in parallel. Wiring the speakers in series is a doddle, even I can do that, but not quite sure how to wire the jacks in parallel and then the speakers in series. Could I possibly ask you to explain how I wire the jacks in parallel? I'll then re-do it all and, as you say, I'd then have the extra option of running another amp with a single 8 ohm jack.
