So it took a little while to figure this out but I got it working. So now my cab is set it to run various combinations and impedances. I can run two amps at the same time. One amp to 2x10" at 4 or 16 ohms, another amp into 2x6x9" and 12" at 4 or 16 ohms. Or one amp into all speakers at 2, 3.2, 8, 16 or 32 ohms. Not that I would use some of the higher ohms (16 - 32). Switches and jacks are mounted on a temp board for now.

Very cool - I just did something similar, though much simpler, my first time wiring something in series. Hope your amp likes it! ---------- Duke Berryman - Chicago blues, harmonica, guitar

Since you have different makes of speakers, do you check their phase?
Back in the day, we would take a 1.5 volt battery and apply a test voltage to make sure all the speakers were going out at the same time. Or maybe everything is standardized today and it's no longer needed?? ---------- theharmonicaclub.com (of Huntington, WV)

Jim - you are right to bring it up. You should never assume that "+" on one speaker means the same as "+" on another. It SHOULD - i.e., a positive signal on the + side should move the cone out - but it isn't a given. I've even seen 2 Weber speakers where one was the opposite of the other. ---------- *************************************************** /Greg

Why would I do a silly thing like that... Of course I would! I wouldn't take the time to wire all this up and not check the phase. I all ways check my speakers.
All done
