Does anyone have a multi speaker cabinet where you wire it in 4ohms for certain situations and 8ohms in others?

What multi speaker cabinet can be wired to either 4 ohms or 8 ohms? Short of cabinets with dual voice coil drivers I don't believe this is possible.

Not if they are telling you the truth...
I have multiple speaker cabinet*s* that I can wire in either 16, 8, or 4 ohms. They are 16 ohms each, so I can use 1, 2 or 4 depending on how much air I want to move.
I guess "multi speaker" kinda gives the connotation that I meant like a 15, 10 and a horn. But meant a normal cabinet like a 2x10, or 2x12
There's no 2x10 or 2x12 that can be both 4 ohms and 8 ohms.
The closest thing is 4 and 9 Ohms, if you use six of 6-Ohm drivers.
That's because 6*3/2 = 9 and 6*2/3 = 4.
It's a complex wiring job, probably nobody has ever tried it, and it's not worth the trouble. More of an amusing math puzzle than a practical idea.

It doesn't work that way.
Say a 210 cabinet at 8 ohms total uses two 4 ohms speakers in series. Your option is to open up the cabinet and rewiring the speakers in parallel. The resultant total load would be 2 ohms, which is too low for the majority of amps on the market.
The other possibility is two 16 ohms speakers in parallel but rewiring them in series would result in a total load of 32 ohms, which no-one wants.
It's a total PITA to open up a cab and rewire the speakers and there's really nothing to be gained by doing so. Each time you open the cab you weaken connections, screw holes, etc.
Are there times when one wants to say…
“*** ever, man….”
This is one of those times, but I won’t….

)Yes, in a two speaker cabinet with 4 ohm speakers you could have either 2 or 8 ohms, with 8 ohm speakers 4 or 16 ohms.
I did modify a 4 X 12 guitar one time to be either 4 or 16 ohms using an Speakon NL8 connector. The NL8 jack in the cabinet had all the speakers directly wired to a set of connections, with two different plugs that with in the plug changed the series parrallel wiring.
In your OP you stated 4 ohms or 8 ohms. You could have 4 or 16, or alternatively you could have 2 or 8. How could you arrive at either 4 or 8? The math doesn't support that conclusion unless you're disconnecting one of the speakers, which seems ill-advised.
If you can come to a prime integer (2, 5, 7, 11 for example) the tone will blow your mind.
I modified an 8-ohm 210 into a 2-ohm cab (so I could draw ~400W from a 2-ohm capable amp, rather than ~200W into 8-ohms).
I also modified an 8-ohm 410 into (effectively) a pair of 4-ohm 210s (used it with a specific amp).
These were both mods, not switchable.

Epifani has their [Invalid or Expired Link Removed]. They are user switchable from 4 to 8 ohms, no wiring on the user's part, just flip a switch
