Wiring for switchable/multi input 4/16 ohm cab
Hi
Just so I end up grabbing the right parts from Jaycar can someone post a diagram of how to go about wiring a 2x12 with 8ohm speakers cabinet such that I have an input (or switch) for 4ohm or 16 ohm?
I'm guessing I'll need some sort of switching jacks to open one circuit when the other is closed.
Thanks

Yep, a double throw switch (dpdt) and wired like this ignoring the out

i did find that image but the 'in' and 'out' confused me.
Is the out an extension speaker out? or are those the two inputs?

You can use either. Just remove one and call the other SPEAKER
When faced with quality, I recognise it every time.

Re: Wiring for switchable/multi input 4/16 ohm cab
would something like this not be rated for that sort of heavy work? Just seems a slider might be a bit less likely to catch on stuffGrantB wrote: ↑Sat Jul 15, 2023 12:18 pm Yep, a double throw switch (dpdt) and wired like this ignoring the out

Re: Wiring for switchable/multi input 4/16 ohm cab
Remove either the IN or OUT from the circuit and relable the remaining one speaker

But I could choose to leave it in and it would be an extension speaker out ?Jay wrote: ↑Sat Jul 15, 2023 1:36 pmRemove either the IN or OUT from the circuit and relable the remaining one speaker

Re: Wiring for switchable/multi input 4/16 ohm cab
Correct, but you would have to 'recalculate' impedance as the external connection is wired in parallel.StrummersOfThunder wrote: ↑Sat Jul 15, 2023 1:39 pmBut I could choose to leave it in and it would be an extension speaker out ?
Examples
DPDT set to 16 ohm. Add 16 ohm external speaker. New impedance is 8ohm.
DPDT set to 4 ohm. Add 16 ohm external speaker. New impedance about 3 ohm. (64÷20)

Gotcha. I'll leave it out.Jay wrote: ↑Sat Jul 15, 2023 2:08 pmCorrect, but you would have to 'recalculate' impedance as the external connection is wired in parallel.StrummersOfThunder wrote: ↑Sat Jul 15, 2023 1:39 pmBut I could choose to leave it in and it would be an extension speaker out ?

Or.... Could you have it to access one speaker at 8ohm?

No, for that see thread below. I ll see if I can dig that photo upStrummersOfThunder wrote: ↑Sat Jul 15, 2023 2:15 pmGotcha.
