Hi, please forgive this largish post, but I've been wracking my brains with this. I have 2 Jensen Mod speakers in a homemade cab, both rated 25W @ 8 ohms. What I would like is to be able to wire them up so that I can toggle between 4, 8 and 16 ohms. Obviously, 4 ohms would require the speakers to be in parallel, 16 ohms in series, and 8 ohms would just use one of the speakers directly. I know there are wiring diagrams around that already clearly explain how to wire up 2 x 8 ohm speakers for 4 and 16 ohms selectable output. But adding the extra 8 ohm option does my head in!

I've broken it down & I "think" I have arrived at a solution, but could some of you more knowledgeable amp techies please have a look?

Here are the 3 different wiring options (for 4, 8 & 16 ohms) --

And here's the solution (?) I came up with. I "think" it would work, however, it requires 2 toggle switches to route the signal path appropriately --

Here it is again with the 4, 8 & 16-ohm signal paths traced out in different colours to avoid (??) confusion of where I'm going with this ---

What I plan is a metal plate on the back of the cab with a couple of toggle switches and of course the mono input socket, something like this --

I "think" this is a viable solution, but to be honest I don't like the two toggle switches - it looks a bit awkward & ugly. Also you would have to be very careful to have the switches toggled correctly. But is this the only way to do this, do you think? Does anyone have any suggestions or ideas around this?

Thanks in advance.
