Yup it makes good sense at 4ohms, for sure.
But my current regular gigging cab is 8ohms...
And I'm about to get a Fearless F112 cab (which is also 8 ohms and before you ask, nope I'm not planning on pairing them up to get a 4 ohm load 😃)
I came across this rather 'on point' thread from a couple of years back which was very useful for my set-up-to-be and also a little bit fruity...
