Is there any significant difference, or advantage to running a 4 ohm speaker plugged into 4 ohm output jack vs using an 8ohm speaker plugged into its appropriate 8 ohm output jack? In my mind, the load matches the tap on the transformer and there should be no tonal or dependability issues..?
With my DB4, I'm running two 2x12's with (2) 8 ohm speakers. In series, they are louder and a bit hairier, and seem to break up a bit earlier. In parallel, they are quieter and smoother, almost like hitting the half power switch on the back. There is also a noticeable decrease in the amount of distortion, whether it's coming from the speakers or the amp, I don't know. This is the case with both my ASW KTS70 loaded cab and my Alnico Cream cab.
I was always under the impression the load the amp sees can change tone. It's more noticeable if you're running relatively uncolored speakers like the KTS70's. I notice less of a difference when I switch ohms and wiring in the Cream cab.
I've been wired in series for so long, I should go back to parallel and give it another whirl.

A DPDT switch should allow you wire it to switch between 16OHMs Series and 4OHMs Parallel instantly. Just make sure to plug into the correct speaker out! Should make comparison easy with a switch taking seconds.
