Should I wire my 2x12 for 4 or 16 ohms?

Got the new 2x12 in, and it's getting a pair of 8 ohm speakers. Looks like I can wire them parallel at 4 ohms, and series at 16 ohms. Currently wired in parallel, just because that's how the cab showed up, but I'm thinking about switching it up. Does HCAF have a preference? Should it matter?

Here's another option



I used to recommend this as well.

BUT...if you're dealing with the out put from a tube amp (which is relatively fragile with regards to resistance) and switches (which can fail open)...it's too easy to fry an output transformer.


UNLESS....

You wire in the switch, hit standby before switching (cab ohm AND AMP OHM)...AND THEN REMOVE the switch once you've determined which sound you prefer.

:thu:

I wouldn't leave a switched cabinet hooked up to an amp. Bad times waiting to happen.
