Howdy. So my brother is going to build me a 2 x 12 speaker cab. I would like the option of running one speaker for certain situations and both speakers for other situations. Im not entirely sure but I think I could run them individually out of my mosvalve, (this is all new to me) but then im dealing with tweaking both channels. Big deal? Maybe maybe not. Idk. Or, his suggestion was to simply add a switch to shut one of the speakers off when I wanted to. And secondly should I have him add a baffle between the two speakers that can be removed accordingly? Any thoughts or opinions would be greatly appreciated.
I don't think you really need a baffle. You can have two separate jacks, one for each speaker, and run the amp stereo, there wouldn't be much need to tweak anything, just keep the two volume levels the same. Plus it would give you the opportunity to run effects in stereo if you wanted. Having both wired in series or parallel but turning one speaker off would change the load on the amp so you probably don't want to do that. Others can comment, I'm sure.
Not sure what the benefit would be vs. just running both all the time and turning the power amp down, though?
