Question for the crew regarding extensions cabs. I bought this Fender 112 extension cab and of course I can't leave well enough alone. It won't quite swallow 2 12" speakers, but with a modified baffle I might be able to get one 12 and one 10 in there. Got me thinking not only about mixing different sized speakers (which seems like no big deal), but also about the larger topic of mixing different speakers altogether. I know some guys have done different speaks on their twins, and there's probably something to it. At the risk of being the kid at the spice rack, just throwing random stuff in the pot. I have a hard enough time choosing one speaker, let alone the cocktail of two.
