Hey! So, I am in process of loading my Orange 4-12. It is going to take a while. As of right now, I am only playing through one speaker that is loaded in the cab and the whole cab sounds fantastic. I turn it up and there is sound everywhere. It is not like a regular 4-12 that is fully loaded of course, that is going to be beamier. So this scenario right now has me wondering about porting... Moreover, the legitimacy of those cabinets that are 1-12 but sized like a 2-12, and the 2-12 that are sized like a 4-12. Makes me want to leave 1 speaker out of the 4-12 at the top for just this purpose. I figger that is goint to be my stealth answer to "control freak" soundguys syndrome as well. I will simply put the mic in the port and tell them that I like "this" speakers sound the best. Perhaps I can turn my amp up a little more :BEER Thanks, M.E. Edit: those cabs are called "detuned" cabs. I am going to look into the theory of them.
