Mic'ing the cabinet is strictly for sound reinforcement. As a musician the rig and it's details should be dictated by his or her own ear first, the mic is only there to try and capture that. The size of the cab matters because there are waveforms coming out of the front as well as the back. Closing off the back eliminates the rear air from moving out and meeting the front air. Closed back, half open back, 3/4 open backs and completely open backs all have their own responses because of this. For instance, with any of the open back cabs the depth is a consideration for the speed at which the back air reaches the front air. Kimock is known to be hip to this! That said, speaker choice plays a big part in dictating what attributes are needed for a cabinet. If you dig enough on a particular speaker, the professional companies have already put in the time in figuring out just what is needed for a cabinet to mate it with. Ultimately though it is always up to what the musician wants out of a speaker(s) and the cabinet(s) it will go in. Remember, the sound man does not have a job if there are no musicians to reinforce. And good musicians know what is needed volume-wise, both stage and house, to achieve the dynamics they are trying to create.
