Scott, I tend to think of IB in simple terms, basically, literally, as an "infinite baffle", the idea being that there is no load other than "open air" on either side of the driver diaphragm, and there is no "baffle step"/acoustic short between the two sides of the diaphragm, because the two sides "never see each other". IMO, the idea of using IB is to clearly hear the driver's "voice", for whatever that might be worth, and the "right" driver will be able to articulate with consistency through its range. Given my simplistic notion of IB (at lower frequencies), I don't understand/accept the specific ideas of differential loading you are talking about. I have experimented with "wave guides" that are really just curved baffles, with some "benefits" down to lower MF. True LF gain from a driver requires a horn, or "adding" from a vent from a "controlled environment. Whatever, I do not think of IB as a way to "push" LF from a given driver. FWIW, I don't think one gains much from thick-coned, long-throw LF machines in an IB enclosure, so why dedicate the space for it? OTOH, since it all has to be tested, anyway, and I have had my share of pleasant surprises in hi-fi, I will add that there's no way to be sure until you try it.
