Think of the room as the second, bigger speaker cabinet (one cabinet, the room, is on one side of the driver and the "real" cabinet is on the other). So if cabinet design is important to you, so much so the room. And if you have open baffles, the room is really the only cabinet.
IMO more drivers is a sign of bad things. Just take multiple midrange drivers for instance. Sound waves emminating from multiple sources can't be good for imaging. And no two drivers will behave or sound exactly the same. Except for some small extended range drivers any driver should be able to handle realistic playback levels in "normal" sized rooms. Same to be said of the performance of multiple amps.
I agree with above, I'm much more interested with 95% solutions at 5% of the cost of the "ultimate" (whatever that is) and that many of the high end stuff doesn't float my boat. Its ridiculous how poor of rooms nearly all retailers use to show off their wares. My listening room (without treatments yet) cost less than $500 above typical construction. Insulated double stud walls, mineral wool drop ceiling with insulation above, flexible/insulated ductwork, exterior fiberglass door, dedicated circuits, cryo'd hospital grade receptacles, and of course the room dimensions in the correct proportions. IMO worth 100 times more than investing the same money into upgraded interconnects for instance. I can listen when I want, at the volume I want, to what I want, without hearing the TV, dishwasher, etc. (or the family hearing me).
