" Your approach seems much more logical that the cabinet itself would have little to none and also dissipate any vibration."
Which is basically the thinking behind the classic BBC designs now inherited by companies such as Harbeth.
Light but rigid materials are used so that energy is not stored by massive construction only to be released later to colour the sound. BTW, they are indeed made from Baltic birch ( viz.bare) but in plywood form not as solid timber planks. Their implementation of this concept deals with vibration by the application of damping pads.
The difficulty with foam as a cabinet material as I currently conceptualise it, is with maintaining rigidity across the audio frequency range. I have difficulty in visualising a successful foam baffle for example, both in providing a datum for the cone movements and with the simple question of fixings (adhesives?). The question of durability also occurs.
