I want to concentrate on building speakers!

Seriously. One of my obsession in this regard is building a speaker
where the only part you hear sound from are the transducers/drivers/
cones/whatever, NOT the material they're mounted in/bolted into.

How critical is that last factor - minimizing resonance? And should I
build them out of 1" thick steel plate or oak/other wood?
