Speaker base - what material is best?

Hey!
I just bought a pair of monitor 4 acoustat speakers - electrostats. the bases are the ugliest things i've ever seen in audio: black fiberglass with plywood bottoms. jeez. I took the speakers off the base and they're currently on the floor. I'd like to make bases for them but don't know what material to use or where to get it. any help is much appreciated. i'm thinking crazy like all stainless steel i might find in an architectural salvage yard or maybe find some MDF and cover it with laminate. Or?? I'd like to keep the whole eames era look going if possible.

As always, thanks in advance.
