I was wondering if anyone had used plate steel to construct a subwoofer enclosure? I would think that by using 3/8"-1/2" plate steel the structural rigidity would be the best that one could get, especially after welding some bracing inside the box. I would also think that the resonant frequency would be quite low, if there was any at all?
Has anyone built a box from steel, welding the joints ect? I realize that a box like this would be quite heavy, but wouldn't this be the ideal material?

I haven't built a box from steel, but it should be very good. you do not need it that thick. What you want is stiff, and braced such that it has a high resonance. If any (potential) panel resonance is well above the sub's pass-band it will never get excited, which makes it as thou you have a resonance free structure.
Do a search for GM's posts on the subject to get a better idea of a sensible thickness.

As you know audio is all about compromises. The less compromise, the better the outcome. So could you build a 2000lb subwoofer that needs to be moved with machinery? Sure. For what application? Is it worth it? (by the way my welding table is 3/4" thick old road plate...6'x4' or so. It's a pain to move. I can't even imagine constructing a braced (I beam bracing?) subwoofer enclosure out of it!!)
End-grain balsa laminated with fiber and resin:
This set uses class fibers.
An externally hosted image should be here but it was not working when we last tested it.

whats about ceramic tiles? Make usual chipboard box and glue ceramic tiles to all inside sides? would it stop most of vibrations? Ceramic and stone tiles are pretty hard material...

I would not recommend steel for an enclosure as it can transmit energy - ie vibrations.
Concrete and ceramics do not have any tensile strength ( or very little tensile strength ) and therefore can not transmit energy.
