OK, gotcha. Thanks, Arny. Now what about things like concrete
cabinets? I have a small pair of Rauna speakers that I like and they
are made of concrete. Even though they are "bookshelf" size speakers
they weigh about 45 pounds each. Would you consider that type of
construction to be way beyond the point of diminishing returns or
would the significantly heavier concrete walls just be similar in
effect to the extra bracing you mentioned?

That depends if you have to pay the shipping cost on them, and if you
have to carry them around a lot.

The holy grail, of course, is a lightweight cabinet that is nonresonant
and can stand being dropped repeatedly. We don't have this, but the
carbon composites get better every year.
