I know nothing about speaker design, so didn't really follow the concrete wall idea. Is the thought just that a speaker should be in a rigid non-resonant enclosure?
If so, it sounds like a quick and easy backyard project for a DIYer (not me). Just create a simple mold with spaces left for the drivers and the wiring. Fill with concrete and allow to harden. Put in driver and wiring and try it out...
I can't believe it would sound good, but it could prove out the concept..?
