Solid wood and concrete speakers

[Spectrum]

This is about hi fi speakers and likely has no application to bass cabinets, but it's very interesting and satisfying to watch people work who know what they're doing. Towards the end of the video the concrete speaker cab is something I've never seen before.

There are (or at least were, dunno if they're still in business) kits sold for making bookshelf speakers out of cinder blocks. I imagine they can work well if the components are decent. At small bookshelf size, though, I imagine any plywood over 1/2" thick is going to be plenty rigid enough and the added mass and rigidity of a cinder block doesn't bring a whole lot of benefit, except maybe a cost savings if you happen to already have a couple cinder blocks lying around.

A timely topic and Tom Hidley just passed away. His passion was designing audio spaces, and at one time was using concrete-encased playback speakers in studios. Check out this story: Remembering Tom Hidley, 1931-2025 - Mixonline
