Marine subwoofers are a thing..., but i wonder i blew the dust out, clearcoated salt. where the mounting surfaces were, heatshrunk connections and dunked the driver in oil before mounting if it would last forever in a dry living room.
Getting no air leaks between the bricks might be a pain.

I imagine a lighted saltwoofer would look a bit like lamp pics. It's far down my list of projects so if it ever gets done will be a while from now

Connecticut's average relative humidity is near 70%, not considered "dry".
Unless you are de-humidifying to below 60%, the hygroscopic salt bricks may pull moisture from the air (and weep salt crystals..) unless sealed.
There seems to be many sealants specifically made for Himalayan salt bricks, if you completely seal them, the speaker should be OK. That said, the tools you use to cut the bricks will probably rust out, but compared to the cost of the bricks, who cares 😉
