Just realised the song is "Up the Wall". For wall speakers. All part of the plan?

I've seen this technology used with wooden floors. No need to cut up surfaces, these drives can be easily attached to the surface (either side) and wired up. Job done.

Very easy to add to a Deck. No need to have a 'Pet Rock' speaker sitting in a corner with a grill on the front.
