There was the Acoustic Precission Eikos FR-1 produced some time in the 90s and the result of a collaboration between Tom Evans, Patrick Handscombe (presumably not the cricketer) and Ted Jordan in the UK. It was a single driver in a polystyrene foam box with a thin skin on the outside. It worked very well when I heard it at Tom’s place in Wales and my local hifi shop carried it for a while but I don’t think it sold that well. People prefer something more substantial for their money it seems. The finish wasn’t very robust I’ve heard.
