I had a next door neighbor who bought a pair of Klipschhorns in kit form that I am pretty sure were from there. No ordinary speaker, but a folded horn design that somehow produced the equivalent of a 24 foot long horn for extended bass. (Double check me on the 24). They stood approximately 3 feet tall and very wide. Inside was a labyrinth, where the woofer was fully inside the cabinet, facing forward, but all the sound came out the sides towards the back wall.

The crazy thing was that the neighbor used a hand saw for all the plywood cuts. And it was perfectly executed.
