I've always wondered (and dreamed) of a speaker cabinet made of granite or

I seem to remember Popular Electronics (I think) having
an article where you made the cabinets out of a section
of flue liner.

It was made from glazed tile sewer pipe. That was the DrainPipe 8
speaker.

My father and I built one (not two as this was in the daze before
stereo). It think I was 15 or 16 years old at the time. I vaguely
recall that it sounded great, but my mother had aesthetic objections.
The sound also coupled nicely to the floor and neighbors downstairs
also voiced their objections. The only part I really remember was
watching someone haul off the monster to who knows where.
