When I worked for Hegeman, we hand spun the aluminum speaker cones in a spinning die on an old, direct drive 16" transcription turntable. The turntable was out of a recording lathe. Bose basically stole Hegeman's design for the Wave Radio. The aluminum cones and aluminum voice coil could absorb a tremendous amount of power for an 8" driver. The cone doesn't flex, rather is moves like a piston. Stu's design is still being made after a Canadian company, Morrison Audio, bought the intellectual property from Stu.
My first ever turntable, back in the 1970s, was the innards of a disc recorder. I got a Coke crate, busted out the middle slat, turned it upside down, and set the turntable motor, turntable, and faceplate into the hole. Then I bought a tonearm and cartridge and hooked it to a stereo radio for a pre-amp and then to an old stereo and speakers. I used that for several years until I bought a stereo.
