This has been driving me nuts for a couple of hours. What was the name of the speaker, produced in the seventies, that was a large dipole with a wooden frame, a soft membrane, fabric or rubber as I recall, with a voice coil fixed to the middle of the membrane. A brace held the magnet/voice coil assembly, the membrane did not have to support the weight. They were four feet high or more, quite large.
They were around in the early seventies, at least.
Any help would be appreciated.
