I read that 5 co. offered kits -Jensen, Electro-voice, University, Stephens and Altec. This last was (supposedly) a consumer version of the famed 604.
Question -were these really the same as their pro counterparts ? And did they use compression drivers ? Or was it just an isolated tweeter placed in cone ?
Thanks...

- no, the diaphragm is probably about 2.8" in diameter - it's NOT a direct radiator - mhardy6647 15:05:21 03/25/16 (0)
