Altec 604 E reconing options.

Seems reasonable, what with its higher Fs, i.e. less moving mass, though I figured Altec would have tried harder to maintain its tone a bit closer between models.

Less moving mass and technically larger cone. The surround on the C is not near as large as the accordion surround of the E. I would also bet there could be a noticeable difference because there is so much less coating on the C's surround as opposed to how much is stuck in the grooves of the E's accordion design, weighing it down. I thought maybe they went to the accordion design in an effort to be able to claim the ability to handle more watts? which is pretty much what was happening at the time. everybody was going into the "I need more power" age. or they thought it was a better choice for the Solid State age.
