Measurements of RCA Lc 1a (Olson design)

[Freedom666]

Does anyone have or know where to find measurements of this driver?

Mostly interested in burst decay and phase response

40ies design

Astonishing blast from the past. Best Olson/RCA Lab could make..... 1950???

Do you have one?

No just very curious how it measures with modern analysis like burst decay.

And phase response because of time aligned tweeter in the middle of the big driver

To make a paper diaphragm more stiff by structure is a good idea but rarely adapted. Here Fotos of new Fostex fe 208 sigma
