A 150-4c voice coil question

[NickH]

Does anyone know the dimension of the voice coil for the 150? Specifically the coil height.

I'm guessing back in the 50's the d130, 130, and 150 had very similar coil dimensions. But I'm not sure of this. I'm guessing its close to .3 inches but I need clarification.


Were those old drivers were slightly overhung?

Thanks,
Nick

I'm looking for the coil height. I think its .3 inches but I'm not certain of that.
