Can anyone tell me if D130Fs and D131Fs suffer severe high frequency loss as compared to D130s and D131s?

I seem to have lost a beautiful "chime" that I once got from 2-D131s, when I changed to 2-D131Fs(original cones) in a Fender guitar amp. Or am I imagining this?

And should I avoid D130Fs in my C36 cabs with 075s?

Thank you,
Darrell
