How does the G12c/s handle treble?

Assuming I run a bright amp or EQ my tone to have a lot of higher frequency content, how does the smooth cone G12 handle those frequencies? Like, are there drop-offs or would you get some weird cone cry etc.?

I’ve had very good luck using the C/S to tame very bright amps … it is a dark speaker, but when paired with a very bright amp … the result is nice, smooth top-end … or at least that’s been my experience!
