At 27g, the B&C 320K/C-A has some of the lowest Mms you will find in a currently available 12" driver not marketed as a "guitar driver", outside of some boutique Supravox offerings.
"guitar drivers" would be of interest but I'm after an FR.
My only experience with ultra low mms driver was the Sica 10D1CS, another FR with slightly lower mms/sd ratio spoiled by a very weak magnet.
With a Qts of 1.56 it was unusable as a sealed FR but provided some insight, this driver has an airy and liquid midrange tone that I quite like however peaks in the upper end were particularly pronounced.
How much of that is down to the unsually low mms or the overall characteristics of the drivers is not known.
"liquid" is a term associated with low mass planar headphones (versus the "granular" sound of dynamic headphones) and that is sorta what it reminded me of
You can tell the cone is light just by touching it, it flexes like an A4 sheet of card and I am presuming the B&C cone would have to be similar enough.
With regard to damping, break up behaviour, LF/HF performance etc. what are the potential compromises and gains with a very light cone?
The only glaring difference you can glean from the spec sheets is much reduced power handling spec compared to pro drivers in the same size class, which suggests that distortion rises quickly with power... that is a good trade off for home users pushing only a handful of watts into them.

Directly effects Fs.
If its truly ultra light, if it's used for bass, I imagine quite a lot leaks through the cone. That would be interesting to look at.
Very best,

Hi, in fact, this speaker is not much suitable for hi-fi. Frequency response is very strange.
In addition to strong irregularities (almost 20dB from 85db @800Hz to 105dB @3kHz), it enhances frequencies above 2kHz and rolls-off quickly below 70Hz
Without proper equalization or some passive filter work, it will not sound good for listening recorded music.
Speakers for instruments, especially for guitar, are another story.
They color the sound but, in this case, the user expects that effect of coloration which intentioanlly changes the sound, makes it warmer etc.
It's part of the guitar sound (guitar+amp+speaker=final result).
In terms of T/S, we have to be more holistic, by considering the set of parameters, rather than an isolated one.
It is a very odd looking FR graph, it may be in part how Sica measured their older generation of drivers
See similiarity in response of this small 5" driver from them

"low" or "high" are in the eye of the beholder. It's one number traded-off among many to make a certain tool for a certain job.
If you were to ask someone with widerange drivers of the 50's, 20-something gram (curvilinear) cones (rated for maybe 35W) would be normal.
