Graphene spray and ...

With manufactures expressing that success with graphene is very dependent on application, some time and experimentation will likely be required.

It may have a benefit in speaker driver surrounds as its structure in rubber aid in rebound. We've also seen carbon epoxy implementations that may add to driver diaphragms that are carbon composite. Likely reduction in distortion and further frequency response range before breakup. Some speaker cabinets may benefit with its application.

It was thought that graphene could be use in voice coil as yarn had been recently developed, but now that stanene outed as graphene's tin derived cousin and it shows now resistance at all until 100C, it may become bypassed as a conductor.

The Mat-Sci lab is going to be an interesting place be and I have little doubt some will end up in audio products at some point. Might be a bit until affordability makes it more than just a lab experiment though.

Hey jeeter, not better; but, maybe 'faster' ?? lol

Geoffkait, once we're talking faster than the speed of light-I think it's getting "verry interestink" per Sgt. Schultz

Thanks almarg.
If new graphene technology can make our 
preamp,amp and digital equipment 'faster' I think 'cleaner' signals will be the result; giving us better sound.

Mmeysaroch. Very interesting. I think distortion reduction and the extended
frequency response w/o breakup would be terrific benefits. Luckily there's so much research going on I think we'll get products fairly soon (not the current products that advertise graphene but are probably using plain old graphite ; as there's no explanation about their manufacturing processes-which have to be discussed to be believed).
