Stewart,
Of course the material and construction of the driver influences the sound. Basically, hard material cones are less damped and tend to ring but can be more pistonic (broader frequency operating envelope) - allowing the use of small voice coils on larger woofers. Softer materials such as damped fabric cones often have the least coloration but suffer from a reduced operating envelope as the cone can break up and to have a good operating range they may need enhancements like more support from a much larger expensive voice coil.
There are are pros and cons to everything and then there is aesthetics and marketing (choice of material may influence buyers) - as you alluded, there are so many ways and combination of materials used to make the cones that the only logical conclusion is that it DOES matter.
BTW - the rubber damping dots on Accuton drivers - any idea what they might be for - could it be Accuton’s approach to reduce ringing?
BTW - I can hear the difference. You are blessed if you cannot as a variety of materials and a much larger number of speaker designs will work equally well for you.
