I note that Monitor Audio use a dampening ring (similar to accuton rubber dots) to help prevent and dampen all the unwanted energy from the ringing of their rigid drivers. My ears are very sensitive to this type of coloration which is why I tend to defend old school pulp paper and damped fabric cones of the type generally preferred by Wilson. An internally damped driver (made of material that is dead and will not vibrate) will not ring like a bell and therefore it will better convey micro detail in music (timbre). So while you are dismissive of decades of engineering and proven track records as outdated, I will continue to enjoy better sound from solid designs using well understood principles that have withstood the test of time.
here is the description of how Monitor Audio reduces unwanted vibration:
"A new innovation in every driver replaces the usual rigid coupling of driver and voice coil with a pliable one. This ‘Dynamic Coupling Filter’ is a nylon ring ingeniously calibrated to be rigid up to the crossover frequency, and to act like a spring above it. In so doing the DCF helps to dampen surplus high frequency energy produced by the driver. It’s also perforated to encourage voice coil cooling and release air pressure from behind the cone for maximum driver efficiency. Result: more natural sound."
Test of time is important. A voice coil runs at over 100 centigrade - how to ensure the consistent elastic properties of that nylon ring as it is "baked" through thousands of heat cycles and also ages? No doubt Monitor have looked at this, however, time will tell. Just like Ferrofluid dries up - how robust and for how many years and how consistently can a chosen design platform perform?
