Actually KEF is driven by a scientific narrative . To sell everyone has to present a story and a brand , it is the least bad alternative
As a byproduct actuall science are done , good for all .
But as the paper says there are bulkier old methods that results in bigger (unsellable ) speakers , so no one uses this kind of aproach in practice .
If this aproach make it happen in actual comercial speakers good ! Thumbs upp from me .
An uneven figth for todays speaker makers it has to be small for the sake of being small , if you can turn that to your advantage that's really good.
* The good thing this smaller damping system may have desirable properties that old solutions don't have ?
* Bad thing , resources spent at "Figth against nature" ! Same problem as small subwoofers (just get the bigger box and problem solves itself ).
