I don't think they currently have anyone working for them who's creative enough to make something to better the blades.
As good as it gets?
It's been over 5 years since the release of the outstanding KEF Blade 2 loudspeakers and not even a hint of a successor. Is it possible that the Blade 2 is as good as KEF can do with this design? Is it possible that the Blade 2 can not be significantly improved upon? Is this the end of the line?
