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?
I was contemplating the same issue. I even asked KEF USA about the next version of the Blades and they said nothing was in the works. I was thinking that KEF may change the driver material but they have 11 iterations of the same driver now (not sure if it was always the same material).
I think that this may indicate that it's getting harder to improve on the current state of the art in sealed box, cone driver speakers. I'm not sure how much better you can get than the Blade or the Solon 2.
