Are the KEF Blade/Blade 2 Metas a Significant Upgrade from Blade?

What I notice when we get to the $25k speakers is how smooth the mids and treble are. Good, affordable speakers will squawk or chirp with hard recordings and the early uniq speakers could be ruthless. The Blade uniq is already as smooth as any out there and is unique to the model. Comparing the ls50 to the ls50 meta isn't indicative to the blade to blade meta as the blade uniq was already addressing the backwave to a level none of the other non meta speakers did. 

blade uniq was already addressing the backwave to a level none of the other non meta speakers did.

Can you reference more info on this statement. My understanding is that the old Blade uniQ is slightly compromised in relation to the uniQ in the old Reference line so as to fit the enclosure.

Audiotroy also posted some info about the Blade driver having some upgraded part compared to the LS50 non-Meta  but nothing related to back wave elimination.

Most companies that address the back wave use something elaborate such as the tube in the Yamaha NS5000, the tapered tubes in the Vivid lineup. I believe the Meta is Kef’s first real push into this area.

A comparison of KEF LS60 and pair of KC62s with Blade 2 Meta would be interesting. Wonder how close you get with an MSRP of $10K ($7K for LS60, $3K for KC62s). I’m using a pair of KC62s with LS50 Wireless II in my living room.  The SW controlled DSP KEF provides for the wireless speakers does an excellent job of integrating the speakers with the subs.

The uniq driver in the blades uses a vented magnet, I believe it’s the 10th gen uniq with the custom tweeter. Each line of kefs use a different uniq with the blade and blade 2 being unique to even the reference, now the ref and blade meta use the same uniq driver, while the R uses another unit and the q line different still.

KEF’s vented tweeters were suppose to address the same issue as Meta, back wave management; I guess not quite as effectively. A friend asked me whether he should purchase a Ref 3 Meta or used Blade 2. I told him he should try to listen to both but I’d favor an excellent condition used Blade 2.
