KEF LS60 with a pair of KC62s v Blade 2

Height of subs shouldn't matter as much as the ls50's and even those can be tilted a few degrees if necessary. Measurements show the uniq driver is linear to +30deg so toe in shouldn't be necessary yet some reviewers still claim improvements from pointing the speakers directly at the listening chair.

I just listened to all the Kef’s mentioned here. The LS50 Wii sounded ok before you turned up the volume then things got really distorted, even with the different settings on the kc62 sub. Maybe a higher crossover point would have taken some of the burden away from the midrange.

Blade 2 was pretty good. For $28k, I would go with other brands for the same price or cheaper. 
 

The ls60’s are baby blades, The midrange is quite a bit smaller than the ls50 Wii but the ls60 had so much better definition, no breakup when turned up louder. For $7k, they are a good deal for the sound quality you get. 

The uniq in the Blade and Blade 2 have a 3" voice coil and multiple other considerations intended for hi power handling and high output with low distortion  unique to any of the other models before or since. Like most speakers in their price range they respond to components driving them so could sound amazing or just average(for the money) depending on the individual component matching. 

On a budget the ls60 is the safe bet but the ceiling can't compete with what the blade's can do when a systems built around them.
