Are these Speakers the BEST on Planet Earth ?...

Seems to be designed to act like a dipole that yearns to be an omni....*G*

It'll still come down to the space it occupies, placement, the driving equipment.....the same parameters as faced by any other speaker pair.

Reminds me of the Devailet speakers in some ways, but certainly in a more 'conventional' appearance form....

Best speakers in my opinion were probably B&W Nautilus speakers.  Up at the top however, most are very close to each other.

I don’t like them for two reasons.
1) The speakers have DSP. I don’t like my music messed with by DSP in speakers.
2) I don’t like passive bass radiators at all. These speakers have two on each side of the speaker. 
  And since it seems they went out of business, oh well. 

I agree, the B&W crazy expensive Nautilus speakers look like there from Aliens movie, but awesome except I don’t know if they use diamond tweeters now, or the old aluminum ones still. Haven’t seen them in a long time! Saw them in the 80’s. Stupid heavy too! Would need a BIG room for those suckers!! A REALLY big room!! Part snail cone, part Aliens movie.

I heard the original, snail construction Nautilus driven by multiple Krell stacks and a custom outboard crossover at the B&W distributor in Mass.

I can’t tell you all how bored and disappointed I was with the sound that came out of them.

Honestly, the Matrix B&W before and Nautilus derived speakers after sounds much more fun and more interesting and transparent to me than the flagship Nautilus, which I have to admit to me was gorgeous as sculpture.
