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

sharbatgula, you point out one of the outcomes of multiple smaller bass drivers; the speaker cannot - and I do mean "cannot" - sound as effortless as one with, say, multiple 15" drivers. The "tension" is due to the use of smallish bass drivers versus drivers that will with ease produce the LF. 

As regards your saying they are not the most transparent, there are many factors involved in the system's transparency, so I would have to listen to the speakers in perhaps up to 6-10 systems to know their limits in that regard. No one is able to know a speaker's absolute traits from one or two systems.

There are so many great speakers out there, is there one that is sooo much better than another?  It really comes down to the ear of the person listening, the amp driving them. The source feeding it and so on 

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.
