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

Give me a pair of "The Apogee" or the mighty Infinity IRS V, that's what I consider to be in the worlds greatest speaker collection.

8"x48"x16"   and 112 pounds  

At least to me the images I have seen can be misinterpreted as a much larger speaker. Another strike against it being best in world- it's smallish. You don't even begin to be in "best in world" class unless you can reach  about 5.5-6 foot (2M), imo. Scale is so much more important than people want to believe. 

I'm sure it sounds wonderful, stunning, etc. But, I have heard many wonderful, stunning speakers that aren't best in world category. Then again, it's not priced as though it has pretense to be best in world, which is strongly in its favor. It may be priced appropriately to performance. I would guess it to be a lovely listen.  :)

Plus one for scale.        When I hear complaints about systems being unable to deliver the dynamics and size of a live orchestra, I guess they’ve never heard any of the IRS Series (even the Beta), with (say) a pair of VTL 300s.               Perhaps some big Wilsons, or- Avantgarde Trios, with some stacked Basshorns.      In the right room, of course.                                 Yeah: scale!

The Dutch & Dutch 8c uses a proper waveguide, which looks to me like it’s based on Earl Geddes’ Oblate Spheroid math, but evolved to meet the specific requirements of a dome tweeter and on-axis listening. (The original Oblate Spheroid measures and sounds best from a little bit off-axis, so it’s not an ideal studio monitor solution.)

The Kii 3 uses a different technology, one which is better than most, and which may do some things better than the Dutch & Dutch. For instance its high frequency dispersion is probably wider, which may be desirable.

Based on experience with the horn technology Kii uses, and with the horn technology that I believe the Dutch & Dutch has evolved from, I agree with twoleftears. But I think the Kii is still an absolutely brilliant design.
