My pick KEF R11;
Why :
Almost flat frequency. - let’s hear the recording without adding or removing much
Excellent directivity - directivity is mostly forward so, less affected from sidewalls like traditional speakers. Placement isn’t going to be a big issue in the room in terms of the sidewall reflection.
Excellent low frequency extension-can work without a sub
Low distortion- now this is where it gets really interesting. If you look at this graph below. This is how we calculate distortion in percentage

We can hear distotion in a different way for different frequencies. But anything with these numbers are close to inaudible. What does that mean, I can push up the loudness levels of several bands here without distortion reaching audble levels. So this speaker can be eqed to literally any other speaker and still will not add distortion doing so.

The soundstage of this speaker is limited to the directivity to the front. So if you remove the shadow flare may be it would work sideways(I won’t do it)
This also means if I play a 40 hz tone, it vibrates equivalent to its time domain equivalent in terms of strokes and low distotion suggests there is no “overhang or swinging” by the drivers meaning in audiophile terms- excellent timing.
4. Coaxial with no problems exhibited by traditional coaxial. It’s very hard to get a coaxial right. Problem is you have a midrange that would vibrate which is the wave guide for the tweeter.
Kef managed to fix this problem with the tangerine waveguide and the ribs on the cone to direct it without any flaws.
Also coaxial means the best possible coherence between mid and the tweeter for accurate soundstage representation. Cymbals won’t sound above or below the vocals if recording doesn’t have it.
To me, there is nothing better than this you can buy under 5 lakhs may be even in 10 lakhs.
The stock sound has some flaws (minor) but with little bit eq it’s tunable to perfection.
Low impedance change with frequency - means it has lower amount of sound change with amp impedance change
High sensitivity- low number of parts in crossover (it’s laughable!) sensibility is high due to less power wastage.
Driver engineering has taken huge steps further hear as I won’t be surprised to see even less parts in the next gen.
... very much deeply , so much so, that I fear to open the next video
