That's your definition, most call that smooth/continuously decreasing, linear response usually means flat.
Nope, there exist constant directivity designs which result also to a relatively flat room response. Such don't sound as bright as when someone equalises a loudspeaker with increasing directvity like the KH120 to such as for the first the direct sound is flat while for the second it will be increasing to high frequencies.
They have an EQ setting for a near wall placement.
I do apologise then, as I was incorrectly inferring from your report of the Reddit issue that you’d actually heard some. Thanks for explaining.
That may be because KEF is based in Britain. We invariably have modest living rooms, often shared with the rest of the family. US homes that I’ve visited and stayed in often have vast spaces, open plan areas, dens and listening rooms unheard of by most in Blighty!
Smoothnes means that the function of amplitude for each frequency behaves non-abruptly, within some degree of finesse of the sample (in a very sensitivity analysis all speaker are non smooth).
From what I understand the idea of a monitoring and driver movement correction system is not new but it is quite a challenge to pack the sensor and the power for that sensor into the driver motor system. with VECO they printed the coil lines on a flexible foil which replaces the former on the voice coil and acts as the sensor which is based on inductance, so requires no external power. However the coil on the foil would couple with the magnetic field of the voice coil but thanks to a special winding pattern of the coil lines on the foil they avoided the coupling and thats the key innovation of veco. So to answer your question: yes they mitigated the downsides of such a system.
Yes, but for frequency response in audio usually no one calls a linearly decreasing or increasing (which btw is usually only linearly at logarithmic scale) as a linear, an audio device with a linear response means usually flat.
I think you're confounding on axis flat anechoic response with linearity, but if you want we can continue the discussion on personal thread, to don't deviate off this thread topic.
“ In addition, the internal volume of the LS LUXE cabinet is approximately 50% larger than the LS50.” From the KEF white paper, so presumably the internals are quite different?
Maybe the extra room is for improving low response distortion-group delay, port resonances...
The speaker is a bit bigger. But They used a different cabinet material which made it more inert by default. The shape might help with resonances too but not sure about that. This allowed them to reduce the internal bracing which freed the internal volume. More volume will help with efficiency, not sure about other benefits.

What you describe is than either linear increasing or decreasing, not just linear. However you and @thewas can both be right at the same time, since something can be right in a mathematical dimension and still have a different meaning in other context through conventions agreed on by society.
I think you're confounding linearity of a LTI system with a linear frequency response but as you said this is now off-topic and can be discussed if interested in a PM or in other threads like this https://www.audiosciencereview.com/forum/index.php?threads/the-meaning-of-linear.43373/
Quite interesting, one of the technical experts use engineering definition of linearity, stating that not means flat response, but he adds that the term has evolved in audio to other meanings.
Did you see that guy making some "fan-base" DIY grilles for LS50?
I'm really drawn to these "money-no-object" bookshelves.
