Not with the OP budget :(
Just an example around 700-900$ (and if someone would make an offer, usually you could get a lower price):

I understand that state of the art drivers don't automatically make a good speaker, but i like to see companies asking for big bucks using them.
In that regard, i find these speakers very interesting:

I've made a resume on the various types of materials for acoustic panels here:

We can sort of compare the two with objective data :)
Databass measured the old (2016) JTR S2, as well as a DIY version (sealed dual opposed B&C IPAL 21) of the PSA S42 IPAL.
The new JTR RS2 should be a step up from the old S2, and on the RS2 page its mentioned that the new 18" woofers are...
As others mentioned, JTR 100%.
If you have money to spend at around Perlisten values, i would look at harbottleaudio, for example this 24" offer :)

Another option, which won't go as deep as the JTR or the harbottleaudio, but should be amazing...
My ECM8000 was almost as accurate as my CSL Umik-1.
I measured both (tried to set them in the same exact position as much as i could), and they measured very similar:
There is now a web version of ratbuddyssey:

Why not just get a Denon X3800H and buy a Dirac DLBC license?
The Denon can work as a processor, it has an option to disconnect the amps.
With the use of DLBC, it will beat all other processors you mentioned!
