Thanks a ton, @liverpool_for_life and @Enkay78 !
Tried running REW for the desktop speakers...
Of course, terrible results :D

But before that, it was an effort to even find levels.

All of which is patiently explained in the links you both gave.
I think theory first-try-outs later... :D

Thanks again

Room's coming along!
I like what the electrician has done with the piping...
But I really am left wondering what Monitor Audio means by that labelling! :D

How fragile are their speakers, or what has happened to them in the past in transit?! I don't have enough imagination to fathom. :)

Came across a hilarious poor quality clip (a White House recording circa 1964), which is a treat to listen to anyway for pretty much everyone:

Coming to the point, my experience was this:
1. Heard the above clip on a headphone and didn't miss a word.
2. Played it in the system, and there was so much lost! Not just in terms of audibility, but I swear, some words just disappeared. (Especially the funniest crotch-and-riding-a-wire-fence part.)

Which brings me to a couple of things @Decadent_Spectre and @liverpool_for_life told me at different points.
1. To a specific dialogue-audibility related question I had asked on this thread, Dec-Spec said 200-300 Hz could be the troublemaker.
2. Much later, after I experienced LfL's set up, we were chatting and I brought up dialogue intelligibility and how good it was in his room, he said addressing mid-bass was the solution.

Putting those two inputs together, am roughly putting a ball-park figure for HT users - addressing the 300 Hz-1K Hz range is far, far way more critical to a good experience than just focussing on how low the system goes.

My two cents from experience and acquired knowledge.
Would love to hear your thoughts.
Regards

More specifically, reducing decay times in the 300 Hz and below region. I have lamented previously about dialogue intelligibility issues and possible cause for the same. Well, I finally did something about it with the (now-installed) 5 bass traps. Dialogue intelligibility is now the best it has ever been in my room, although I still find myself asking what was said in some cases. If you heard everything crystal clear, then I have hearing issues. If not, we have different expectations :).

No, seriously. One of the reasons my interest in the Catalysts was piqued was the seemingly seamless combination of apparently limitless ability to retrieve detail and stay clear in terms of dialogue while doing so. It doesn't take much for stuff to be clear when there's little else happening on screen. It's how clear things are when everything's going to hell that can be revealing in terms of speaker quality, room acoustics, calibration and one's hearing.

This is the decay plot for my center channel (t=0 and t=160 ms), with and without the bass traps. As per one guideline, it is good to have the levels be attenuated by 20 dB at least within 160 ms. The test tone levels are not the same for the before and after and the frequency response is different as well (likely from moving the center channel up so the coaxes for LCR are aligned), but you can clearly see that the rate of decay (80 Hz and onwards) is much better with the bass traps installed and reasonably in-line (or better) with respect to the above guideline. And the difference is clearly audible.

It's a lot to do with the time domain, IME. Lower decay times in the mids and HF allow you to play your system louder so you can actually hear what's being said when the dialogue is quieter than normal. Lower decay times in the LF (hard to fix ringing here) and mid-bass (passive room treatments can clearly help here as shown above) allows for clarity.

Or, you can go straight to the comments of a well-regarded (now-retired from touring) calibrator in the US (Jeff Meier) and read his thoughts on the topic of dialogue intelligibility. A well optimized HT setup is no gimme. The best an enthusiast can do is read, learn and apply stuff that makes an audible/visual improvement to one's setup.

This was the reason I decided to upgrade from the LG soundbar I had. I was pretty happy in my small world when I used headphone once and was startled by what I was missing with the Soundbar. In fact I also contemplated living with the headphones since clarity and experience was so good. But, that would have allowed only one/two persons to watch at a time.
With the new setup I hope I would get the clarity I experienced during auditions.

Dear Good Sirs,
@amrutmhatre90, @liverpool_for_life, @Love4sound, @Enkay78, @aeroash

After weeks of procrastination, the UMIK-1 is finally on the mail and I am ready to REWk'n'roll :D

Would be much grateful for links to any beginner tutorials on how to get started with REW.
(Right now reading the two posted by ASR's Amir)

Regards
