You need SPL and good mid-highs because that´s where the Guitars are.
Range/distortion/quality?
PA speaker specs are fine, since if you attend live Rock venues that is what you´ll hear anyway, so that defines the playing field.
But ... but ... what about Studio recordings?
Oh, they are nice, but: no Rock Recording ever compares to the real thing: head crushing chest thumping LIVE performance, so at least try to get as close as possible.
Old nosy neighbours?
Hey, what are you doing there? 😕 🙄

Some of the very best rock albums were pure studio recordings tho. and if you listened to the Rolling Stones they were mixed [ it seems] for listening too via 3inch drivers in transistor radios and never got any better [ OK Maybe Goats Head Soup had decent levels and clarity] so I'll stick with the metal dome D25AG for this set.
Has anybody ever used the factory recommended XO for this tweeter?
Seems a bit out of whack to me? A 3k XO using 12uF inline and 0.22mH shunted to ground? Yet it is OK with a single 6.8 CrossCap ?

Rock is kinda broad really. I consider Floyd, Rush, Yes all to be rock and wouldn’t hesitate to enjoy them with a nice 1” soft dome.
Weird, I just calculated the reactance of the Vifa XO and got 1893Hz so what would people recommend I should use at 3k as an approximate starting point if the Vifa XO is so wrong??
In several past builds I have successfully used the Vifa recommended values as a starting point

Old data sheet I know but it is the one that came with the tweeters

FWIW, the test was at 2000 Hz/2nd order/85 dB/m IIRC [I forget which 6.5" woofer] and the particular pair I auditioned were surprisingly smooth compared to the Ti, though not 'soft' sounding like its textile variant [lacking in 'inner' detail].
In short, its tone was similar to the Altec 802 when set up for super tweeter duty [my reference], so made a note in case I ever had a need for some, thinking at the time that it's too good not to keep in production, so was surprised to see it long gone. Then again, maybe I heard a better than average set.
Regardless, a general rule is to add an octave per order, so if an 850 Hz Fs, then at least a 3400 Hz/2nd order, but for whatever reason they traditionally are at even or half numbers, so this would be either 3000 or 3500 Hz and Vifa chose 3000 Hz, probably based on power handling.
Half power then would be 1700 Hz/2nd order in theory, but they list 1st order, which would shift it back up to 3400 Hz [ref. 6800 Hz/1st], yet lowered it to 2000 Hz!, so a screw up? Otherwise no clue what I'm missing, but would be careful testing its viability.

Document stuff-up.
Most of the references to this tweeters use seem to hover around 3k to 3.5k and I think this is the most copied XO for quick and dirty
Vifa 2-Way Loudspeaker System
I'd be looking at the FaitalPro 6" for this speaker if they were not so expensive here eve tho it started as just another garage speaker

Cool! Totally forgotten about his DIY projects and Audio Lab of Ga. that's now within walking distance! Thought they closed decades ago when the shopping plaza ~5 mi. up the road was leveled.
Gotta love a world community where someone on the flip side half a world away can point me to a 'lost' shop ~around the corner from me! Thanks!

Your Peerless looks like it can handle a 1st order, so to start with, try just a cap at > 13600 Hz HF, 3400 Hz/2nd on woofer or points around these. Just remember that HF Fs needs to be at least -24 dB.

No problem 😀
