If Audiophiles care about sound, then why so few threads on acoustics

Identical frequency response can sound completely different if one isn’t paying attention to noise. The biggest gremlin in modern times is plugging direct to a router. And no Cat 7 cables are trash and merely add more noise in. I’ve heard this personally, it can take a system from tons of bass to 0 bass despite the fact an RTA says bass is there. 
Two speakers can sound completely different in the same space. Goldenear vs Zu for instance don’t sound remotely the same even in the near field even. 
Some speakers need ideal conditions while some are so musical, room treatments don’t matter as much.

I see the romance blooming.

Frequency response doesn’t matter as much as timing and phase.
Take any room and play an acoustic guitar... it always sounds like an acoustic guitar.
Why is the market so obsessed with speaker design which butchers the time/phase domain? So when you combine the jacked up timing domain with poor driver / amplifier control due to the crossovers... instruments never sound real. This is because you split the harmonics between drivers which have different timing behavior... this is a major reason nothing sounds real no matter what you do.
I want music to sound live.... room treatments do not alter or change whether the sound coming out of speakers sounds live or not.
Now combine a great speaker that is highly musical with some diffusion panels and proper placement... now we’re talking. Take some traditional 3 ways... I don’t care what you do, you’re always listening to speakers.... not music.

That is totally untrue. Speakers shouldn't be musical, and I have never heard a speaker that would not be better with room treatments .. much much better.

See your statement above. Unless you are sitting nearfield, there can be more energy in reflections than directed.... guess what reflected energy does to timing?

It's a common  misconception that low damping factory, i.e. driver connected directly to the amplifier always results in lower distortion. Often it is worse.

Well one big reason is because many folks have their systems in shared living spaces like the living room. Many spouses do not want all manner of panels on the walls etc...no matter how attractive some of us think they are. The spousal veto vote on these panels and such is real and impacts many Aphiles.
