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

I hate to judge so harshly but some people oft say the first thing that pops into their head. 

You’re not ready for stand up. I have noticed your inferiority complex however.

Wonderful methodology discussed here for those who wish to maximize mediocre performance of an audio system. It won’t approach upper end performance, but one can always pretend they have obtained it.

>>>>Yeah sure, pal.

Room acoustics can be a fairly complex subject... and imo if we’re talking about home audio, the speaker’s radiation characteristics and setup also come into play - in other words, it’s not just about the room.

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

The first part of that statement I agree with: Typically there is considerably more energy in the reflections than in the direct sound.

>>>>The sound pressure peaks in room corners and other oft unpredictable locations in the room - including the 3D space of the room - interfere with the primary signals from the speakers. How much do they interfere you might ask. Well, at normal listening volume the sound pressure peaks in room corners can be as much as 6-9dB above the average SPL in the room. That’s 2 to 3 times the average loudness! The comb filter effect of multiple sources of sound pressure in the room kill any chance you have of receiving a pure signal at the listening position. To make things more confusing the peaks might not be exactly in the room corner, it might be a foot or two from the corner. That’s why a SPL meter is valuable. Tube traps are sometimes put in the wrong place for that reason.

There is only one geoffkait. And he’s got your number. 

Actual experts? Not audiophiles? I hope you don’t mean Ethan? Hey, that rhymes! 🤗

Whatever you decide to get for room treatment first get a hold of a SPL meter and the test track (s) of your choice. I happen to like 315 Hz, maybe you prefer other frequencies, who knows? Without some way to measure the results of room treatment - just like speaker placement - you’re shooting blanks in the dark. Trying to treat the room by listening a little and moving a little is a lot like trying to solve x simultaneous equations in x + n unknowns. Rome wasn’t built in a day. After you establish where all the tube traps, diffusers, tiny little bowl resonators, etc. go, one at a time, then you need to reestablish speaker locations again.

There are probably 100 products for treating the room. Half of them I’d opine don’t operate on acoustic waves. I sell a bunch of “room treatment” devices myself, most do not (Rpt not) operate on the acoustic waves. But they’re still “room treatments.” Even the tiny little bowl resonators do not operate entirely on acoustic waves In the room. Surprised? 🤗 Confucius say keep open mind but not so open brain fall out.
