Threads topics sometimes wander.
It's been the case as long as I've been on the internet.
Delusions?
Recently i blindly joined a Facebook group, posts unseen, to ask an audio question regarding "tuning" a room which uses two box subs in stereo, with two left over dipole bass W Frames, hooked out of phase, with separate crossover, amplifier, upper rolloff, and volume control.
Once accepted, I Marvel at all the posters answering almost any questions with various wire and cable brands for speakers and components. Did I miss something? Are all interconnects and speaker wires now fitted with some version of Harrison Laboratories FMODS? Personal note, I am still in disbelief many believe a component can be fixed by changing parts or all of a cable loom.
By the way, it's not one group only. Glad I can see; many have said I'm deaf if I can't hear the dramatic improvements.
Post script- recently a long time friend gave me his biwire MIT Magnum speaker cables and three matching interconnects. Apparently the system I've assembled and improved for 25 years isn't resolving enough to reveal the dramatic improvement over my old semi fancy interconnects. SMH.

some think you can fix ANY problem w/either interconnects or upscale speaker cables.
I wish I could help you w/the room. If you were closer... “tuning a room” is neither difficult nor expensive. I like tweaking systems - the room is a good place to start.

My next door neighbor buys into that "fancy wires" crap too.
His upscale system is on a simple (but expensive) rack, speakers are right next to it.
Gotta love it when it's cranked - shedding feedback from the Acoustic Research LST's into the Dual 701.
He reads too much from audio fools.

I upgraded my speaker wires that were lamp cords, to thick wires looking great with their transparent insulation.
I listened carefully to one of my favorites. "Oh Lord don't let them drop that atomic bomb on me".
You won't beleive me, I noticed no difference.
No placebo effect, nothing.
Amazing.

Me too
A friend of mine gave me his biwire MIT Magnum speaker cables, and three matching interconnects, and later a PS Audio Powerplant Premier. After all was hooked up, I heard... My system. Still sounds the same to me. It does look nice though, and it has a voltage regulator feature, which seems to work well, according to the display on it.
Marketing done right can achieve some amazing results... Conversely, no marketing, no substantial financial reward.
You have to get a potential customer to believe buying your product is absolutely the best thing they can do with their money. Particularly if that is not so in fact.
Some products are. I always liked Motown's edict - that the product has to be so good, if you had just 1$ and the choice between eating and buying the record - you'd have to buy the record.
I'd eat first, then worry about speaker cables.

Joe's got a sensible outlook, yes.
The general public is of various knowledge when it comes to most things, most products.
The marketers depend on less technically educated to hawk their wares.
For instance, the common, beer-drinking guy has no idea about speaker wires, or any wires.
At best, he may know that Romex house wiring in higher gauges can carry more current safely.
But speaker wires?..... interconnect (rca-hdmi-rg59, etc.) wires?
Nah..... he'd normally buy some inexpensive Kmart or BestBuy stuff....or whatever his local hardware store has in stock.
Mchambin said it well.... he couldn't hear a damn difference with fancy cables.
And rightly so.... copper wire is copper wire, and all those types that "bought into" the marketing crapola about types of wire can enjoy their "perceived" improvements in their systems.
When a 10 foot length of "standard"16 gauge zip cord which amounts to 0.045 ohms can make a speaker sound lousy, I'd love to know how that can possibly be. 🙄

Just a general query after looking at many groups or forums. For open baffle, with a full range driver for simplicity's sake. Many have said a disc or rectangle may be the worst shapes for open baffle, and post sims demonstrating that similar edge diffraction will sum the common distances, and result in inferior playback. They all show the sims, and a driver centred in each baffle to prove the point.
I've casually made and built one off design speakers for decades, many types. I don't use measurements and always fine tune by ear, and test tones. It is more work for me at least, to match a crossover to an asymmetric layout of drivers on any surface.
Am I missing something here? Even on a disc, wouldn't the centre of a full range driver , off centre by even 11% or so mounted on an open baffle, have infinitely varying distances to the baffle edge, and avoid summing common distance edge diffraction?
If this bores you, please don't respond. Ever since finding fractals and uncertainty, I've been big on asymmetry. Some of my open baffles even have different lengths on the two folded "wings", even the angles change, although I like the looks of 90°. Me perforating the small wing near the tweeter with multiple 1" and 1.5" fully radiuses holes draws a lot of chuckles too. They're always left alone after supplying a flat construction paper piece big enough to cover the holes, and a bit of blue putty to temporarily fasten it.
That's outside the box! Lol.
Cheers everyone, thanks for all the great posts and opinions expressed here. I couldn't really find one area to ask this, and am frankly underwhelmed with promising seeming Facebook groups.

If the smoothness of an axial response plot were the only thing that mattered.
Of course diffraction is difficult to identify by ear, not so easy to measure, and it's difficult to quantify with regards to audibility in its various forms (without going out of your way to research it). To be honest my own initial guesses on the subject were quite useless and I see similar repeated again and again.

things that make me laugh
Over the decades (anyone remember, eg., Rec.Audio.High-End discussions... the late Arnie Kreuger's ABX switch efforts, for cables & other things)... or the Amazing Randi's $1,000,000 cable challenge?
those were the days, eh?

Same boat as me, but I refuse to use lamp cord simply because it isn't cosmetically pleasing to me.
I refuse to use cheapo interconnects though- spent too much time trying to track down bizarre issues that amounted to either poor shielding or (more commonly) a crusty connector. Mogami / Canare microphone cable isn't too expensive and is of great quality.
That beer drinker would have the Romex backwards, lower gauges carry more current safely, don't use 18AWG to hook up your stove.
You must like it hot, 0.045 ohms for ten feet would be at 122F, 50C!
And a 10 foot 16AWG speaker cord would include 20 feet of resistance, about .08 ohms at 77F, 25C.
OK, my work here is done, time for a beer...
I had an "electrician" that thought the breaker rating determined the current carrying capacity of a circuit.
