What is the Silliest Accessory You Have Ever Seen.

@glupson, My group of people shunned the Soundcraftsman units at the time. We had already started to slide into the minimalist units without tone controls. Units like the Soundcraftsman were in part responsible for that movement as they seriously screwed up soundstaging/imaging. 
Now the Argent Room Lens. If one end of the pipe is open then they could function as Helmholtz resonators but I fail to understand why you would want something resonating by your speakers. As long as the pipes do not ring I suppose they could operate as diffusers at higher frequencies. They look like big door bells. They certainly have more potential to do something than the Hallographs which are too spindly to do anything. IMHO the best way to deal with room acoustics is to use directional speakers so that you do not bounce sound all over the place. Then a little absorption here and there is all you should need. In the small rooms we listen in you really want to decrease the amount of stray energy rather than redirect it. It is like clearing fog out of the way. Room treatments is another area where there is a fair amount of chicanery. Good contoured foam tiles are all you really need but unfortunately, they are not the look that some people want. You have to spend a lot more for decorator stuff that works. I am very lucky in that my wife does not mind them at all. I didn't even have to buy her flowers.

"I have never eaten an audio component even when it was new and made my system sound more alive."

You are not alone. However, my dog did. She ate new earphone cord.

... others don't have to do "experiments" to know how something will or will not work ...

Yup, that's the definition of the measurementalist. Real scientists conduct experiments to help evaluate empirical evidence.

"Real scientists conduct experiments to help evaluate empirical evidence"

That may be a bit of a stretch in some areas of science. In many of them, experiments are done to evaluate hypothesis which may, or may not, be based on empirical evidence.

As it is these days, in the end something does get measured in most, if not all, experiments conducted.

I try to control the sound in my room with mostly vented anngular devices on the ceiling and on the floor to capture and redirect energy at or near my listening position.
Some of these are permanently mounted some are portable. In either situation they are all direct coupled to the floor or the ceiling.
No springs damper gliders no sliders..I want to keep all the energy and control its direction.

I see these angles I installed 25 yrs ago in a much better light now that I have moved ahead with an active laminar flow device that also actively treats the air..I have been doing that all along for 25 years with the passive devices I installed back then including the Argent Room Lenses. The active device now gives me more control and improved focus over the entire listening area..The only combing of the air devices I use are at the first reflection points and 3 along the 21ft wall behind the equipment and the speakers. The panels I constructed have have long hair sheeps wool suspended and covered with fabric. Foam and fiberglass sound as if I am wearing a hoodie or a toboggan. This is how I operate. Tom
