Please read with google translate.
정재파와 플러터 에코 자기만의 리스닝 룸을 갖는다는 것, 오디오 애호가들의 로망이다. 자유로운 기기 세팅과 최적 볼륨 확보를 통해 오디오 기기가 내줄 수 있는 최선의 음을 듣고 싶은 까닭이다. 하지만 리스닝 룸의 숙명 같은 것이 있으니 바로 정재파(Standing Wave)와 플러터 에코(Flutter Echo)다. 말은 어렵지만 이는 누구나 알고 있는 ‘방이 내는 불편한 소리’다. 속이 메스꺼워지는 부밍, 귀가 아픈 고역의 비명, 특정 악기 대역의 실종, 이런 것.

Google translate did an excellent job with both articles, It was a very easy and interesting read, and it cleared many doubts for me. I found the following paragraphs very useful:
"Nihon Onkyo Engineering (NOE), Japanese sound engineering in Korean, was established in 1972."
"These products appear to be lined with simple wooden cylinders, but there are differences in the material and thickness of each tree, assembling method, and even paint or painting method. Of course,
this is the result of numerous computer simulations, and if any one of them is changed, the AGS effect is said to be significantly reduced."
"AGS technology won the 19th Technical Development Prize from The Acoustical Soiciety of Japan in 2011."
"NOE explains that AGS units can 1)
suppress standing waves of low frequency, 2) alleviate the adverse effects of reflected sound, and 3) achieve sound-absorbing effects depending on the installation location."
From what I've seen, FL1 has to be used like in the pictures, just sitting in the floor and not on top of rugs. A rug can be used in the room but not below FL1.
Is good to know that the company is not just an "overnight success", but has almost 5 decades of experience and the products have some serious R&D behind them.
Thanks for sharing the articles!
