Did Amir Change Your Mind About Anything?

You cannot have a clue about Helmholtz resonators because you did not even mention them for the bass problem in a room... You mock those who use material treatment favoring EQ alone... It is ignorance...

By the way what you speak about the specialized use of ONE resonator for the bass control for a precise use in a room  is something already commercialized with success , it had no relation with a distributed grid of one hundred resonators,  from 8 feet high to small one,  and their effect on the pressure zone distribution and their effect on the relation between the speakers and the listener when tuned and located appropriately..

... You cannot learn that ABSTRACTLY you did it or not... with your ears...

I had no results my friend, i had an acoustic room better or not too far from what i look as your room at no cost... but hard work...😊

how i know ?

a soundfield filling the room able to gave to each recording a complete faithful translation..

Why it is faithful ?

because each recording in an ideal audio system must be DIFFERENT... Each one...

What is more valuable than buying the book is experimenting with it by the way ...

By the way you suffer from Alzheimer...

i already said multiple times i have the Toole book.., then when you speak to me speak to me not to an invisible crowd...

stay healthy...

I learned acoustic by studying but experimenting at the same time... I don’t know what you have learned. I can only go by what you can demonstrate here and so far, I have not seen you express anything in this thread indicating any knowledge of the field. Maybe you know it, but I don’t know that you do. You cannot change the fact...by mocking all people here and thinking you are alone with books and articles... and only you can read them... A claim of knowledge is not a fact. Nor have I mucked anyone individually. I discuss the technical point and show measurements, references, and other data to prove them. You have something like that, let’s see it. Start by demonstrating how you know the perceptual effects of lateral reflections. As to the book, it costs so little compared to what people spend on gear/content. I suggest you go and buy it and read that, instead of wasting time here. And yes, that includes reading my posts. The book is that valuable.

In my living room the two easiest acoustic tweaks I made were to experiment with the angles of the wooden louver blinds that covered big glass windows. There was a certain angle that broke up chaotic reflections but did not deaden the room. The other effective tweak was to distribute small throw rugs over the wood floors between my speakers and the listening chair. This was not a total blanketing of the floor. There is a mix of throw rugs and unobstructed floor. A little creative orientation of the rugs brought an obvious improvement to the sound. To allege that this treatment is ridiculous is well...ridiculous.

You did the right thing, experimenting and you learned...

i did as you...

A bit more foolish though... 😊

Most people who focus on gear or on toy, negliging acoustic dont know anything...

No, it is impolite and screwed up logic on your part.  This is not a thread on acoustics.  I am not at all attempting to engage in any kind of full blown discussion on such a complex topic in this thread.  You asked me what they were, and I instantly gave you an answer and the cons of the solution.  That you don't accept that -- without facts -- means nothing.  A day in the park in an audio forum where folks claim all kinds of expertise.  Come with data, not just indefinite word salads and personal commentary.
