About to invest in room treatments; GIK, RealTraps, DIY -- what is your experience?


I'm reaching the point soon where I'll invest in some treatments for my two channel listening room. Standmount speakers with tube amps. Room about 28x14ft with low ceilings, 6.5ft. Probably different kinds of treatments are needed. I'm not exactly sure yet what I'll need or how much to spend. This is not my final listening room, but I won't be able to configure another one for a few years.

I've seen many people tout GIK on this forum and I'm already communicating with them a bit. I will also reach out to Real Traps and possibly others. I do not feel bound to go with just one company or solution, so if you've mixed and matched, I'm curious about that, too.

Any recent comparisons between these two, or others? Do you have stories of good or not so good products or service? Any comments about the value of competing products? I'm not super handy or have a lot of free time, but DIY is also considered.

Simply where sinx equals cosx on a sinusoidal wave between walls which is at 3/8 and 6/8 or 37.5% and 62.5%. No golden rule, just math rule.
Your objection is a tautology beside my observation and you dont even realize it....

The golden mean is precisely a ratio which relation can be inscribed in a SPIRAL and the relation between the cosx and sinx exhibit then precisely this 1.6 ratio then this rule 38 and 62 % whichi is only an empirical illustration of this universal fact in traditional architecture and acoustic.... 62//38 which is a gross approximation....55/30 and 89/49 are Fibonnacci number, 2 fractions on an infinite series convergent to 6.1803....38/62 being an approximation itself of 2 terms of these series....

You are definitely intelligent, way more less tough that you think you are...

You make me laugh, go on....

If you try to contradict me, try a real argument AGAINST, not in favor, of what i argue for and not repeating my observation under another wording....You trashed turntables lover with partial fact, you trash E-Mats customers with suppositions without any experience of their products for the pleasure to hurt them with no reason other than your stubbornness...No shame...


This ratio is the FACT......He was probably discovered by accident in room tuning with EARS or by someone who knows the importance in all field of this historical proportion in art and science....

No golden rule, just math rule.
Golden rule IS math....😁 Just this affirmation make you a recipient of the donkey prize!

Try this book written by a Russian mathematician ( the best on the subject ) :

There is no accident in using 38% (really 37.5% of 3/8th, or 6/8th). The room node lengths of any two walls is a complete waveform and multiples of that. 37.5% is simply where the originating waveform and its reflection cancel or reinforce each other out the least.


The golden ratio, unfortunately, is not purely math as you are no doubt aware. It is far too the proverbial square peg that people try to put into a round hole. In this case it is 1.67, and just happens to be close to 1.62.  If it was 1.7 or 1.55, people would still try to equate it to the so called golden ratio.

You see this what I consider sillyness applied to 16:9 aspect ratio for TV (movie) but this is again another false analogy. 16:9 was a technical trade-off. No more, no less. Our vision limit is 1.4:1 for black and white, about 2-2.2:1 for color discrimination (hence why widescreen movies are like this), and close to 1:1 for central vision.

There is no accident in using 38% (really 37.5% of 3/8th, or 6/8th).
The golden ratio IS not a human creation...It is a natural and mathematical fact ....

Then it is not an accident or an arbirary choice of a deluded man who want to peg it....


And seriously do you think that a general article pick on the net can ridiculized the work of a Russian mathematician (800 pages) I read it by the way....

This is my mathematician bio:

https://en.wikipedia.org/wiki/Alexey_Stakhov

Wrote to him about your facts correction in this not very informed "debunking" article.....

Stakhov is the best specialist on the mathematic of the golden ratio in the world , not a journalist....

😊

« Stakhov is a Ukrainian mathematician, inventor and engineer, who has made contributions to the theory of Fibonacci numbers and the "Golden Section" and their applications in computer science and measurement theory and technology. Doctor of Computer Science (1972), Professor (1974). Author of over 500 publications, 14 books and 65 international patents



You read too much internet articles and not enough serious books....

It was the reason why do dont even know what "timbre" is except a useless addition of colors according to tastes

My profession was counselling books to students and not only in litterature but in science also ..... By the way.... 😁


These are the last paragraph of this very impôrtant works:

«The eighth conclusion touches on the general role of the Mathematics of
Harmony
in the progress of contemporary mathematics. We affirm that the
Mathematics of Harmony can overcome a contemporary crisis in the devel�
opment of the 20th century mathematics what resulted in the severance of
the relationship between mathematics and theoretical natural sciences
[6].
The
Mathematics of Harmony is a true “Mathematics of Nature” incarnated in
many wonderful structures and phenomena of the Universe (
pine cones, pine�
apples, cacti, heads of sunflowers, quasi�crystals, fullerenes, genetic code, Uni�
verse evolution
and so on) and it can give birth to new scientific discoveries. »
Um Mahgister, no offense, but you do this in a lot of threads. Take a question and relatively focused discussion and drag it into your interesting but somewhat hard to follow and tangential directions. At great length.

Clearly you want or need to talk about these issues. That's fine. But may I politely suggest you start a thread with the things you want to discuss (however abstract they are) rather than injecting them into focused threads seeking to solve a problem? It would keep this thread open for more focused or useful contributions (to my question).
