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.

It’s very hard to know where the standard 38% position is, given the irregular shape.
This location is indeed very good....

this is the golden ratio....

My 2 locations are good and the 2 are at this same ratio, one from my front wall (near listening) the other regular position from the rear wall at the same ratio...My room is irregular but permit this....

Try to discover a location in your room inplying this ratio....

1.618 is the magic number of nature....

62 divide by 38 : 1.63

My Helmholtz-Fibonacci silent pipes organ, a room tuner has all  three sets of three pipes cut with this ratio....

😊
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.
