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

Try my last experiment... Cost: nothing...
Reward: a totally new system....

"Helmholtz-Fibonacci silent organ" A room tuner i devised myself with bricks and plumber pipes in one hour...If you have crafty hands you can make them esthetically beautiful.....

They work with a group of three bricks of three pipes inserted in three holes in each of the 3 bricks; 9 pipes all in all, which have each three set a lenght approximating the golden ratio, then changing the way sound waves react to the normal pressure of the room...

Helmholtz is the father of room correction and the golden ratio optimize the working of the resonators on all frequencies....You must choose the lenght of the first 2 sets not too distant from one another and the last set must be with more distance in lenght compared to the first 2....i located 2 sets laterally to each one of the speakers at some short distance and the bigger set behind my listening position... 😉

Experiment with your room it is fun.....

I sell creativity not products....No cost....

Audio cost nothing if we know what we are doing, and if  we dont know, it cost also nothing  we experiment,  we learn how to do it....

 Dont fall for the upgrading obsession...


Acoustic is the main working dimension of audio system, their electronical design cannot beat a bad room....
In a very good room only very, very bad system sound bad.....

I'm not against the idea of a Helmholtz resonator type of solution, but I'm not yet sure which frequencies are most problematic. I do not have too many peaks, the greater problem is with nulls. 

My Helmholtz-Fibonacci resonators are not ordinary Helmholtz resonators... I use many ordinary one i created myself but this one is more powerful....

The most important factor is the ratio 1.618...between pipes



The series of proportionate lenght between this "silent organ" like set of pipes cleaned most frequencies ....It takes me one hour to make them with some 3 bricks in my basement and unused copper regular plumber pipes of 1 centimeter1/2 diameter....

They act marvellously at one condition: the ratio must be respected to not impair the balance between interacting frequencies...

Only one or 2 inches, too much or too less, on only one pipe, will produce a not well balance sound very audible...Approximate measure around 1 centimeter will do no audible harm tough ...

My idea come from the best Book ever about the mathematics of the golden ratio....Then i coupled the ratio idea with Helmholtz idea....The golden ratio, like pi or the number e pilot the universe at all scale....

By the way the key to Greek acoustic and Egyptian acoustic is this ratio...I read a book about that 45 years ago....I remember the price of the book : 125 dollars in 1977.... A very great book i never regret it....In french or in english it is sold today at the same price than 45 years ago, a real bargain today in relation to inflation....😁 It was an analysis of the Karnak temple in 2 volumes in Egypt by Schwaller de Lubicz..." The temple of Man"...

But these 2 books are 1000 pages each almost and not easy reading.... 😁

One thought as well, before investing anything, spend $100 on a measurement microphone and learn how to use REW or something similar.  We are not talking cables here where the difference if at all is debatable. Acoustics can provide measurable improvements and a good place to start is knowing where you are starting from.

I have ASC, GIK, Michael Greene, and acoustic field products in my room. I have anywhere from sub-bass absorbers to diffusers. Both GIK and acoustic field offer diy products and videos to build your pieces. I bought the 8 dvd set from acoustic fields to build pieces. Any of the above mentioned companies will work with you on what you need to treat your room. Also, I think argent is no longer in business.
