Most rooms don’t need acoustical treatment.

mahgister your Helmholtz devices, you are using them for bass EQ primarily? or ALL frequencies,

Helmholtz devices rightfully understood and designed works on ALL frequencies...

Yes we can use them for bass tightening purpose, but teaching that this is their main purpose like in some acoustical marketting advice is erroneous...They are a room tuner not only a potential bass device....

My Helmholtz tubes and pipes, distributed in series, i chose set of three with a ratio 1,6 between each three pipes with a straw of variable lenght determined by listenings experiments work on ALL frequencies scale directly or indirectly... i called that a " silent organ"....Someone more crafty than me like you are could make them beautiful by the way.... I use ordinary straw but someone could use anything less cheap and more esthetic...I use old plumber copper pipes or PVC tubes with a sheet of plastic for cover....It is homemade to say the least...But nevermind it work powerfully.... My goal was not esthetical anyway but Hi- Fi experience for the poor... 😁😊

I have 18 tubes and pipes  with tube one 8 feet high.... My main set is 2 sets of three....Cutting only 1/2 inch or adding 1/2 inch from 6 straws will change the sound of your room MORE than changing an amplifier or on par with changing bad speakers set for a good one or the opposite...I guess someone could do a good job with 3 set of three  the longer tube around 8 feet and the shorter one of the nine pipes for example around 6 inch  with the ratio 1,6 between them ....

Only one straw can destruct the room acoustic or transform it like the tightening of a string on a violin....

Acoustic is an empirical science and art because nothing could replace ears.... This summer i will use a mic. to optimize the speakers/room response tough... But advising peeople to use equalization to replace room acoustic is pure ignorance....Equalization work only for a precise test frequency in relation with a very precise spot it is a complementary tool not the main tool for tuning the room to MY ears and his particular structural properties... Nobody want to listen to a "perfect" sound but to the sound which will be pleasing for his ears specific abilities ....I apologize for my digression from your question.... I have many defects and i speak too much.... 😊

My best to you and best wishes for your health.....

Thanks, really got me thinkin’, look out.. LOL

Always wanted to be on a build team of a HUGE pipe organ, I’ve seen 3 of the BIG ones. I was a kid and saw the first two overseas.

The organ uses its set of pipes and there are tuning tubes and pipes for the chapels room tuning. Same principal. Perfect solution actually..

Some of the tubes are pretty long 5 stories, start in the basement (bellow room) and finish off at 64 feet. 10,000 tubes, of course there are only two at 64 feet in the world.. US and I think Down under. AU? 

Not quite that big, or that much tinkering, LOL

Thanks,

The important words are "tuning tubes and pipes for the chapels"

It is why i called my Helmholtz-Fibonacci room tuner a "silent organ"...

More powerful than most electronic upgrade.... Acoustic is key audiophile asset, not electronic design.... Any good electronic design will sound good in a controlled room... The differences between pieces of gear will exist even in this room but will be way less impactful than acoustical change...





My second maxin in audio is now:

ONE straw kill or ressuscitate a room....

The first maxim was:

Dont upgrade before embedding everything right



Deep salutations and thanks for the observation....

Junk Science. 

Junk Science.

Read Helmholtz before writing stupidity without explanation in audio thread....It is no more advanced science now it is simple experiment for children....What is you age?

The good news if you are young, writing your  graffitis on the walls of audio thread, are you could always learn something in the future....The bad news if you are old is: it is too late, go on with your graffitis.... You perhaps will be lucky and some will call that "art" or "thinking".... Not me....
