Most rooms don’t need acoustical treatment.

He is speaking with 'all the confidence of ignorance'..if you have ever heard a good room ..evaluated and treated by a professional room guru he would change his mind in a heartbeat.Of course room treatments help...if, they are properly positioned and the rest of the room is, likewise, addressed..

@patrickdowns,

Is this yours @milpai?

That is indeed my room. I have been happy with the GIK products and the improvements they provide me. Just be careful that if you make changes to speakers or speaker placements you need to adjust them. I learned that a bit late after I changed my speakers. The new speakers sounded good. But after getting the panels in the correct spots "opened" up the soundscape. The speakers no longer seem to cast the music. All music seems to come from around and behind them. I think I have the panels in the correct spot now :-)

I have a small listening space that also doubles as a computer work station. The room is quite "lively" with no soft furnishings. I lived with it that way for years before deciding that something had to be done. Found that several large glass-covered pictures were mucking up the sound, so I removed them. I then experimented with sound absorption using beach towels taped to the walls. Once I determined what was needed, acoustical panels were ordered and installed. Best money I ever spent for sound improvement.

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

Thanks ay..

Respectfully

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.....
