What are you tweaking this weekend?

What most people ignore about SMALL room acoustic is that any change that affect the listening regular position affect also ALWAYS the nearfield position in my case 3 feet from the speakers....

I learned from my experience that the most easy to control room are small one like mine , 13 feet square, 6 feet 1/2 which claim many people will contradict even some acoustician...The room is hard to control at first yes they are right, but at the end give the better S.Q. for my 2 positions...In a room the double of it it will not be so easy for 2 listening positions at all..

Another supposed fact debunked by experience, square room are bad yes, but you can cure them and even take advantage of this...the bass for example of my 7 inches speakers drivers Mission Cyrus move my body and almost the wall IN A 13 FEET SQUARE ROOM...I disconnected my only Kreisel woofer long ago...

Acoustic is the sleeping princess, the pieces of gear are only the seven dwarves...

Kiss the princess not the dwarves.... 😁😊

Dont listen your amplifier, listen to the room..... 😁😊

Am i the only one who understand acoustic WITH HIS EARS and dont give a damn about an upgrade at any price? No it seems audiotweak know that also , he is the only one that give me an idea....And the OP yes if i remember his posts...

I made my last upgrade this evening with empty paper rolls...

Think about that...

Some Idiot which had never read about acoustic mocked me many times and i decided never to post photos again.... And when this someone give me a "tin foil hat" the same sheep consumer dream probably about 100,000 dollars amplifier..

This world is crazy because freedom is ignored and knowledge too....

Knowledge is not science and no, science is not technology....

The results are very good...

Acoustic is indeed the sleeping princess.....

I already figure it out for the multiples tubes and already juste made it...😉 it work...

I already used Helmholtz difusers with pyramid of closed tubes but you suggest to me something new: using them near my listening position... Modifying the waves flow there is crux....My soundstage is better than ever and the listener envelopment too.... Few minutes of work.... Thanks for the suggestion...but open tubes with a funels inside will work too... i will experiment...

I used a wood screen with diffusers and absorbing materials ans reflecting one in some ratio...The screen is  inclined in a certain angle behind my chair and this concentrate the soundwaves.... It is like listening headphones but the sound is in the room but at the same time near me.... I will never use an headphone now for the rest of my life....

Thanks...

Thanks i already tested some tubular smooth cylinders around my listening position...

Open at the 2 ends...

It is modifying the laminar flow of air around my listening position.... The image is better and the listener envelopment is better...

I will make them better if i could add a direction for the flow with some funnel inside each tube at each side of my listening position, and in the opposite direction for each pair of tubes...To help EACH one ear for the first wavefront coming from each speaker... Has principle...

cost: peanuts...

Mahgister,

The visual idea is to remove or work around the interference in front of your listening chair. Provide materials that have low shear velocity but are smooth not rough. Move air to you from behind the scenes..That’s all for now, run with it and see what you can hear.

Thanks for the cues....

I finished my room and mechanical, electrical and acoustical controls months ago...

But Alas! you just submitted to me a new idea :

Assembled 4 more LAMINAR CONTROL DEVICES. My additional prediction as to placement was a mixed bag. These placements raised the soundstage too high and placed an acoustic tail over and behind my head. I already have one on the top of each speaker and 2 at chest level on my Sistrum Rack.

I then added 1 each on the speaker stand near the floor level and another directly on the floor at the speaker center.

The ones near or at floor level increased bass clarity and probably reduced interferece from the carpet piles. The ones on the rack and speaker added clarity like a comb filter with no additional brightness just more texture.

Next will be to add 1 to either outside edge of each speaker or if this is a negative place these same ones on the floor.Simple device with easily replaceable and removed results.
