Starting in room acoustics

[hardcore_gamer99]

Ok so now its time to start in treating my square room. I have dali opticon 2 mk2 and cant hear dialogues clearly in 4k blurays hollywood. I know behind the speakers on front wall we need absorption panels. But what specification should i see to buy it? Also why some brands are cheap like mmt while viacoustics is very costly? Will cheap work for my room if i am just starting. If yes, how much thick it should be? what type of wool or material is good? what is nrc and how much do i require for opticon 2 mk2 fronts? And yes how much length and width do i require ? Also i have gates to sides of speakers do they also need panel?

Foam is useless. Might clear some high frequencies but useless in mids and lows.
Of the mentioned timber acoustics is good. But it is only 40 kg/m3.
It works brilliantly for highs and mids and good with lows.
Go with a diy panel with rockwool in the density between 60-80 kg/cu.m. This is the sweet spot.
Above this density, highs get reflected and lows gets superbly absorbed.

2-3 inch would be fine. Also, give some air gap between the panel and the wall.
For floor, use some nice carpet.

DIY cant do. Any other brand you suggest?

The size of Timber acoustics is good. Their arc is 0.9 which is good.

I’m glad you are working on the room acoustics. This is a vast subject and you will have to take it step by step.

Since you are willing to spend on the acoustic panels, I would recommend getting a calibration Mic like UMIK-1 or borrow it. This will give you an objective analysis of the room and where you can tweak.

You can try some interventions like acoustic panels at first reflection points, bass traps at the corners, and diffusers. This will take some trial and error. This is largely subjective and might not be the effective way, especially for a beginner. One simple way to find echo and reverb is the clap test. Just clap and notice the echo. How much of a reverb do you get. You have already mentioned that speed lacks clarity, that already shows that there is significant amount of issues there.

I would second that acoustic foam won’t help that much. I have the Timber Acoustic panels that you linked. They do help in the mid range and highs. Remember the low frequencies are very hard to tame. First tackle the frequencies above 300 Hz, they will significantly improve the clarity.

Foam is the only recommended solution for window glasses and to an extent for the second or third reflection points.

Foam with acoustic / canvas cloth makes a good absorption for stereo.

I am a dirac live user with bass control. I have umik already. Have null of 30dbfs in 71 to78hz area. But wantcto startvwith front speakers for now to treat using acoustic. Which model to buy

Since you already have UMIK-1, why don't you post them here. Also, drop it into ChatGPT for analysis and possible tweaks. It is surprisingly helpful. Much more in-depth and detailed for a beginner to grasp though.

i somehow treated 45hz massive null by moving sub and it became a peak of 8db does not matter much. but the thing is bass is not that good to my ears, earlier in saw 2 movie this woman opens the yellow small door with her both hands that gave good deepness but now its missing though null is gone at 45hz

i recently followed some guy`s recommendation to divide length and width of room by prime number and place subwoofer speaker and umik1 in these areas. Like 1/3 of width combined with 1/5 of length. but not getting that deepness in bass now , moreover i forgot what my previous location was damn!

All this is captured from rew. after dirac live bass control 80hz . I did dirac live again today but that sound pressure has gone down . dont know why. like in godzilla monsterverse 4k collection that pressure is missing in many places.

dirac live bass control is killing bass at 30hz area while with only dirac live filter its good. see blue line. why is this happening
