Could you please help me with placing my absorbers

[middletom]

Dear fellows

Soon, I'll have my first little recording and mixing room. I added a picture of the situation. I have already built some nice DIY Absorber plates + 2 resonators (don't know the correct english term for that one. In German it's called Plattenresonator or Plattenschwinger)

Were would you place those Absorber?
2x: 1.80m x 1m x 6cm accoustic Rockwool
3x: 2m x 1m x 6cm „“
2x: 1m x 60 cm x 6cm „“
1x bookshelf 2m x 2m
2x wooden resonator

Hope someone has the time to help me!
THANKS

First, you should rotate your setup so you face the window at the bottom of the drawing when listening. More here:

How to set up a room

The above article also explains where to put absorbers for the side-wall and ceiling reflection points. Then you'll put bass traps in as many room corners as you can. You need more traps than you have now. Maybe 2 to 3 times more. A bookshelf is not acoustic treatment, so put it in the rear of the room, maybe along one of the side walls. I can't advise you on your resonator bass traps without seeing a photo or a better description.

Thanks Ethan

It's great having such an experienced person to help me
Of course I already know your site and your videos. And I read and watched them nearly all the way through some time ago.

I've chosen the monitorposition that way round because I've heard in another thread that it is more important to have equal distance to the sidewalls than to the backwall. And because my room is L-shaped, I thought, this would be the best way to start.

So I'll turn around the Mixingposition. Sweetspot is around 1.5m away from the window now.
The bookshelf I thought could act as a sort of diffusor... maybe I was wrong in scientific terms...

the resonator is a wooden box with Rockwool in it and on the front side, there's a thin plate, that resonates - if I remember correctly - around 60-70 hz. Which was a problem area as I did the testing after your Videoguide with a sinus sweep.
Where would you place those?

Could you please comment the new picture?

Thanks!

Well, it looks like you're symmetrical now, and the rear wall is now farther behind you.

Probably on the front and/or rear walls.

The new layout looks much better.

OK. I'll check it out.

Thanks Ethan!

Any other opinions?

Nothing to add other than seconding Ethan's advice. He's 100% correct as usual...if you do it his way you'll be just fine!

I'm just wondering.. I believe, that he's absolutely right. I just heard a lot about live end, dead end... Wouldn't that be an option too? Or is it just an internet myth?

Thanks for further comments.

Live end / dead end is sort of old school. It works fine! But it's not really necessary to make the entire front of the room dead. What matters most is treating the specific reflection points. Some pro studio designers like to keep the entire front of the room very live, but that requires side-wall angles of at least 30 to 35 degrees. You don't have space for that, so just stick what the tried and true.

Your room is pretty small for live end/dead end anyhow.

OK. Thank you guys. I'll set it up that way and do some measuring.

Thanks a lot for your advice!
