Hello all, new guy here.

I’m a hobbyist who wants to start messing around with film scoring/audio post production, and maybe record some songs (rock or folk), and also play for fun.
I know my way around DAWs and have some technical knowledge, but not much experience with acoustics.

The apartment I’m renting has a room I want to dedicate to this, as it’s a rental there’s no crazy amount of things I can do for acoustics (can’t hang stuff from the walls for example), so I was thinking about things I can take with me if I move in the future.

I was hopping you could help me with your knowledge/experience.
I’m trying to find out the following:
– Best near-field size for my room dimensions.
– Best placement for my table.
– Things I could do to reduce reflections and not bother the neighbors too much.

– Best near-field size for my room dimensions:
I’ve been looking monitors that can be calibrated by software to help reduce the room problems a bit.
I’ve seen the Genelec 8330 with a 5″ cone (45Hz-23KHz @104 dB), and the 8340 with 6.5 cone (38Hz-22KHz @110dB)
(Maybe add the sub 7360 in the future if needed).
I read that monitors too big for the room can create problems, so not sure If I should go with the 5″ or the 6.5″

– Best placement for my table.
Here’s a floormap:

I was thinking to put the table close to the window (it’s double glass), and maybe putting a heavy curtain I can close if necessary.
I have a 88 key keyboard that I would like to have at my table, along with some fader controllers.

– Things I could do to reduce reflections and not bother the neighbors too much.
Though I would eventually record an acoustic guitar or box, I don’t care much about the external noise as I leave in a small town without much external noise.
I mostly care about preventing unwanted reflections, resonances, and not transfer too much sound to my neighbor.
Floormap is here:

I was thinking about putting some heavy curtains on the sides, leaving about 0.30 mts of space between them and the wall.
Maybe something on the back as well?
I also saw a few DIY videos for bass traps and they recommend putting them on the corners, so that could also be it.

Now that I read it, it seems way too much to ask at once, but any help is appreciated :)

Thanks!

E, You need low, middle, and high-frequency absorption on the front and both side walls. Since you can’t place anything on the walls, you can use our broadband ACDA-10 units. They absorb from 30 – 6,500 Hz. and are on casters. Here is the link: https://www.acousticfields.com/product-category/sound-absorption/acda-series/
