Hi,
I have a small room 3.2m (10ft) x 3.0m (horror). Biggest modes about 104-115 Hz. Bought 8 thick primacoustic absorbers - not mounted yet. I have 2 bookstands as well - filled with various stuff.
The question is :
should I put them on sides as first-side reflection absorbers or on the back wall and use absorbers on sides?

both locations.
Bass traps are important, if you can't afford, build from foam based matrices of old sofas or something... just get those corners filled.
hmm... just noticed you're located in a square room... I guess you're doomed!

I have 10cm thick broadband absorbers. I mean the furnitures.. back or side ? I can't have both due to asymmetry.. The rest of empty walls will be treaded with panels.
Room measurements attached, panels are on the floor in the corners (not mounted yet). Look at this.. it's not that bad
they work.. 100 hz mayhem is not present.

Ah, I misread... Bookshelves are considered diffusers and are probably best on the rear wall.
I'd put the foam panels on the sides and the back off the video monitor.
The graph looks kinda bad actually... if you're about to use the room for mixing or production (mastering not included)
edit: spelling mistake

I'll try with bookstands on the rear wall. Thanks...
No foam here... it affects only upper bands that is not the biggest problem in small rooms.. absorbers or traps instead.
Btw. I've read some advices to have at least 15 cm distance between wall and speakers. I observed something opposite. The closer to the wall the better.. now its about 1cm.

You can't be sure, if it seems "pleasing" sounding doesn't mean it's correct.itoa wrote:Btw. I've read some advices to have at least 15 cm distance between wall and speakers. I observed something opposite. The closer to the wall the better.. now its about 1cm.
You need to make several placements and do measures after each.
Usually the best measure will take teh cake.

Yes I did measurements each time. 10-30 cm from the wall effected in 2 deep notches.. they disappeared when I put them closer to the wall.
The attached measurement tells me nothing :/.. There are a few wide notches / peaks

Maybe it's because the room is square format.
Now, try temporary placing the acoustic treatment materials in key places such as the sides, corners and back of the monitor and measure to find the best spots for the materials. The graph should even out a bit more but also you'll get rid of other acoustic problems as well.
The sides are relatively easy, this might help (2:45):
