Small room studio - Croatia

[SynTh]

Greetings guys,

I tried to do my "homework" and read as much as possible answers before posting, but now I just need some advice. I'll be very thankful if someone can look at my post and give me some advice or even confirmation to my doubts.
So, just to say that all of this is my free time hobby, but by profession I'm electrical engineer so I have some knowledge of construction and calculations.

I plan to have small studio room (live and control room would be in same room) just
for my own projects with my band (worship music).
Room is on 1st floor of my house with dimension 4,2x2,9x2,5 m (~13,7x9,5x8,2 ft), and under room is just some unused place for storage, so room floor isn't something to consider for isolation.
Room floor is 7mm laminate then 3mm thick laminate isolation then 7cm concrete, then 5 cm Styrofoam and 15 cm of concrete between this ground floor storage place and my room.
Room walls are cored bricks with 4cm mortar over them and room ceiling is same combination as room floor (there is one more unused room on the 2nd floor above my room).

In atach I put Sketch Up model with plan for acoustic treatment and one photography of current room layout. So I plan to leave current room layout same, but just to make some acoustic treatment.
For first reflection point i plan to use some Auralex absorption Studiofoam® Wedges 2″ and for bass traps i plan to make it on my own with 10cm thick rockwool in wooden framework and textile over front panel.

I didn't make any acoustic measurement, so all my plans I based on information i collected on this and GS forum.
I would be thankful if someone can give any kind of advice... is all of this good or I can make some improvements?

Hi "SynTh", and Welcome!

I tried to download your files, but it said I needed authorization. Please put your files in the public domain, where everyone can access them without needing to get authorized, or login, or sign up, or whatever. Photos and files that are small enough should be uploaded directly to the forum, and files that are too large for that (SketchUp models often are) should go some place that has open access for anyone who wants to download them.

Apologies,

I always use google drive for sharing, but this time it was just my mistake.
I forgot to apply open permissions to this files. Now is fixed.

Thank you for your answer.

I'd be incredibly grateful if someone can take a moment and give some kind of advice.

So I plan to leave current room layout same, but just to make some acoustic treatment.

I would suggest that you replace your speaker stands with something a lot more massive (heavy). The ones in the photo are very light and flimsy. Speaker stands must be rigid, heavy, and decoupled.

You also need to push those speakers right up against the front wall.

Apart from that, you seem to have your room geometry set up correctly, but it would be good if you could get a smaller desk, and raise your speakers just a bit (maybe 4 cm or so), to help reduce desk reflections and comb filtering.

Your acoustic treatment looks about right, but you might need more bass trapping, and you definitely need absorption panels between the speakers and the front wall.

When you have all of that completed, I would suggest doing a test with REW and posting the results here, so we can see how well that is working.
