Hey guys!

Need help with my room... I'm attaching my 3D model of the entertainment room.

All windows and sliding doors will be covered with black out curtains, which I haven't integrated with the 3D model with.

I need help with the following

1) Are my speaker positioning OK? It's a 7.1 set up
2) Where will I need to put acoustic panels? I currently have 4 but it looks like I need more.

Thank you guys!

It looks like the left and right are way too close to the side walls and without knowing more about the polar response of those speakers may benefit by angling in toward the listening position. If that is a hardwood floor think about a big area rug in front of the seating area.

Thanks BIG... When it's all set up, I'll definitely angle them towards the listening position. And also forgot about the area rug. (The floor is engineered wood, so definitely it will still bounce from there).

I'm thinking... the first reflection points (as I have read in the past few minutes) will play a major factor. Will heavy drapes be effective in taming the said first reflection point since the FR speaker will directly reflect into it.

Depends which frequencies you are trying to tame, but generally speaking, curtains won't amount to hill of beans in the problem frequencies, and eliminate the ones you want to keep around.

Well for starters I honestly don't know much about frequencies... All I know are the basic stuff like speaker positioning, and the need of Acoustic Panels and Drapes over Windows to avoid reflections.

My questions still stand... as to what extent can those drapes help me in taming the reflections (first point) and where the acoustic panels should be placed.

Use the mirror method to determine some side placement. Regarding the drapes, they will attenuate the high frequencies, but they will do nothing, or very little, for mid bass. Unfortunately, this is where some of the speech range lies.

Ouch. If that's the case. Then the room will be far from acoustically treated? I can't do anything since there are windows... I'll follow what have been said here. Mirror technique, rugs on the floor... but will it matter if the drapes won't do the job?

What else can I do to improve the acoustic?

You can always put panels on stand or attach wire (or loose weight chain) to the ceiling so the panel is hanging in front of the window.
With that said though the largest problem in a room like that is not only the early reflections but also low end response. For this you are going to need a good amount of bass trapping in corners. You can use the following as a guide for set up.

The following is a video a dealer did (sorry English subtitles) that show with and without treatment (recorded music) in the room (starting around 3:30 in the video)

Thanks for the resources!

Going to look for bass trapping in corners.

Sorry to bump this... But I've had four acoustical panels on corners. They have "feet" though, so they are slightly elevated. Shall I remove them as there are gaps underneath them?
