help with set up

[Hostility]

so this is what i have so far

Polk rti10 fronts matching center
cheap rears (replacing around xmas time)
velo dls5000r

now this isnt my house, and i didnt get to fully decorate this myself. so please be kind with comments lol.

what im looking for is some help with making it better, im looking to make some bass traps, but dont know where to place them, i have 2 corners i can place them, and hang some on the walls, i cant put any on ceiling or where the ceiling and wall meet. and im also going to build some rear surround stands but dont know how high i should build them, ive seen some where they are ear level, but have also read that rears should be 2-3 feet about ear level? and i will be building a bigger custom a/v rack soon. right now i have my fronts and rears angled right now. now should they be closer to the t.v and straight? also is it ok to have my sub that close to a corner (right now its really boomy) and the room measurements are 25 ft long x 11 ft wide x 7.5 ft tall... now onto pictures.

well tomorrow im going out to get some wood to build my a/v rack, and get some wood for speaker stands and bass traps!

Is it possible to reorient the entire layout so that it's lengthwise? That is what is desired for best acoustics. Since the couch(es) will need to be away from the "new" back wall since the doors need to open, you would also benefit enormously from not having your heads again that wall.

In a closed rectangular room, the starting point for LP is 38% of the length, for that is the best compromise as far as axial modes. I have learned here that the number can drop to as low as 33% with the inclusion of non-axial modes. Regardless, however close or far you are from that number, getting at least a few feet away from the back wall is beneficial no matter what. If you absolutely must be against the back wall, that should be one of the first places to treat, if not the very first.

If you do reorient, there's a chance that your bass will sound better, though of course no guarantees. Definitely trap the corners, whichever ones you can, but the most important bang for buck spots are the front two corners.

Hope that helps.

i have thought about that before, but im not "allowed" to lol, its not my place really, so i can only do so much, im going to be making some traps very soon, and i was going to put some in the end corners (the 2 you can see in the pictures), also i see in a lot of setups, people put them behind each speaker, is that a must or not so much? i was planning on building 4 of them to start off.

but as far as right now, furniture wise it has to stay where it is, but im going to try moving my speakers a tad, and im going to move the couch out of the way tomorrow and play some bass heavy stuff and crawl around and see where it sounds best.

ok here are some updated pics

-rear stands in place (dont mind speaker wire, once the new receiver is here, the speaker wire will be different length)
-a/v rack in place (waiting for new receiver to get here, and BD player and ps3, also the 2 4" boards on the back is so i can strap wires to it, to hide all them)
-cleaned up rack under t.v so it looks more clean
-moved teddy's out of the room (some) lol
-subwoofer not sure on final spot for it, but im thinking where its sitting right now (its just pushed there for now as i was moving everything)

Corner traps and panels behind the speakers are a good start. The ones behind the speakers are for SBIR control (uneven bass response due to proximity to a wall).

You might also look at a couple thicker panels behind you since you're so close to the wall. You're sitting right where all the bass builds up.
