Hi, guys.
So here is my REW Result.
Feel free to give me some tips if you think I can improve it. Thank you.
I am also attaching the mdat file as well.


My Room's REW mdat file link is here.

 

where is the waterfall?

 

I have already added the mdat file link.
Once again, here you go. https://www86.zippyshare.com/v/sVtGY1ka/file.html

Also here are the waterfalls

 

let me guess, the room is 2,40 x 3,20 meters?

 

How did you guess?
But anyway it is 3.81*3.20*2.5 (L*B*H) in Meter

 

Also, here is the E66 official frequency response.

 

its no guess, i interprete the spikes in your curves (3ms ~ 1meter)

 

ETC Curve right?

 

yes u can see it in the first 2 curves!

 

Lower end seems good.
Most "usual" rooms get a big spike at around 50 Hz : this one is clearer than usual

Two big spikes at around 150 Hz and 350 Hz (low mids)
Those could be probably "fixed" by moving sound source in the room.

Try moving speakers away from wall and/or put them against the next side wall ... and test again.
If you can, of course

Well, all the walls, ceiling, floor and corners have Basstraps. I am adding some pictures. Hope you will understand.
This is the best result that I can get.
Sadly this is the best Frequency Response I could get.

 

There's a theoretical sweetspot at around 37.5% of your room lenght (in your case 1.42m from the front wall) where the room modes should be less prominent, maybe measure around that point and see what happens?. Also, looking at your impulse response there's a little spike that seems to be coming from the ceiling, you could kill that by placing some sort of diffuser (like a space coupler) hanging below the absorber you have, should be fairly cheap and could also help a bit with the 350-ish hz peaks on the waterfall. Rt60 looks good down to around 50hz, then goes a bit too far but who cares, 50hz is overrated and probably likes that beer brand you hate. If you still want to fix that, you could replace some absorbers on the side walls with resonators tuned to that mofo, some designs out there can get the job done with little space requirements.

So are your acoustics are good or bad? Don't know. I really think at this point you could just move the listening position and speakers around until you find the best results and be done with it. Also, it looks awesome

 

Here's what I am currently getting at this moment.
I have plans to improve it further.

 

Well, I installed Table and also put some reflection filters on the table. So here are some results.






These are all after the desk.

 

hey, i just saw in your desktop photo u have a wrong placement of the speakers, pls use them "vertical or upright, because speakers have direction patterns ( like Microphones) and beteeen vertical and horizontal is a HUGE difference!
You can avoid lots of the desktop and ceiling refections by using a the speaker in the right way...

 

Setting up the A77X in a stereo setup The A77X is designed for horizontal operation.

 

First of all, the picture here shows ERIS E66 which is supposed to be a horizontal speaker. Similarly, A77x is also a horizontal speaker.
Also, here is my ETC curve. Do you see any reflection? Answer is No.


Again, this is with desk and everything.
Here is the recent picture.

 

Final ETC

 

Also, after a lot of discussion and testing, I will be going with Sonodyne SM300 and a pair of Sonodyne SLF312 Subs.
