Room treaments

I am beginning to treat my listening room now.
Question what is the preferred room treatments for more seasoned audiophiles with dedicated rooms. It seems there are quite a few members that have great wisdom in this area and we newbies would welcome feedback.
Absorption or difraction/ diffusion or combination of all

Here is what I am thinking to begin.
Absorption at first reflection points (using 2 x4 acoustic panels on side walls)
Thick carpet between speakers and listening position
Ceiling Absorption( same 2 x4 acoustic panels)
Back wall combination of difraction/Absorption
Front wall Absorption.
Corners floor to ceiling bass traps.

My room is 12 wide by 18 long and ceiling is fairly low at just under 7 foot
I built the room specifically for my 2 channel system .
I have Salk Sound SS-6M 2 way monitors with all YBA solid state seperates
I will play around with absorption and difraction/ diffusion.
I made the diy 2 by 4 sound panels and will play around with placement but I was thinking more absorption at first relation points rather than diffusion.
On the back wall behind my listening chair I ideally want both absorption and difraction so I might experiment with some DIY diffusers and maybe a home brew quadratic diffuser. I have seen a few designs on you tube that I might try.
But as far as corner treatment I haven't given that much thought. All the bass traps I have seen take up a lot of re estate. 
I guess it is a fine line between a lively room and a sonically dead room.
I appreciate the advice

I have a theater room your size.  I added 4x8 wall panels from 4seating.com.  I have plush carpet on the floor and nothing on the ceilings.  Believe it or not it is almost to much.  It is great for the theater room but not for a two channel room.
I just added cinema round panels from Vicoustic Acoustics in my very large great room where my two channel area is.  My room is 25'w by 40'L with 16' ceilings.  Just adding 4 2'x8' cinema round panels helped my room substantially.  Vicoustic provided a whole analsis of my room after providing them a video.  I have used GIK and Audiomute.  With your low ceilings, I don't think you will need that much.  Do it in stages....see how it sounds.

Reach out to GIK Acoustics for one on one free consultation. Once they make their recommendations, do it in stages. I did my room in three phases!

I love GIK.


From what I’m reading I suggest the following: More diffusion and don’t ignore the floor between/behind the speakers. Lot of hash lives there.

Do bass traps carefully. You can overdamp, leaving you with a lean system, but smoothing out the response is critical to a good system. If you can measure as you go you’ll be in a better place.

If you have no bass resonances, or well controlled one's you are done.

Best,

Erik

GIK is excellent, but I'm using Vicoustic now. Check them out before making your decision. https://vicoustic.com
