Room Treatment


Hello All

I have been doing some research on room treatment and am not really sure how to proceed. I am listening in a 12’x 20’ x 9’ living room with the speakers on a short wall. Have recently updated equipment and now want to extract better performance. Has anyone here had GIK advise them what products of theirs to start with?  How many people actually take room measurements before proceeding with treatment? 
I think i need to start with front corner traps, minor first reflection point treatment and at least 1 good trap on the rear wall. thoughts?  
Thanks

Stillpoint Apature panels 2 at the first reflection point will give you the best sound by far.Not cheap but worth every penny.
