Feedback on Costco & Amazon sound absorption panels from folks who have purchased them.

Greetings.  My wife & I have purchased a new home (to us) and I am extremely fortunate enough to be getting a 19 X 21 foot room for my stereo.  The home is getting all new vinyl plank flooring throughout.  This rooms floor will have a nice large area rug of some sort to help with sound control.  My wife has been searching around for wall treatments and found the Artika panels at Costco and a plethora of choices on Amazon.   Looking for input on users and if you are happy with your choices.  I need to keep it aesthetically pleasing so no chunks of foam glued to the wall.  System is: Krell FPB300cx amp, KCT pre and Infinity Renaissance 90 speakers for reference,

Thanks for any input to a regular guy that just happens to dig quality sound. -John

@mitch2 thanks for the DIY link

Timely thread as I’m also considering adding additional room treatments. 

I do not have any experience with Costco or Amazon vendors, only GIK - I have their 10" thick Sound blocks behind the speakers and wall diffusers.  

A couple of comments...

According to GIK, you wont get adequate bass absorption from thinner panels - it does take a lot of mass to absorb the lower frequencies.

Also try moving the speakers - it is often suggested to move speakers out far from the rear wall, however in my case, that made the bass from my from my Harbeth 40.3 XDs bloomy/muddy. The rear of the speakers are currently about 2 ft from the rear wall - much better than 5ft out. Obviously that’s my speakers in my room but it illustrates the variability in frequency responses based on speaker position alone, and it’s a free experiment.
