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

I would like to comment that after putting up 12 703 panels in my room,was one of the most transformative experiences to date. And truly, one of the most inexpensive tweaks that one could do. Getting a fabric that breathes such as burlap is just as important as the fiberglass panel. A good measure is to put the fabric up to your mouth and breathe in and out. There should be no restrictions in your airflow. The sound has to get into the fiberglass to do any good. Along with a nice thick rug, putting panels on the ceiling, known as clouds are just as important. Seems that you have a Costco it stands a reason that you have a commercial insulation distributor. I was able to get a better price than what is available on Amazon. At the end of all this, if you are not a DIY kind of person, even though this is a level One difficulty.  I recommend that you use a company like GIK or it’s equivalent. What’s good about these guys? Is you tell them about your room and they shoot you a suggestion based on science 🧫. Taking the guess work And research one needs to do. good luck in your endeavors, such a lucky man to have such a blank canvas. 

All good suggestions. I bought wood, insulation, and fabric, then hired a handyman to build and hang the panels. 

Insulation is light.  Simple butt joins on wood is sufficient and wood only need to be 1/2 to 5/8.  Get a cordless 16 or 18ga nail gun and glue.  Secure behind with cardboard. Simple.  Absorption isnt about mass.  Work with wife to staple a fabric of her choice.  Four hands help.  See 2ft x 4ft panels on my system page.  I have another decorator fabric one on the wall behind my head / seating spot.  Helped alot.  I used 3 in with mylar side out.  Cut others to 1ft x 4ft and wrapped in cotton color that disappears wall for 2 corners too.  Knauf brand has spec sheets showing attenuation and frequencies for thicknesses, densities..  

Hoping to derail the discussion, but how do you know where to place the panels?
