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..
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
