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

I will check into the 703 material and see if the Mrs. can do something with it aesthetically wise.  My daughters house has the vinyl planking and it is really noisy.  Echos like crazy in her very large room with her Sonos setup.  That is what I need to avoid.  Hoping someone with the items I mentioned in the original post will chime in.  -John

An interesting thing about the example in the link I posted previously is that the builder used an edge hardener instead of wood boards.  The end result appears to look pretty good so that may be a viable option instead of spending money on wood and mitering/connecting the edges.  I have not done it myself but I thought it looked like an interesting and easy approach.

I don't think 45 degree angles and mitering is necessary. To each his own, though.

Nails and glue - spray glue used to hold two 2" pieces of CW 703 together - and a visit to a fabric store to buy cool cheap cotton fabric to match the decor.

Mostly they blend in and don't stand out as they reside in low places up against walls or in corners. 

The 703 stuff is really just a few hours of work with a suggested mask with gloves, glue, utility knife, and hammer and nails. Oh, yeah, I painted the wood black and then stressed the edges so the panels look old.

Anything you buy is going to absorb far less sound than the 703 panels and cost far more. 

Sound diffusers, however, should be purchased as they are quite cheap (Etsy has some from Ukraine that are cool and really inexpensive) and while only generally a thin piece of wood with foam on the back, they serve the purpose well.

With those Infinity speakers, the bulk of your sound waves required to dissipate will be low frequencies. Hence, wall treatments (I think of them as say higher than a couch) will be for higher frequencies and require far less to mitigate). Maybe only need to diffuse them.

Soft furniture (bigger the better), rugs, bookcases, etc certainly do help with bass waves that hang out in the lower regions, but if you take care of trapping and mitigating unwanted bass waves, the higher frequencies (ones that bounce around the room at higher than couch heights) should be fairly easy to understand how they manifest themselves within your space.

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.
