Greetings, has anyone worked with air conditioning fiberglass duct board for room treatment? Raping framing and hanging/anchoring Thanks.

Visual aspects of materials do not correlate with acoustic properties.  Use only certified test data.  I had 10 GIK 2ft x 4ft 244 panels in my listening room.  They were inexpensive and highly effective (in the right settings).  My room frankly was not one of those, it was properly proportioned and they barely helped.  But in lesser rooms they made immediate improvements.  Getting a right room is the second most important aspect to getting good acoustic results (after good speakers).

Besides loose fiberglass is harmful to your lungs!

Thank you for your post JLM. Just finished a total home remodel and am starting in on putting the listening room together. I'll be exploring GIK and others.

GIK Acoustic panels are good value and work as described. Though as you noted, their effectiness depends on whether or not you have existing room issues due to a less than ideal room. As I live in a smallish apartment, my system is placed in front of a staircase along the long wall. Oddly enough the staircase acts as a sort of crude diffuser, and there is ample room on either side of my speakers - so I don't have to address the first reflection point. And my racks are placed on a timber landing which helps isolate them from floor-born vibrations. Though as my sofa is placed hard up against the rear wall, I plan to install Acoustic art panels at some point (likely GIK) to replace my current framed artwork. I also agree that choosing the right speakers to couple to your room is the most important priority. In my case, I have an uneven front wall and have to place my speakers fairly close to my landing, so I plan to go with rear ported speakers which come with acoustic foam bungs to tune the rear output.

Work with your room before you start spending money on room treatment. Here is a link to the method I use, its call the Room Coupling Method https://pt.audio/2025/01/05/modified-room-coupling-method-for-speaker-positioning/
