Acoustic Room Treatments

Curious on this thread b/c I will soon be moving to a new house with hopefully a dedicated listening room. What budget/investment are you guys talking about to treat a room, with and without consultants? Thanks

@cooperdude6 if you're handy with woodworking, you can make the Bass panels yourself following existing material from Warp Academy on YouTube and you can make the wrapping very aesthetic enough for your listening space's vibe

"Higher density rock wool can be effective in depths from very thin to about 12"/30cm.  Beyond that it becomes increasingly reflective.

If you only have a minimal amount of room volume that you're comfortable losing, you can get some really good results by building modules that are 5.5" thick with ComfortBatt R22 rockwool batts inside of 1" x 6" x 8' framing lumber, floor to ceiling, and then air gapping them by 1" from the wall.  You get a pressure effect from the small amount of air in the gap that shifts the absorption lower than a non-gapped module.  Floor to ceiling is essential here.  If you're doing smaller modules, that are, say 2' x 4' with the same material, you'd need a larger air gap and a completely sealed enclosure behind the panel to shift the absorption lower.  Plus, with the smaller modules, your wall/ceiling/floor seams are left untreated.  Floor to ceiling all the way."

The above is what taught me all the woodworking I know now lol but I had the help of a carpenter friend. As for the measurements and DSP, did myself cos "self taught engineer who is an audio science nerd :)"

My room is 19 x 13 with 8 foot ceilings. I have a few acoustic panels to the right and left of my 77 inch Sony. Behind the listening chair a have 3 diffusers. That’s plenty for me because I use a Lyngdorf MP-60 with RoomPerfect.  Maybe the greatest name for the greatest DSP product ever engineered. It literally makes your room, “Perfect.”  Could never live without it. I run an AES/EBU cable directly out of my Antipodes K 22 player into the input of My Lyngdorf. Perfect.
