Thank you. Just one more question if you don't mind: I'm right now looking at the room mode calculator from John Brandt, and while I am not entirely sure how to read all this chart, there is a part says "CONTROL ROOM BROADBAND TRAPPING" and shows some frequency with trap depth MINIMUM, also...

Oh I was just talking in general in acoustics. Yes I will follow advice and think twice. I am in US and I did see that date sheet somewhere else, just that on that forum there was someone saying JM representative gave him a different numbers... and no one knew for sure. I will try to make...

Thanks for an informative answer. I know my questions were not as specific as it should/could been... and I also know there is no perfect answer, and even when following rules and laws it could differ a lot in reality in this field. Even so I think it is worth trying lower GFR material for my...

better yet... tear down all walls and have no reflection at all! lol

My room is 12' x 10' x 8', and while I don't have a way to measure nor I know the exact units and numbers and terms to use here.... I am trying to control low ends below 300hz, and was hoping that I can reach somewhat decent numbers at 50hz. Reason I am saying this is that I know small rooms...

When I was searching I found this post: https://gearspace.com/board/bass-traps-acoustic-panels-foam-etc/1056941-20x20-inch-soffit-bass-traps.html , and here Ethan says fill the cardboard with fluffy. I think I saw more posts by him or by others, but this is the one I could find for now. I was...

Ok maybe not exactly contradicting what you said since you also mentioned need more stuff when using soft material. I am really new to whole this acoustic, and what I couldn't understand is the part when you said any bass trap need rigid insulation. I think saw some other people, the famous...

Even for the thick soffit traps like about 16"x16"? I saw some people say the opposite, so I would love to hear your explanation here. Also was wondering how much of mass or density you are talking about when you said rigid insulation.

Oh sorry if I wasn't being clear. I was trying to compare soffit bass trap using fluffy insulation against rigid pipe insulation. Or were you saying it is better to use denser material for both? Sorry English isn't my first language.

I know acoustics differs every room and every sound, but do you have any rough idea of which would work best just for sake of low end below 300hz: stacked wrapped fluffy insulation, DIY soffit using same fluffy insulation, or the tube trap you mentioned? and do you know what material people...

Thanks for letting me know. I did change my mind after reading other replies and more online. I figured DIY soffit bass trap would work better and save me more money. I will also make a 3" or 6" thick panels using Rockwool Safe'n'Sound. Couldn't find any OC703 in local stores and online shopping...

I sure will. Thanks for the infos.

Thanks for the reply. After reading all the comments and little more on the web, I think I will try to build a DIY soffit bass trap instead of stacking wrapped insulation. Figured making a soffit would be a lot cheaper and more useful. Do you by any chance know if their R value is anyhow...

Is it the pipe insulation DIY one? I know just bags of insulation would be as nice as the well made cylinder bass trap, but do you think it would still help in small room? Mine is 12' x 10' x 8'

I have a small room too, so this does make me concern whether I should do it or not... I have a 12' x 10' x 8' room, how do you think it would work?
