    I was watching youtube and they take you to the whole process of building sub enclosures with fiberglass. Summarizing the process, they make just about 4 walls of the enclosure with MDF, they add some rings where the subs are supposed to be. Then add a piece of fabric really tight. The fabric...

    I want to begin to acoustically treat my HT room. I live in SE Asia and cannot find rockwool or rigid fiberglass insulation. I can find plenty of pink fluffy insulation, though. Are there any substitutes for either rockwool, or rigid fiberglass insulation? Or can I pack in the pink fluffy...

    Hello - I am planning out a small home theater, 7 1/2 feet by 15 feet long. The current building has concrete walls. To make it the best sounding as possible, I have read that acoustic panels are good. But is there any type of material I can insert in between the drywall that will be installed...

    My front speakers are very close to the side wall. I plan to place 2inch or 4inch compressed fiberglass (2feet x 4feet) panels on both side walls. Is it good practice to place panel just next to speaker on side wall? Is it advised to use 2 inch or 4inch panels? If I need to place on the...

    So, I know that I don't know anything about lining already....... :bigsmile: What is the best way to attach acoustic fiberglass to MDF? Trying to finish a couple projects (will post build threads...) and having a terrible time. I've tried a couple spray adhesives, including 3M 80 which is super...

    I'm getting ready to insulate my theater and have a couple questions. On my front wall where the screen will be I ended up building two walls. Mostly because of a sanitary cleanout that was messing with the symmetry of the front wall. It still isn't ideal but its the best I could do and...

    I started a ht in the basement. Was going to be really simple but when I started researching insulation its getting down to a science. Part of my basement is above ground with regular framing and osb. The builder had insulated with unfaced fiberglass and covered with plastic. I found mold...

    Hi all, This is a common question, so perhaps some might find this interesting. When we’re looking to soundproof a partition (wall or ceiling) we’d like to introduce Absorption in the otherwise hollow wall or ceiling cavities. Foam is a common consideration, however not appropriate for what we...

    I'm trying to understand the use of acoustic fiberglass in the overall design of my subwoofer. I think it is used to reduce internal reflections but my concern is about the internal volume. The design I'm copying uses this material and I haven't been able to determine if an allowance was made...

    OK, In the planning stages of my DIY sealed sub. I am doing a 3 cu ft sealed enclosure. What is the best thing to use? 1. I HATE working with the fiberglass stuff 2. I ALSO need the box to be as BIG as it can (I understand that filling a LOT of polyfill will give this effect, how much do...

    I've read several sub building threads where fiberglass insulation has been suggested as a damping material for the interior of subs. This could potentially be overly cautious, but I see this as potentially hazardous. Fiberglass insulation should really be restricted to sealed applications...

    I ran across some USG ceiling tiles in Home Depot that appear to be made of compressed (rigid) fiberglass with a thin perforated white vinyl on one side. Here's a link to what I think they are...
