  1. How trustable is fiberglass to build home theater towers?

    DIY Speakers
    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...
  2. Rockwool and rigid fiberglass substitutes?

    Home Audio Acoustics
    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...

    Home Theater Design and Construction
    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...
  4. Planning to put fiberglass on the side of the front speakers

    Home Audio Acoustics
    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...

  8. 1" rigid fiberglass in theater build...

    Home Audio Acoustics
    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...
  9. Hesitant to use fiberglass again after finding mold

    Home Theater Design and Construction
    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...
  10. Foam or Fiberglass for soundproofing?

    Pro Audio
    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...

    DIY Subwoofers - General Discussion
    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...

  14. Fiberglass Insulation in Subs

    DIY Subwoofers - General Discussion
    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...
