Which is better foam or sound absorb insulation? Insulation, Roxul for sure. They use it in elevator shafts to deaden the sound |

Just ordered the silk screen posters John Wick 1 and 2 to have a go at making the panels, i think i have a good idea using LED light behind the screens to illuminate the print itself. cheers |

Most rubbers reflect the sound and don’t allow it to pass through. Foam allows the sound to flow through too quickly, not dampening the sound.Heat is the by-product of an absorber. |

Foam isn't too different from Corning panels, Rockwool/Roxul, or the pink fluffy insulation but as you approach perhaps 100~200 Hz and below foam absorbs much less (is a much worse absorber) than those other solutions.

Yes, but it depends on the panels. ATS makes theirs with a plywood back, so mounting away from the wall does nothing. |

Thanks Nick, great info, After a little research ............ you are correct regarding the fibre insulation, must absorb instead of bouncing off. Found these links and spoke to them on the phone, and this is exactly what i was looking for, you stretch the silk screen over the fabric and it locks in. www.acoustica.com.au/product/kliptex/ www.acoustica.com.au/product/hd-high-density-acoustic-batts/ |

So would there be a benefit to drilling or cutting large holes on the side of the frame before installing the fabric?

Something like MDF or Russian plywood is some tough stuff, so bigger holes are okay. Soft pine, not so much. I was going to use 3/4 oak plywood. I have a few long pieces left over from building my kitchen cabinets. I could also cut in long "slits" down the sides. Would there be a benefit at all cutting in slits or making wholes to the sides? I am assuming that these cuts into the sides would still absorb some of the sound. |

I wouldn't worry as much as holes or slits in the sides as having them off the wall, I have seen Roxul just wrapped with Material and hung not even using a frame at all, but the minimal amount of wood used making the frame works fine, at least for me, having my panels in my room makes a very noticeable difference.

If you have a backer board, like certain brands use in their panels, then holes in the sides would help. If your panels are open on the front and back, then hanging away from the wall should be more effective and I wouldn't worry about holes.

Thank you all for the input. I greatly appreciate it! Now comes the hard part of picking the material I want to cover them. Will post pics when I am done.

I have just received my silk screen poster of John Wick,i'm a little concerned how tightly the woven the material is.
Does anyone have any ideas if the sound will travel through this material? don't want to waste my time making a frame if it's not going to work.
Cheers

Cheers Hold it up in front of one of your speakers with music playing and see how much it affects the sound you hear. Little to no difference and you are good. Big difference or muffling, not so much. |

Cheers You can also try blowing through it, as long as air can travel through it you will be fine. Chad |

I used two 16W X 48H acoustical fiberglass's panels stacked floor to ceiling in each corner (forming a triangle) and filled the space behind them with triangular shaped foam blocks. Seems to work well as an absorber and as a bass trap and they passed the wife test.
