You can certainly make your own, but to work properly they must be built according to certain acoustic principles related to the laws of physics as they relate to sound waves (remember science? some here seem to be ignoring it). Surely someone here knows of a good book whioch relates such things. Egg cartons won't do it. http://www.acousticsfirst.com/articles/diskmakers/index.htm |

Anyone have good tips or suggestions on DIY diffusers? I'd like to throw some up on my rear wall but don't want to pay $150 for 1 molded plastic tile!! What a rip-off! |

the easy est way to DIY it is to buy one and make a mold and then build them from the mold. |

Rich, Very simple, very effective and very cheap diffusors are also some of the oldest designs, dating back fifty years or more. |

I don't think you are taking the R&D into consideration. Properly designed diffusors are not some kind of randomly placed protrusions. There is a science behind the funny shapes. |

More like the Romans were using them. Here're some poly types that I made. |

har har. I barely got it! It's built from 1"x 1"x 3/4" blocks of cedar, which is light and easy to work with. I just set up the table saw and had a little cut fest. I thought foam would be too unstable, and probably have to be painted with a gloss to cut down on it's absorbency. The BBC notes suggested square pvc tubing, but I thought that was a little too reflective. In the pic the rough construction was sprayed with a textured paint, but I found that if you do a neat enough job, the plain cedar looks nice and fits just about any rooms' color scheme, being a natural looking element. The variations in the woods' color is nice, and you can use the rough sawn side if you want more texture and possibly 'micro diffusion'. Total materials per 'unit' (unit=4 12"x 12" sections)is about $14.00. There is no scientific calculation to the unit size, I just figured it had to be at least that large to have a noticeable effect. |

I built some 'skyline' diffusors using the prime number theory posted on the BBC website. As you build more of these they fit togother to create a bigger diffuser, kind of a fractal thing. Here's a pic: (I hope) |

do you have a link?? |

What's the frequency range of your diffusors? How deep into the bass region do they extend? |

what acoustic difference does it make to add some rockwool layer on the bent plywood from inside or to keep it simply plain? Or to put rockwool inside the frame on the wall ? Just to bend the plain plywood would be the easiest of course ... |

It's not DIY but an interresting product, environmentally progressive, aesthetic and affordable design : http://www.mioculture.com/store/pc/viewPrd.asp?idcategory=2& amp; amp; amp;idproduct=9 I thought it makes not more than egg boxes, but maybe fill in with some material like foam ?... Is anybody already try it ? |

Hi Chris, So.. are the depth's off the slats different, or are they mushrooming out together from the base frame? Often, thinking of back wall design myself. Cheers, Kayo |
