My question is do I need to first complete the rest of the room so all corners are treated. that will take about 24 panels. Then reshoot? Would it help to do all the front wall panels at 6" instead of four or is that 2" futile at 70h and 250hz? I trying to figure out if a tuned enclosured will be needed. I could build the mix desk and position up on a tuned trap. Just an idea. Any direction. thanks |

Will let you know what happens once I move and get the rest of the corners in the rear and additional panels up front complete. But did want to note that the 5' listening positon is me sitting back int he cahir. that point is 38% from the front wall as 50% is 1.5' behind that. With small rooms the rule doesn't seem to work.

thanks so much for the advice. Good news to report! |

QUESTION? Will treating the back half of the room improve things any? |

Can I build a fairly shallow foot print membrane box for the front wall ceiling and get this worked out? |

I read on RPG's web site, no matter how thick you go there isbn't enough air movement in the corners to absorb the energy using fiber panels at these freq. And tuned is the only way to do it. Your thoughts? |

I said front wall ceiling? Is that what you meant too? |

What you need in your room is a mix of both resistance to flow treatment (rockwool) and tuned membrane systems (free membranes, not glued to the rockwool). You need to interface them with air cavities. Start with your backwall now. This is where you really need to do something now. Treating your back wall and corners is more important than any treatment on the front wall or ceiling. |

Sorry, I must have been on crack, I have no explanation for this. In the grand scheme of things, it's not possible to have too much bass trapping in a room this size. You could line every single surface with 705 two feet thick and it still won't be perfectly flat. (Though you'd get pretty close!)
I would not used tuned absorption in a room that size. Tuned traps are also more expensive and much more difficult to implement. The main problems you have are due to close proximity to the room boundaries. This means that small changes in placement - loudspeakers, instruments, your ears - changes the frequencies of the peaks and nulls. This is why you need broadband absorption more than tuned. The problem is not one low frequency that can be targeted, but many low frequencies. --Ethan |
