Hi, i have a 16.25 X 12 X 8 foot control room that has a severe dip at 80 Hz. i already have a ton of Ethan's RealTraps traps in the corners, ceiling and walls but obviously need a serious trap on the rear wall, as he has suggested to me. the speakers are 30 " off the front wall and my mix position is another 3 feet in front of the speakers. I've ordered a few boxes of OC 705 and will build a 6'wide X 4'high trap that will be 10" deep with 6" of 705 and a 4" air gap to the wall. is this the most optimum design? is 4" of 705 with a 4" gap enough? i don't mind going with 6" if it will be more effective in the 80 Hz range. thanks for the help, David |

Anything LESS than 3.5 feet would be more absorptive at other frequencies than 80Hz, making your room more unbalanced. Stop me before I advise again! |

I also have about an 8-10db difference in level if the mic is held up at ear level (softer) or knee level (louder) when I'm back by the rear wall. |

one more question- i've found the info for calculating the depth etc. but no one mentions the dimensions of the box for either a Helmholtz or membrane resonator. what about length and width of the box? thanks again, David |
