As I remember it... a space behind equal to or a little greater than the depth of the panel acts as a trap. It doubles the effective thickness of the panel. Any farther away from the wall and the panel allows the waves to reflect back into the room.

Placing the panels on the wall like pictures will cause them to absorb the higher frequencies and reduce the slap-back and reverb of higher frequencies.
Putting space behind them improves their ability to reduce problems with lower frequencies Gets rid of the "muddy sounds' Young guys in radio 30 and 40 years ago loved studios where the walls and ceiling were covered by those peg-board looking Celotex tiles. They were purposely pitching their voices as low as possible because that was the way the stars of the era performed. They loved working up close to the mic for the same reason.
If you work very, very close to your mic, putting space between your panels and the wall may not be as critical. BUT: What about the LISTENING process? I built my room to be a good monitoring/listening/mixdown space. (Music producers seem to put much more emphasis on their control room /listening area / monitoring location than they do on their recording space.
V-O folks using the small booths for recording need to consider their listening space also. |

Good info.
Based upon that...I think I will start out with them flush against the wall and then progressively see about moving some...or all out from the wall. Possible with an arrangement similiar to yours. Although how you got the nail and the hole in the dowel to math up...seems like something of a challenge. |

In those days...when you are 20 years old and doing midnight-6am...and the Morning Jock sounds like the "Voice of God" then...you need all the help he can get.  |

I drove the nail into the wall-bracket
removed the hail-head with wire side-cutters
mounted the bracket on the wall
put the panel up as though I were mounting it
and let the nails put marks on the bottom of the stand-off
took the panel down and drilled where the marks were.
It's kind of farm-boy grade of woodworking
but that's o.k.
How many other people (besides me) will ever see it? |

That's some impressive work. I'm going to have to plug some windows as well. I live on a dead end road halfway up a mountain. Very little traffic. BUT...if one of my neighbors isn't mowing or blowing his grass...it's probably not daylight.
(sigh)
And...where does one find "recycled denim?" |

| HOWEVER....I believe they stopped carrying it in single bundles. At least, my local one did, and they don't have it online anymore individually. YMMV, and you might be lucky though. |

| Can't go wrong with a favorite. OC 703/705 has been a staple for a long time, even in home theatre circles. |

I wanted to use the OC product because it is "the common denominator" but I couldn't find a place to buy it. I still hope to locate some just to get a feel of how it handles during construction compared to the other products.
I assume there has to be some place in Atlanta that sells it... but they keep themselves secret.  |
