I have read this before about rockwool 6-8 inches, is really about it.

I'm just about to make the purchase of more OC703. My front wall has a lot of broadband 703 absorption, but I have a new idea. I'm going to make the front wall 12" thick. It will be:
4" OC703
2" air spacer
4" OC703
2" air spacer
Wall
From my reading, you get extra benefit from an airspace as long as it is not more than equal to the thickness of the absorption. In my case it would be only half. Yes, I could make the 730 solid for 12" but I'm not sure if I gain anything. I watched all of Eric Valentines videos. I know he got his room responding as he wanted. I'm not completely convinced the Tube Traps were any better than using OC703. It's basically the same thing. Does it really make a difference that it is round instead of a flat penel? I'm not sure. The OC703 lowers the velocity of sound waves, drom what I understand. Having a foot thick wall of it may be even better than Tube Traps. My room at the mix position works well but I still have a couple issues 100hz and down. I think this might solve it. Next, I'd need to figure out a clever way to make the panels. I've basically used the GIK design for some panels in the studio, along with some real GIK panels. That's fine for 4" thick, but once I get to 12", I think I need a better design, so they stack well and easy.

I just placed the order with ATS for another 24 panels of 4" thick OC703. The front wall will now be solid OC703, 12" deep plus an air gap behind it and maybe I will place a spacer between panels. This way I will end up with 15" deep panels. If it smooths out the low end just a little more, I will be happy.

You’d get better absorption with 4 inches of GFR 5,000 material in front of 8 inches of 703 versus 12 inches of 703. I went with Caruso isobond to do this very thing and they’re sold in the same size panels as 703. The attached picture shows the difference Attachments:

a buddy is lending me eight 9" ASC traps, and I got to try them around a drum kit today for the first time. holy cow. tighter low end (by a LOT), and a way clearer left-right image, plus an improved sense of general depth with less weird resonant ringiness. All without changing the general character of my live room. pretty darn cool.

They are, I still maintain the secret sauce is the fact that in one plane you get the same characteristics in every direction, still think someone needs to build a ball. |

Would there be enough volume inside a ball to offer the control that a tube does? Seems to me that the tube's efficacy in the horizontal plane comes at least in part from the volume offered by its vertical dimension? |

I’ve been wondering about how much difference that would make for drums or other acoustic instruments where performers are seated. |

I’ve been wondering about how much difference that would make for drums or other acoustic instruments where performers are seated. They are on the stands they come with, and I'd say they are about five feet high. Maybe a smidge less. The tubes themselves are 4 ft, and the bass is probably like 6-10 inches. When you position them around a source, they create this sort of 'forcefield' that you can hear as you enter it. It extends a few feet outside their circumference, and then of course once inside the perimeter it's quite easy to hear. But it has this clarifying effect that sort of feels like a more dead / dry room in the near field, without 'muting' the further-field reflection and ambient action. It's very cool and makes cleaning up spot-mic'd sources very easy. |

Hey I didn’t say it was a perfect theory 😁 Yes they would have to be pretty big, but who wouldn’t want to say “ yeah I have big balls”? It would just be interesting to see if the idea of equal absorption was perceived as better or not. |

Not sure how different they are based on the tube shape vs the same amount of 703 in a standard panel, but I do have four 10" x 2" 703 pipe insulation tubes on my front wall and what's nice is that they're free standing, light weight and stackable. I may fill them with insulation at some point, just to see.

I got two of the larger ones in a good eBay deal a few months ago. They are awesome. Stuck one in an untreated corner and could immediately hear the difference. The other one moves around depending where I need it. They’re pricey but I’m going to try and collect one or two here and there as they pop up locally.

I don't know why, but for some reason I was under the impression that they can be raised or lowered on the stand that they come with. No idea why I thought that... |

They can indeed be raised and lowered on the included stands. There's a little plastic clutch at the base, they go up to like 6.5-7' tall when fully extended |

Btw, GIK is now making tube style traps as well at a much nicer price. Not sure how they compare, but I’ve always loved GIK products.

I have 16 of the 16" diameter traps mounted on my ceiling and I must say that it allowed me to transform my mix room from a disaster to a lovely space to work. The ability to dial in the tone of the space by rotating the traps is one of the best parts of the design. |

at $16-1700 usd for just two, they better be damn good : enjoy ! I know, late to the party but Holy sheeeeit! I know another producer in town who has them, always thought they were cool but had no idea they were that expensive! Thinking most people have what…4 on each side, 4 on the back plus two monitor ones, then some have a few spaced behind the listening position…that is a lot of moola! |

I think the 10K (CAD) I’m gonna spend on a pair of RS660’s will be wayyyyy better for my room  . Damn, the list just keeps getting longer…no end in sight! |
