Are these any good for absorbtion?

http://www.atsurfaces.com/index.htm I just finished my room and I need to treat it. This company is not far from me and their prices are good. I just want to make sure these are good panels. My room is 11'x11'x8 and is used for dance music. Everything is going to be done in this room production to mixing. Thanks, Anthony

The materials may be okay, but all they offer is one- and two-inch thick panels. This is nowhere near good enough for bass trapping. And a small square room like yours needs serious bass trapping. --Ethan

Thanks for the reply. My concern was the material. I see everyone using corning 703.I spoke to someone there and they said they can do 4" thick. How big should the traps be? Also,do you suggest diffusion on the rear wall and ceiling? Thanks again, Anthony

Hi Anthony, You may want to search for bass traps on the site. Also, check out some of the design in "Other Builds". Especially Lou's from page 20 out. Lots of pics there and would give you another perspective on trapping. W

Ethan you mentioned I would need major bass trapping in my 11x11x8 room. My question is how tall should the traps be in the corners and do I need them where the walls meet the ceiling? I have always had a problem when it came to mixing my stuff so I want to get this right. Thanks, Anthony

your room dimensions as it appears are very bad if you can manage to place trapping across all your room corners (ceiling walls; walls floor; walls walls..) there are lot of info here in the forum lot lot lot :yahoo: spend some time searching

How big should the traps be? Also,do you suggest diffusion on the rear wall and ceiling?

BIG!!! You have a square room, which is bad to start with. As Ethan said, you are going to need heavy bass trapping in there. Perhaps "Superchunk" traps in all four of your wall/wall corners, floor to ceiling, would be a good start. Plus whatever other corners you can get them into. Ceiling cloud, more on the walls... Take a close look at Ethan´s web site: he has a stack of very useful information there on bass traps. - Stuart -

As tall as possible, and Yes. :mrgreen: The more total corner surface you cover, the better. Always. And remember that most rooms have 12 corners. --Ethan

First off... thanks for all the advice. I try to read as much as I can about all this stuff to have a better understanding. Anyway, so I got the panels over the weekend and install all the wall panels. I ran out of clips so i couldn't do the ceiling yet. Just as a test I took the ceiling panels and put them in the bottom half of the corners. What a difference when you are sitting in the mix position. The bass seems more even and much smoother....when you stand up it's a different story. These panels are only 18" wide,4' tall and 2" thick so I was thinking about using 18"wide x 8' tall (2x 4' on top of one another) x4"thick panels in the corners. I was going to build superchunks but I am tight on space as it is. Any thoughts? Thanks again!

you can always stack 2 pieces of wool together to get more volume ofcourse (taken that it's unfaced wool) A corner panel can take up as much space as the "superchunk", the latter just eats up more wool to fill the WHOLE corner. Is that better? well, there's been discussion about that. It sure is a bit more expensive (need more wool). I'm a big suppachunk fan m'self :) (big trap, lotsa volume and easy to build)

Well I'm kind out of money plus the panels would not be as wide as the superchunks. I have friends that have no bass trapping just panels on the walls, ceiling and use IK Multimedia's ARC system. They are having much success with their mixes translating in a night club. I know some people are not fans of the ARC system but I have seen it in action. I actually didn't believe it until I sat down in a friends studio and listened to songs I know well. The studio I was in has major bass problems also and the plugin corrected it. When listening to a song I knew sounded good in the club without the plugin enabled the bottom end was very boomy. With the plugin enabled the mix sounded right. Anyway I'm looking to get my room as close as possible and I will let the ARC system do the rest. Thanks again everyone for all the help. On a side note the guy I got the panels from does nice work and is very reasonable.

...and the plugin corrected it

Sorry to be so blunt, but no it did not. It did not because it cannot. (marketing hype aside). It is an equalizer. A fancy one, yes, activated by an RTA, but still an equalizer. Therefore it CANNOT correct reflections, reverb, resonance, modes, and other issues that are related to the room, no matter what the sales pitch says. Unless it can suck sound back out of the room after it starts bouncing around too much (and do so selectively in both space and time, accurate to 1 Hz!!!) then there is nothing at all it can do about those issues. All it can do is disguise some of the issues superficially. It only corrects frequency-domain issues, so if the sound improved when you turned on the plugin, then most likely there where existing serious EQ issues with the rest of the system (speakers, amps, interfaces, whatever). All it did was to fix system issues, not room issues. If a cheap little EQ plugin really could do what it claims to do, do you really think smart audio people all around the world would carry on spending big bucks to build and treat studios? - Stuart -

[/quote] Sorry to be so blunt, but no it did not. It did not because it cannot. (marketing hype aside). I/quote] The room I was in was treated for reflection but had no bass trapping. So I guess It EQed the bass the way it should be. All is I know is I heard what I heard.

the plug only worked IN THAT ROOM. Taking out your low-end-plugged mix to another room proofs the plug is useless there.... THAT's why we call it a "transparent" mix. It works in ALL rooms (good and/or bad)... (well, sorta) It's mistake no.1 to EQ a mix to fit the room... it should be the other way; EQ the room to get a good mix.

You could give out a free plugin(at cost to you) to everyone that purchases your music!
