I've got a 12x22 ish room...I have a small area in the front of the room that I've deadened/isolated nicely for a vocal booth - happy with that. But at my listening position, in the back part, it's still pretty lively. Still flutterish. Do you think it would better to put an absorptive cloud above my head (listening position) or should I put bass traps all across the wall behind the monitors? I have six inch bass traps in all the corners. My inclination is to put up some sort of cloud. Would a pic help?

The obvious answer is both! But with flutter you might need some mid band absorb toon on the side walls first

I've got auralex wedges on the walls...I'll try and get a pic up.

Absorption at all first reflection points, wherever they are...back front above.... Bass traps in all the corners you can manage.. I have them at wall ceiling and wall floor where I was able.
Cheers

bass traps work better if they run into each right angle wall not bisect
you know the mirror trick ? from your monitoring position have a buddy slide a mirror on the adjacent walls and ceiling, where you can see your monitors, place absorbers.
I built a cloud too and do think it helps
if you leave space behind your absorbers it extends the bass freq absorption.

I was told by a dealer of the stuff that leaving a space behind doesn't make much of a difference until you get to 4" of absorbing material in the panel. I'm trying to figure out if he's feeding me a load because the panels have wood backs and I questioned the efficiency of that design.
I'm in the process of putting together my room from scratch right now. I have a somewhat unique room with a combination of flat ceilings, 45 degree wall/ceilings, and 4' walls going lengthwise. I'm putting 2x4' x 4" panels in the corners (OC703) and I'm considering going with2x4' x 2" panels at reflection points = above, l/r, and behind the desk.

From my experience super chunks in the corner are better then panels.

cool room! that ceiling shape and it's lowness are a little tough to deal with, i'd get the entire front listening area absorbing, the stuff behind you will be far enough away from the monitors for your ear/brain to separate the reflections from the source, i'm a big fan of absorbing directly above my head on low ceilings, also a nice piece of 4x4 plywood on the floor in your cutting area will give some good early reflections as long as the ceiling is out of play by absorbing it, and should add Q to your vox/acoustic parts.

There looks to be a reflection point right about where that ASCAP panel is - and on the other side as well.

So Tony, you're saying put absorption on that front wall and then a cloud above me? I have a cloud in the back singing area - seems to work really well there. I thought about getting a one inch plywood 6'x6' and putting some hardwood on it...at least it would look cool.

You can get an 8x4 sheet of 1/8" tempered hardboard panel at lows for $9 and make a few moveable panels out of it, it's totally light, strong enough to walk or put a chair on, and moveable, they work very well, and have 2 different textures top and bottom. heres a superchunk in my room, i have 2 of these, it's 36" across the front and i used ultratouch cotton insulation behind it, had a great + effect on the room.  |

superchunks, are triangles of fibreglass stacked on top of each other floor to ceiling in the corner of your room.

That's what I'm thinking.. probably doesn't make much difference in the mid-highs, but I'll bet it makes a pretty big difference below 1200hz or thereish. Anyway you slice it, it's a direct reflection, right? |

Unlike most of these folks, having spent time in your room, I know what it sounds like. The number one thing I would recommend is a ceiling diffusor running about 4' wide and 6 - 8 feet long. As close to the apex of the ceiling as you can get it. You already have enough absorption. a couch/love seat in front of the baffles for your vocal area would also help with flutter.

Yeah  Not fair.. No doubt overhead is the closer and more significant reflection point. And yes, for those of us who haven't been there, it's hard to imagine how live the room is. I'll be posting pics of my set up shortly.. Still working on the room - putting finishing touches on the floor and picking fabric for the traps and such.. (my wife is the lead consultant for this delicate part of the project.) Damn, it's just a home studio! |

Cool...yes the super chunk tamed most of my low freq issues. I used 4" mineral wool panels cut (4 triangles per board) stacked from floor to ceiling leaving a small space in the very corner with fabric cover frame. I had 4" acoustical panels strapped to the corner and it wasn't near as effective. Johnkenn definitely put some panels on the front wall. It's easy to test your setup by sweeping a sine wave and listening to the dips and peaks of your listening area. |

If you super chunk behind some pre-built panels - you have enclose the fiberglass, right? That's a lot of fabric.

hey JK, here is what I did for early reflections; built 3 equal sized panels; 2 on either side and one as cloud from monitoring positions and you can see my corner absorbers too the frames are made from rigid insulation I glued and screwed together and used small L brackets a diffuser is a bit more work but a good idea especially in a small room my room is about 11x20 x7-8 feet back wall has a floor to ceiling 4 inch absorber and I mounted hanging brackets so I can hang one of my 4x8 absorbers as a cloud when I am tracking in the back, I kept my mattresses up that I used for the drum tracking too.
