treating a 16x14 room for mixing (Sketch)

Hello, I have a 16x14 room that will be used for mixing. I'm stuck with these dimensions but hey, it's rent free! There are standard acoustic ceiling tiles at 8 ft. with the actual ceiling ramping from 2 inches to 2.5 ft. - The floor is carpeted I am currently builing 4 inch thich 2x4 panels for the corners (2 each) I am also builing 2 inch thick 4x8 panels for the walls - The material is 0C703. I will be monitoring with very small powered monitors at low volumes. I would like to get the room flat as possible. Here is a (bad) room layout sketch - let me know your expert thoughts! Things like best monitor placement as well as panel placement would be great info! Also, I'm looking at covering the panels in muslin. It seems to allow less fiberglass to pass through compared to burlap. My girlfriend wants to dye the fabric for the 4x8 wall panels...hopefully it wont interfere with the acoustic properties!

There is an announcement at the top of the forum about what to do to assure getting as many responses as possible. The announcement leads to this post. Actually, several people, who are experts on this forum, will not reply if you do not do what is written in the post.

thanks I was able to upload the sketch. hopefully someone will have some feedback on treating this room. I'm curious how the ramped ceiling will change things. By the way, sound proofing is not a concern here. this room is but one in an old church from the 1800's. here is a photo with mp3s at the bottom: http://benlongmusic.com/Church

right...I see...is that church in Arizona or is that a secret as well?

nope, Denver - two blocks from my house. here's a partial sanctuary shot. I have no shots of the mix room though (if I did, it would bore you to tears) - It's part of the modern annex to the church and very average compared to this main space down the hall! hopefully I can turn it into something decent

Things I am interested in will never bore me to tears ;)

wow. 145 views and zero responses.... this is amazing :shock:

Actually it is about par. It is up to you to help, that stick sketch doesn't give any kind of an idea as to what this room is/has/wants/etc. "Here is a (bad) room layout sketch - let me know your expert thoughts! " /quote What can an onlooker do with this statement? It reads to me like you are moving in a direction, you got information from somewhere and it seems correct as these things go. I think the main confusion, for me a professional carpenter but not an expert acoustician, is that I can not ascertain if you are in the stick sketch or the historical building? Is it mortar you are working with...or air? Sheetrock walls...or sticks? ;) I can't speak for anyone else but I am not a mind reader...so I wouldn't know what to say to help you. Well, maybe a few things, but not much. Anyway, did you read this page: http://www.johnlsayers.com/phpBB2/viewtopic.php?t=3231 ...it really is a helpful page that applies to many other websites of this kind but particularly this one. Bruce Swedien was here a few months ago, dropped in to share the love, so this place is "all that" ;) Good luck

well, I already mentioned that the mix room is in a modern annex attached to the historic part via a long hallway. It has nothing to do with it other than being down the hallway. I will add that the two side walls long ways are painted cinderblock and the others are sheetrock. other than this, there is no more information needed! The mix room cannot be "rebuilt" so I am going to "treat" it so I can "work" in there. What I am looking for is expert advice on dealing with the ramped ceiling and the best position for me, the speakers, and the panels. It really is that simple. The 150 lurker views is what astounds me

The experts told me: If you have a vaulted ceiling have the higher part at the back of the room. Speakers should be approx at a position 38% of the total distance from the front wall to the rear wall. The 38% is too keep you and your ears from being at 50%, so that is your starting position..not a hard and fast placement. Speakers should also be at a position to NOT be in the center of the distance from floor to ceiling height. Speakers should also be in an equilateral triangle with your head inside the third angle. Bass traps do wonders for acute angles so the one at your back would gain aid by having them. Panels should be placed in a RFZ configuration(look it up). It is all in this website..the 150 lurkers are astounded that you have no drive to get this free and wonderful stuff at no charge to you

What is behind the ceiling tiles? The amount of space affects the low frequency isolation. That is just one example of "more information needed." XSpace has already posted about what can be suggested with the information you have provided Andre

there is nothing above the ceiling tiles.....just space. The actual ceiling ramps from 2 inches to 2.5 ft.
