Dave Moulton designed room

Hey guys,

I am brand new to this forum, but not to the world of recording. I have a design philosophy question. I have read several articles by a man named Dave Moulton who makes certain acoustic design claims that are counter to commonly accepted wisdom.

1. Front wall should absorb all frequencies (from high to low)

2. Ceiling above mix position should absorb at least mids and highs

3. The side walls should be reflective at all frequencies.

4. The back wall should be diffused

It is his claim that this design will address the issues of bass standing waves, reverb decay time, etc.

My question...is there anyone out there (perhaps John) who has good reasons why this design is not all that good?
 
That's pretty close to the kind of Control Room John designed for me...!
 
well yes and no Bruce :)

I don't agree with Dave's room design at all. It's called LEDE (live end dead end) and came into fashion in the early eighties. I don't think you'll find many of them still around today because they did not work.

I won't go into why I disagree because it's a long long post and I'm tired from all the war talk :)

cheers
John

Yeah... I know, John! ;)


Just to elaborate - I said "pretty close" thinking of the following similarities (as I saw them - and I'm no expert!):

1. Front wall is absorptive/diffuse

2. Ceiling above will be fitted with absorptive panels

4. The back wall is diffused via slot resignators

Well this is a pickle... Two highly respected and recognized people with vastly different opinions. And then there's me...I don't know anything that one of the experts hasn't told me.

Sigh.
 
it looks like from your post that only (3) is different so it's not so bad.
What seems to be in fashion now is to mix the side walls with both absorptive/diffuse areas.

but I could be wrong also :(
 
Usually when I have a problem trying to decide what to do, I just do it both ways and let my ears decide (do I want hall or plate on that vocal?) However, in this case, I don't have the luxury of building two studios to see which one works best for me. In the end, it may have to be a leap of faith.

I would like to hear from people who have worked in different environments. I am most concerned with translation of mixes to other environments (aren't we all?) and the ease and comfort of working.

Does anyone have any observations about the rooms where you enjoyed these two luxuries?

Thanks
 
Why not...

.... build variables. Front, sidewalls, ceiling. All with quadradic or fractal louvers.
Variably open/closed. With the rear ones, when closed, gapped for slot absorbers. Maybe with some of them with quadratics or primitives behind, along with portions of absorption areas. Arched clouds, on variable pivot, diameter and centerpoints, when moved open the ceiling to large bass traps. Lots of edge effect when exposed absorption areas are open. Even the floor. Use a steel walking grid over 4" 703. Large hinged panel reflectors that also act as membrane absorbers.......and 240v neutron reflection phase inverters with time aligned and coherency corrected diffusion beams, all enclosed in a -10 log db photon enhanced outer shell thats floated with 1hz laser guided airsprings, mounted in plasma goo isolators that is.....ah....oh.,,:o :o :o heheheh,...... excuse me, got carried away:D Fun dreaming though.
fitz:p
 
Fool - EVERYBODY knows that neutron reflection phase inverters will arc across at 193.497 volts, unless implemented in a .0001 micron or better vacuum, in which case no sound (in space, they can't hear you scream)

But keep trying, Fitz - remember, even vulcanized rubber was discovered by accident :=) Steve
 
Damn Steve, I knew if I snuk outa class that day, I'd get caught sooner or later. I should of known it WOULD be by YOU!!!!;)
fitz:D
PS, congrats on your moderators spot at Johns site.
 
That is truly hysterical...really, really funny.

I still wouldn't mind an actual answer to the question however. I am just interested in the basic charateristics of the control rooms that are being used by people out there and whether you are happy with them. Thanks.
 
I have never been fond of LEDE rooms, particularly in control rooms.

I was under the impression that Dave Moulton was pushing a "Non-Environment" sort of room, using specially designed wide horizontal dispersion speakers, and NOT LEDE at all... Steve

BTW, I've not heard anything in a room like this so can't comment at all on sound -
 
That's right...Dave Moulton was specific that the speakers have a wide dispersion.
