Acoustic cloud question

[Chaotic]

I dont have a lot of room to work with. I know its best to hang a cloud from the ceiling rather then attaching it directly. So my question is:

What would be more effective, a 2 inch cloud hanging 4 inches from the ceiling or a 4 inch cloud hanging 2 inches from the ceiling??

[tomdarude]

4 inch cloud hanging 2 inches from the ceiling...

will help trap some more lows!

cheers tom

4 inch cloud with 2 inch gap would be better. But with that said a 2 inch panel with a 2 inch gap should be enough for the cloud.

yes you are right it will trap more low end, but don't foul yourself into thinking this will be enough bass trapping. You still need to work on the corner. Which I am sure you know this Tom, but wanted others to know it also.

The latter... gapping enhances low frequency performance, but is no substitue for the guts of beast.

If your room is small [less than 5,000 cubic feet or so - on the order of 20x25x10'] then you will benefit from the use of a broadband cloud - one that works on the LF compenents as well as mids and highs - unless your room contents already provide significant LF absorption and needs only early reflection control [not likely absent a fully absorptive ceiling which obviously aint the case].

If all you need is early reflection control, then you can forget gapping altogether and mount 2" panels as flush as is convenient.

I recently made a 4' x 4' x 2 inch mineral wool cloud for my studio. I used 2 1/2 inch wide moulding for the frame, and used black burlap to stretch around it.

Hung it with eye hooks and wire. 2 inch gap from ceiling.

Looks good, the middle of the room is tighter for sure.

I will never build anything like that again. Hung it myself, neighbors were all gone, or else they knew what I needed, and hid! HAHAHAHAHAHAHAH!

Buy them folks, it taint worth it!

BTW, after all the stuff was bought, I saved NO money.

Nah, I enjoy building things. Plus I do wind up saving a bunch of money. I pay about $7 for a sheet of 703, maybe $4 for the wood for each frame, another few dollars for the eyehooks, and use only a few dollars worth of fabric for each panel. So I will wind up saving a bunch of money.

Next I want to start building some SCA pre's and whatnot.

Bass trapping should be covered. Im putting 703 in all corners, and not just panels caddy-cornered, Im actually cutting each sheet of 703 into triangles and stacking them, so the corners are filled with 703. Also putting absorbers at first reflection points, and more 4" panels across the back wall (behind mix position).

Then I would just go with 2" on the ceiling. You really do not have to gap it if the other low end is covered, but I would just to make sure.

oooops.... glenn is right!
thx for pointing out...of course corners still need to be treated, there´s hardly too much basstrapping ever


ps: glenn,
is there a reason for thinner panels besides cost/handling/space etc.??
every surface-part you have, would benefit from a deeper low-cut in absorbtion anyway, right ?
pps: mailed you via the mail-form on your site, did you get that mail? was asking about shipping, etc.... cheers tom

Maybe,

But is your time worth nothing?

Caint bild dese in tin minnets sun!

FWIW, I am a tool man also..but I would just have it done. YMMV.........

Hey Tom,
IMO, No it is always better to use no less then 2" panels.
I have had a couple problems with our quote email. Would you mind emailing me direct at glenn.k@gikacoustics.com? Sorry about that.

Glenn

[tomdarude]

thx glenn, nevermind...
I´ll mail you again or maybe better give you a call in the next days/weeks...I´m busy renovating the new room.
I think we need to talk

cheers tom

[charleslee]

hope it's not too late to ask..

how about some pix of your DIY clouds? I need some ideas to treat my place.

Thanks!

Since this is lowend theory, how about big beach umbrellas? Seriously.

If you are trying to keep the sun off of you it will work great. If for acoustics then NO. It will not give you the high end absorption you really need.

Okkkkk. Tell that to Tom Dowd. Not trying to get into an argument, ok? It sounds like you haven't actually tried it. Don't diss it until you have tried it. Peace.

Just wanted to point out a gripe I have with my readyacoustics panels, in case anyone is about to buy some:

The straps on the back of either their 2" or 4" panels cause the panels to hang at @ 4" from the ceiling. I would have really liked it to be 2" so I don't have to build frames for them, and hang from the frames instead. Half the reason I bought the panels and panel bags was to avoid having to build frames for them. I might as well have made them all myself....

No way man, ITS ON NOW!!!!!!!! he he he
Thats cool, if you think it could work then maybe you are right. I have never tried it, but I would think you would get some strange reflections off it

[Acoustic Cloud]

Basic science says that wont work, I dont care what Tom says.

Peace

eh, yeah that seemed totally defensive on my part! You know, it is more of one of those guerilla recording techniques. It is just a sound, rather than some ideal acoustic treatment.
