Fabric for bass traps and ...

[C/G]

Here is a question for you guys. I want to cover my absorbers (when I build them) with Fender silver face style grillcloth. This should be ok I would assume since it is technically made for sound to pass through.

The simple answer is yes. This "should" work. However, I am not familiar with it's application in a reverse role. Meaning; that I do not know how well it holds material fibers since it is designed to be very porous. This something to consider when choosing fabric for acoustic purposes as you do not want loose fibers to escape and fill your room.


Good Luck,

Thos stands are really out of the question for me. a. Cos I dont have the space and b. cos I live in Australia (shipping would murder me)

There needs to be some sort of way for me to attach hooks to the panels in order to hang them (with spacing) like a picture frame.

I think I get what you're after.. so how about a diy version of these:

It's basically whatever thickness of rigid insulation you want, wrapped in whatever fabric you want, with grommets at the top to hang it on a wall or suspend it from a ceiling.

I never thought about that. Maybe a layer of cheese cloth type material under the Fender grill cloth. I just keep thinking it would look so much cooler than the standard coloured fabric.

[Joel DuBay]

Yes, cheese cloth would likely capture any strays.

That is a really good idea I think. I would love to see those panels with a "Fender" logo on them! How cool would that be?

The ceiling may be a bit more tricky (that whole gravity thing...) I used simple oak trim piece over the ceiling pieces to add the extra support. The wall and corner pieces are mounted either directly onto the walls or spaced out with air gaps with "furring strips" generally 2 inch by 2 inch pine wood. This has worked well for me, and once I got the room tuned right, the panels never need to be moved.

Way to go sir.. One thing (which I think you are fine but let me point this out) Having a open air gap is better because sound can come in from the open side, bounce off the wall and hit the back of the panel.. Not that what you did was wrong but that is part of the reason to space the panel off the wall and why it picks up more HF sound..
Great job though sir!

The fabric will make a very small difference, but it's still basically cosmetic. Just don't go too thick or too airtight.

[QUOTE=Joel DuBay]Agreed, how ever, the membrane should need to "move" to some degree to ad low frequency absorption. If it does not, it will not. Painting an "open" cell foam, effectively "closes" the cell and helps to almost no extent.

Vote #2 ... I believe speaker grill cloth is polyester

Can I use crown Royal bags ??? LOL

I have a feeling it will be really expensive but it will look totally boss and once ambient lighting reflects off the silver in the cloth, it will be cool for a nice mood in there. I thought about Hiwatt style salt & pepper cloth, but the silver and blue Fender style would be the coolest.

Dee,

> a sine wave is at maximum velocity [at] it's 0 crossing, and minimum velocity at 1/4 wavelength <

Yes, but what Kiwi said is also correct. What our ears respond to is wave pressure, not velocity.

To use your electrical analogy, a device draws the most current - and thus power - at the input voltage peaks. So where the voltage is highest, the most work is being done. Even though the velocity happens to be lowest at that peak.

--Ethan

Yeah, I'm just being a geek. I always liked the pendulum analogy. When the pendulum is furthest from it's resting state. It's velocity is 0, because it has to stop and turn around and go the other direction. Same with all periodic motion. Not that any of this really matters in any practical situation.

Ok, that's the greatest idea I've heard yet. Why not? Grill cloth. You gotta show pics when you're finished Colin

p.s. I just thought that this would be a typical guitar players response.....

[AlexLakis]

I used burlap on the walls and ceiling, and that outdoor gardening cover stuff in the corners. Light blue with a black stripe on the corners all covering 703 and 705. Looks nice. Works just great. Just don't light a match...

Probably won't happen until next summer because we are in a temporary space right now, but I might build a few anyway. I am now thinking of wrapping the wood frames in black tolex. Could be more trouble than it is worth but it would look cool. Depending on room colour, maybe an oxblood grill cloth with beige tolex on the frames would look nice too. I'm going to stick with the silver stuff though.

I've got some micro-suede .... would that work ???

I went to the same placethumbsup

I made some hanging overhead clouds and a bunch of side/corner panels with large custom cut pieces of OC 705[My brother in law is a contractor] wrapped in the Guilford fabric.
The clouds hang on picture wire with small hooks and custom clear plexi washers.
I mounted the corner panels with long thin finishing nails..easy to remove if needed.
The fabric is very transparent sounding..works like a charm and looks great.

I also made six more standard sized 4" 705 2x4' corner traps with Joel's Readybags .
They have the suede vibe,look great..easy to assemble and hang..

So far ..I've spent around 750 bucks..well under my intended budget.

My room sounds very tight and focused, but not remotely dead
