Cloth question...

Seems some will say almost anything will do, while others stress the importance of open weave for covering bass traps...

I have some material that Id like to use. It is not unlike bed sheet material except much thinner, you can see the shadow of your hand through it. You CAN blow through it if you have your mouth right on it and blow very hard.

Now, I am pretty sure that it would be ok to cover the bass traps in this stuff, yes???

I am worried about my first RFZ panels though, I want to make sure this material will not affect the absorbtion of mids and highs! What do you think? Like I said, on a search I did on this forum I came up with a number of conflicting ideas. Thanks! :0)

Anyone ??

I think that open weaves should be more efficient to let those frequencies going thru the fabric but tight weaves dont interfere for low frequencies absortion.

Hi Serge,

Thanks alot for the reply. I feared this to be the case. Isnt it funny when you have something lying around that may seem useful for a job at hand, it turns out its not suitable!!!

I had hoped that highs/mids would be able to get through thin material, even though you cant actually see holes in it, a strong blow of air will make it through. Oh well

I did a job recently with OC703 2" with frames covered with thin weaves fabrics. This was called Spandex, you know fabrics that are used for wearing skaters, gymnasts in artistic comprtitions. This fabric breathes, is highly strechable, witch may help to cover the module. The result was quite good, maybe not the most efficient fabric(absorbing mids and highs) but it did quite good for absorbing lows/mids/highs. Experimentation is maybe the way to do it and less costly if you do it by yourself. The worst that may happen is you will have to change the fabrics. You could try one sample and "hear" the results.

Happy tweakenings

Thanx Serge,

Dont know about experimenting, its alot of work to cover some panels, unstaple it all, and then try some thing else

I may try the cloth I have for all the traps except the ones for first reflections on the side walls. I have a foam section on the roof between me and the speakers as well as carpet on the floor. So hopefully, even with the type of cloth on my traps, I will have enough mid/high absorbtion, hopefully!

You still can put fewer staples, just enough to hold the fabric/insulation in place then hang it. Test it in place and clap you hands, talk in front of it to hear how much absorption, direct at som angle one monitor with pink noise, then test with/witout the module. You should at least hear differences in the range you want to absorb.

I decided to go with the cloth that I have. I compared it to the material on a pop filter, and in terms of blowing through it, they are much the same. So I figure it wont bebouncing back much mids and highs....I Hope

Yep, as long as you can blow through it, it will be fine
