hi everyone. tomorrow i'm building a cloud to be hung over the mix position, several broadband absorbers to be wall mount and at least two corners with superchunk basstraps. as we cannot get 703 in germany, i found the following product as substitute. could you please confirm that i chose a product with the right acoustic properties? heres what i want to use: Rockwool Termarock 40 1000mm x 625mm x 40mm Density: 40 kg/m3 Flow Resistivity: 12 kg*s/m2

if you like to read further what i'm planning, heres the link to my thread in studio design: viewtopic.php?f=1&t=13210 thank you for your answer(s) simon
Seems fine to me!
hello ro. thanks a lot for your answer! i'm building the cloud tomorrow, so a fast answer was needed before i buy the wrong stuff... :roll: cheers simon
simon - before you add the cloth finish to the cloud make sure you wrap it in plastic otherwise every morning you will have a micro fine layer of dust on all your gear and console caused by the rockwool shedding and getting through the weave in the fabric.
thanks for the reply! i read about that problem in this forum (probably one of your posts) and bought a fleece for that purpose. but probably i should use some really thin plastic foil too... should i angle the cloud than because of the (high frequency) reflections caused by the plastic? thanxs a lot simon
you'll find the cloth stops too much high freq reflection.
