If you don't get raised eyebrows, you haven't gone far enough! :grin:
@ Sheggs - that is a surprising comment, it was my understanding that the higher density rock wool was significantly more effective at lower frequencies (i.e. higher absorption coefficient at frequencies below 250Hz) that the lighter loft style installation?
You guys at GIK are the experts on this, so I'd welcome your clarification on this?
It depends on what type of trap you are building or using -
If you are using a panel straddling the corner then the higher density will be effective but with a corner trap style it is the distance from the front to the back corner which is important so filling the area is more important. We always suggest you make them big. Generally speaking tests have shown when dealing with corners that there is not a lot of difference in the results between the densities, the fluffier stuff is just cheaper
Thanks again sheggs. My original ideas are tricky to implement due to the nature of the RS60. Current thinking is a solid triangular prism with a front freestanding baffle to make it look ok. Already finding subjective comparisons difficult so I recon this project is going a bit longer term! On the wall behind the setee I am experimenting with a 4'' panel resting on the setee rather than a permanent fixture. This angles upwards which doesnt seem right but I will keep going.

I saw a desing very similar just recently.
A 4" inch thick panel straddled in the corner (you need to make sure that it is actually touching both sides of the wall) has been orven to be very effective at 60hz. The corner trap wil tackle even lower though. we recommend using a 4" inch panel for corners if not going for a superchunk. The RS60 will be ideal for this
O dear! Now I wonder if my solid triangles will be less effwctive than a panel maybe 4''. The triangle is less than ideal at 12x12x16'' and 20'' tall. I guess if I cut the back of the triangle then I get a panel. Mmmm.
Maybe I've been misunderstood here, a panel is not more effective just an alternative if you haven't the space / money they are cheaper and are quite effective I have also seen several designs recently that has a panel front and the triangle behind. What you are doing sounds great
I would always recommend a superchunk style first
Very grateful for your expert opinion. Kind Regards.
Cowboys and Aliens just gave my system a thourough workout. Sounded brilliant. I'll post some pics when I get the cloth fronts fixed but I am really delighted so far with my days work ! Went for a corner trap and panel/baffle front (2" RS60) in the end and it is working out well.
Look forward to seeing the pictures
