Flush Mount Corner Bass Traps

GTV630 · 14th February 2008, 02:44 PM

Hello all. I am new to this forum, but have been reading much on studio construction - thanks for all the great information. I am planning a small one room home studio and have a question about building bass traps. I would prefer to build them to mount flush to the corner walls for appearance. I have not seen any designs like this posted on this forum. I have modeled two different designs and would like feedback on them. I will be using 24x48 mineral wool panels (total of 4 inches thick), and covering the frame with material.

Design one is basically a 24x48 ID frame that has extensions that take it flush to the walls. The gap formed by the angles could be filled with standard batt insulation. I will post design idea two in the next message

In design two, I have tried to reduce the amount of floor space occupied by the corner bass traps. In this design, the max ID of the frame is 24 inches wide. This means the mineral wool material must be cut to fit in the shape. In the attached pics, I have shown the mineral wool with straight perpendicular cuts. Not having worked with this material before, I don't know if it is possible to cut it at a 45 deg angle to match up with the frame. While this design will save considerable space, my question is: how will it effect the performance of the bass trap? Reducing the width of the bass trap also moves it closer to the corner (reducing the air gap behind the trap). Does anyone see a problem with this design? Thanks.

Can you let us know the specific dimensions of your room, and maybe what kind of monitors you're using? Do you have a sub? Either way, that should help establish an idea of what sort of treatment to reccommend.

I found this thread to be really useful:
How I built my bass traps...

Why not just fill the whole corner and place fabric on the front? What you are thinking of building will work but just filling the whole corner will look just about the same work much better.

Let me try to clarify the reason for how the pics above were designed. Design one is based on using 24" wide mineral wool panels. Here I basically took the same design others were using (a rectangular frame). but extended it to mate up flush with the walls. I mentioned before I would try to fill the gaps with insulation of some sort, but the mineral wool panel would not be wide enough to extend all the way to the wall.

Design two starts out at a 24" width but due to the taper of the frame, it narrows. I would try to keep it stuffed with the mineral wool as best I can, but I don't know how well I can cut this material at a 45 deg angle, so I showed worst case, using straight cuts. The nice part about design two is that it saves space in the room as it is closer to the corner. However, my biggest concern was a slight loss in total mineral wool volume, and less air space behind the trap. Attached is a pic showing some dimensional differences. Sounds like you are saying the changes will not effect bass absorption enough to be concerned with, so I will plan to use design two.

Thanks,
