OK, this may be a stupid idea, but any who ... just wondering if any one has researched this idea.
I was thinking about using Louvered doors to build an absorber/diffuser/slot resonator type things
Basically, build a frame using 2x4's, fill it with OC703 or Roxul insulation, cover it with cloth and then use Louvered door in the front of the frame. What do you think? I know you need to use certain measurements for slots and slats for resonators, but this may be a good way to get by without too much work. I am not sure what frequencies it will absorb though.
Using a 2x4 frame on edge, and assuming 1/4" slots between 1/4" x 1" slats, it works out to a center frequency of around 1 kHz - increasing depth to 2x6 (5.5") lowers it to 750 hZ... Steve
It might work - however, there is a difference in layout between a straight slat resonator and louver doors, so you would get different results. Likely a bit more diffusion, and probably less predictable frequency centers. Also, you'd need to improve on the louver doors I've seen to keep them from having massive rattle problems... Steve
