I think Rod Gervais answered to this already, but as I've understood it, placing boards in front of, say, a superchunk is just essentially making the room more reflective. The gaps between the boards are for controlling the amount of absorption vs. reflection, correct?
And these are not the same as a proper Helmholtz-resonator or the like (unless of course built as one).
I've sometimes seen the spacing between the boards being varied as well as the board widths, is this more for aesthetics or, as I'm guessing, there is some acoustic reasoning behind it? (Helmholtzes?) |
You're assumption that placing boards in front of something like a Superchunk is purely for absorption is incorrect.
Eric Desart's
thread at John Sayers is rather enlightening...
But the essential takeaway, is that the width of the board, the thickness of the board, the distance of the spacing between boards and the depth of the cavity, are by definition, acting in concert as a Helmholtz Resonator.
Hope this helps clarify...
