I used a pegboard and foam ice cream sandwich as the barrier between the chambers, the foam was lightly compressed.
Interesting I'd have thought the pegboard might resonate, though I suppose compressing the foam could pre-load and damp the panels. Guessing open cell type foam in the 1/2"-1" thick range?

I think it was half or 3/4 thick, and yes, open-cell.
