I don't know, but the insulation and its position are pretty important. For example, if you don't span the cross-section with a sheet placed on the brace between the woofer and tweeter, you'll notice a blip in the lower midrange. So don't experiment with the insulation unless you know it is equivalent or you have some measurement gear to check it out.
