No it is not bad. Actually it is probably near the maximum (others would misrepresent as optimum) depth for low end absorption and flat absorption response
with that particular material's charcteristics. Paul wrote it right in the post previus to yours. For more information start at post 23 in
this thread. If you want to get into the deep end read this thread:

There is nothing magic about gaps, or the equal gap/material thickness myth.
