Helmholzresonator: holes instead of slots !?

Hi first of all sorry for my very bad english. How everybody here i have a question is it possible to build a slotresonator with holes instead of slots ? i think it must work the same but its more easy to get the right distance for the slats, when you need little slats about 1mm. i will be happy for answers peace mika
