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
