Hi
I got to thinking about the acoustic effects of a mesh in front of the drivers.
If the mesh is 1mm metal and the holes are 4-5mm the effects are probably minimal ( as this is standard for many PA-solutions).
But what if the mesh was much thicker? - say 20mm? and the holes were Ø30mm? I'm guessing the holes will have an resonance somewhere in the audible spectrum. Below resonance the holes will make little difference, - as long as airflow is kept below turbulence. What happens above resonance?
I'm wondering if the holes could be tuned to give a boost over a (small) range?
Most of all I'm curious 🙂. Hornresp can do a lot, but I cannot figure out how to put this one into HR.
Kind regards TroelsM
