Acoustic with wood panel


Hello,

i’m curious to know wich effects on sound will have this kind of slate panel on sound if they are behind speakers.

These panels do not have an absorbent felt between the wooden slats. This is full mdf.

Your opinion?

Well I'm not sure where exactly you want to put MDF and what you have right now.  If you have drywall and putting an MDF panel in front of it it will be roughly equivalent.  Depending on the location and your room's existing layout and treatments that may not be what you want there.

Your description isn't very clear. However, if this product is bonded to the drywall, it should reduce vibrations and structural resonance. I suspect, you may find a little added liveliness to the sound compared to drywall. 

It won't be any different than a bare wall behind the speaker. Any effect would be at very high frequencies and would not be discernable.
