Any info is extremely useful!
Yes, using a hole saw may be the best thing in my opinion. Making your holes as large as possible while maintaining the integrity of the frame is something to keep in mind. Allowing the sides of your panels to absorb sound (breath) as well, will help maintain a good overall acoustical "balance" with your traps.
You might want to consider using a 1/4 inch round over bit on your router for better aesthetics though if making such holes. Just a thought..
I hope that helps. thumbsup
