Cutting a hole in the back of shelf for speaker?
So I've got my klipsch RB-51 II bookshelf speakers on the second shelf in my entertainment center. Just found out yesterday we are expecting, so within a year and a half we will have little hands again. Speaker stands can't be an option now. The problem is my entertainment center panel that covers the back of the shelves rattles when the speakers are turned up due to the air coming from the port. Its real wood, but very thin. I had considered cutting a 4x6 or 6x8 hole in the back around the rear port to allow it to breathe out the back of the shelf instead of pounding air against it(and I mean it pounds!!). So, has anyone done this, or will it work?
To cover it up, but still be able to breathe I was going to get some charcoal fiberglass screen like what goes on screen doors and windows. Should be dark enough to match the dark dark cherry entertainment center, but still allow air to flow. Speaker grill mesh doesn't breathe good. There is some room behind the entertainment center. About 6 inches.
