both of my m80 boxes had huge gashes down the sides and I could see the speakers through the cardboard.
The m80's were fine though.
Ditto that, just a month ago. It was scary. The problem is that with the single box, there is a lot of "air space" between the cardboard and the speaker, because the styrofoam protective pieces are only inserted at the top and bottom of the speaker. So, when someone grabs it or pokes it from the side, the box is really easy to pierce.
Double boxing would help a lot, or putting foam inserts in that go the entire length of the box top to bottom.
