Really old thread, but makes sense to comment here instead of creating a new post.

What exactly is meant by this?
Does it meant the box is too large for the speaker or too small?
I'm enquiring about this particular instance because I recently built 2 boxes for 2 unknown 12" speakers (no markings at all), and they are pulling inward in the box, but play fine when outside of it.
The boxes look oversize for the speakers, but never knew any such effect was possible, so any professional information will be greatly appreciated. thanks
