I have just resealed box with caulk because port walls were moving everywhere. Sounds amazing and bangs hard, although, I just noticed the left wall of the box vibrates. It is visually noticable, as well as heard. If I push wall in, to stop vibration, it makes a cleaner and deeper sound. I'm not sure what to use to fix this without going back inside the enclosure. Would liquid nails work? Looking for suggestions, thanks!
