If the baffles are acrylic and tightly fit then it's possible the acrylic swelled as it slowly took on some water causing increased outward pressure leading to an eventual cracking of the glass. Extruded acrylic will take on slightly more water and swell more than cast. Hence the reason baffles should either be made of like materials or not fit too snugly.
damn i think you may be right! i think the acrylic was prett tight. i'm going without baffles this time anyways to lazy to do em again.
