[QUOTE="maylar, post: 8162111, member: 541144"] It's not about cancellation, it's about air flow. Easy to prove - close the trunk slowly while someone listens inside. If it's reflected waves coming back to cancel, then you should hear the drop in volume as the trunk lid comes down. You won't. Not until the trunk is nearly fully closed and sealed. Or cover the trunk lid in some sound absorbing material like CCF. That should diffuse the reflected waves and at least change the difference open/closed. It won't. [/QUOTE]
