For the rest of you that purchased a PA-120, how was yours packaged? I received mine today, and the box contained a foam insert protecting the top of the subwoofer, but there was no foam insert to protect the bottom of the sub. Judging from the size of the box and its contents, it looks like the box was sized for an insert on both sides. Unfortunately, mine arrived damaged. I'd like to get some idea of whether the inadequate packaging was an isolated incident, or whether this is the normal packaging (and it's been good enough to keep it protected in most shipments).
