SRM150 bag

[RoadRanger]

I bought a SRM150 with the bag and can't figure out how the bag is supposed to work. With the foam/storage compartments in the bottom as it came it is top heavy and doesn't hang from the shoulder strap properly. I've not yet tried to pull out the foam - I don't think it will work on top of the speaker in the bag? Anybody had any experience with this?

Here's an Amazon review describing the issue:
