Bass trap positions

Does a given bass trap do the same job in different positions? Here is a measurement showing an empty room (grey), and a single trap on the left side front (red) and rear (green).

You can see that below 100 Hz the front corner closer to the speakers is a little more effective, but around 120 - 160 the rear corner is a little smoother.

In this example, the trap is a very small foam one which is not very effective. You can see slight differences with the right front corner (dark grey) and left rear corner (blue).
