Search array of objects

I have an array of 50+ arrays each containing 300+ objects as elements.
Each individual object looks like

  type: "text",
  id: "text01",
  content: "Turn to left",
  disabled: false,
  bg: "small.jpg"

So the entire array looks like

  [obj1, obj2, obj3...],
  [obj1, obj2, obj3...],
  [obj1, obj2, obj3...],

That is, every sub-array has the same number of objects: 'content',
'disabled' and 'bg' may differ from sub-array to sub-array.

I need to change the value of 'bg' for the "same" five objects across
all the sub-arrays.

Currently I'm looping through the top level array and then each object
in a sub-array looking for the objects in question. Is there a more
efficient way to do this without looping?
