Old TV speakers, but what is the deal with the fiberboard used on the port slot? (lemmy.world)

You can see the outside on the edge of the top speaker (bottom-right corner). The wood is thin, maybe 2mm, and glue applied likely by a machine, yet the slot length looks like it was intended for tuning frequency response. But why wood, and only for this one side of the one slot in an otherwise plastic housing?
