Incorrect wiring speakers? Pachislo Thunderbirds

[benniebjw]

Hello everyone,

I think there is something wrong with the wiring of my Pachislo Thunderbirds.
I have 2 pictures. One of a Pachislo Thunderbirds that is not mine and one picture of mine Pachislo Thunderbirds.

The LEFT Pachislo on the picture do have extra RED wires to the speakers and a swab/rod glued on the speaker.

The RIGHT Pachislo (Mine) have NO extra RED wires to the speakers and a swab/rod is glued to the plastic inside of the door

Do anyone now where these swab's/Rod's are for? And why i missing the RED wires?
See the differences circled with yellow squares on the photo:
