Replacing arcade cabinet speakers

These are the speakers currently in the cabinet. As part of my ongoing recondition, I am looking for some bolt in (same diameter or pretty close) replacements with better sound/manufacture quality.




Could anybody steer me in the right direction or give me some specs of what I should be chasing near abouts.

Note: Cabinet has no amplifier now but will be getting a small amp during the cab recondition.

Is anybody with some audio knowledge able to assist please?

Well if it wasnt getting an amplifier I would stick with the 15W speaker but depending on the amp you are getting you can get higher rated speakers.

Try finding some 8ohm 15 watt "free air" speakers that size.

Speaking of speakers, who can tell me what brand/model from the many japanese arcade cabinets came with these?:
