Anyone recognize these speakers in my Beta Lead 4x10 combo?

I realized one of my speakers is torn in 4x10 BL combo and want to get a pair to swap in. Not looking to find original speakers, just something modern that will work with 2 of the originals. The problem is they are unmarked and I have no idea what wattage or impedance is in there now. I know it's wired for 4ohms but not sure exactly how it was wired. Any idea what came in the OG Beta Lead combos? Thanks for any help.
