I bought a older sony ES but can't find any info?

the other day I was killing time walking around a pawn shop and had seen a sony ES 10" XS-1055LG single 4ohm VC but I can't find crap on the thing but it sounds real nice on a P200.2 bridged in a sealed box at 1.6cu.ft. It only ran me 30.00. It says 300rms but 1000max I have no specs and no idea how much power to throw to it? It looks like it can take a lot it has a aluminum cone/VC made as one piece and a flat wound coil double stacked magnets and a fixed heatsink in the center of the cone face attached to a spider that is attached to the cone kind of like a old Cerwin Vega stroker?
