Darius 2x15 cab, need info

Hey guys, so a buddy of mine who know I’m looking to build a new rig found a cab for sale near me (Vancouver bc) and told me it was a vintage 215. He asked me if I wanted it and I said sure how much? Well turns out I’m the proud new owner of a Darius 2x15 cab for the hefty price of a case of beer ($30). My issue is I can’t find any and I mean any information on it at all? I’ve found company info , that they are/we’re a Canadian company under the Ahead Corp in the 70s but outside that I’ve got nothing. Does anyone know anything about it? It sounds amazing, but I’m unsure of literally everything related to my rig and use of it (ie wattage, speakers, ohms etc)
Your help is much appreciated
