Recently came into possession of an old 1982 Peavey 412s guitar cabinet. Like the size and durability but the Scorpion speakers can't handle the power I'm pushing through it. Don't have much experience with shopping for speakers. Does anyone have any recommendations for speakers to go in a cabinet of this size on a budget? Don't have to sound great, just able to handle some volume. Would like the overall impedance to run at four ohms. Thanks
