I hate to be the bearer of bad new's but they are worth very little,maybe $5 to $10 each & that is if somebody really wants them for a restoration,there are a few manufacturers that their raw drivers are highly sought after like JBL,Altec,Stevens,Tannoy,Klipsch,Bozak,Jensen,Utah,Coral,Wolverine ect ect ect.
Phillips has never been highly sought after for speaker systems or raw drivers,i could be wrong on the odd chance that you have mint condition & very rare Feild Coil drivers but standard drivers are just about valueless.
