Oh you'd be surprised. Probably a sticker with 'Made In China' printed on it. Maybe an impedance & notional power handling capacity number.. I've seen the backs of a good few budget end speakers & you're not as likely to see part numbers as you are with the likes of RCF etc.
If there isn't a Wharfedale dealer around anymore who stocks spare parts try BlueAran & see what they know.
