As far as I can tell, there is no marking on either the speaker itself or the packaging to say what the Ohm rating of the speaker is. While this isn't too much of a problem for me as I only have 1 Eminence speaker so it shouldn't be that hard to remember, if I had lots of different speakers of multiple types and ohms, I'd have to keep lists of them all.
Obviously it's easy enough to write something on the back of the speaker, but really I shouldn't have to as this kind of thing really ought to be clearly marked by the manufacturer, especially as using the wrong impedance could damage an expensive amp.
