Take the grill off the sub and if you see 2 drivers than you have the EP800. If there is just 1 driver it is the EP600. You can also check the sticker at the back of the sub which will tell you exactly what model it is.

In the past I have seen EP800's delivered in what is labelled EP600 boxes with a 800 sticker covering the 600 portion.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
