As far as the woofer design I think that is correct. The woofers in the EP subs changed from the Ti days to the V2s, V3s, etc.. I think that is a newer design than what my V2 has in it. Also, the brochures didn't always keep up with new pictures as Axiom changed their technology. This is true for all their speakers.
