I pulled one out, they are marked EP600 woofers. The AMP looks identical to my EP500, probably need to pull that out and look too as now I'm doubting it all. It has dedicated rca in and outs, which the 800 v3 or v4 isn't supposed to have as they use an adapter via the xlr.

So I never got an EP800, I got Frankenstein? Someone at Axiom drunk smile?
