ov.2 is top of the line for eD right now, till the a series comes out but i don' know if they will release it, the ov.2 will have better output than kv.2, both are excellent subs from what the eD guys and the reps are telling me, if your on a budget go kv.2 if money isn't an issue go with ov.2, oh yeah, depends how much juice your goin to feed them
