From what I understand the V's outperform the Orion's, expecially the Super-V, and are much less headache to get into because you only need one small amp to run it. The Orion requires several high power, high dollar amps to sound its best.
So cosmetic similarities of the OB section aside, I know which one I'd pick

.
Just look at all the thousands and thousands of square shaped, sealed monitor speakers! And yet they all manage to be different from each other.
Sometimes basic simlarities of design are unavoidable, one would figure this to be pretty obvious stuff, like how most of the highest performance sportbikes are inline 4 engines, nobody gets on a Honda forum and says they're copying Yamaha, Suzuki, Kawasaki, etc, it's just a given. OB design and speaker design is some esoteric stuff to me, and given Danny's sterling reputation, I would assume that there aren't many options for achieving compact, dual ob subs in a floorstanding speaker. I do notice that no one else has theirs slanted as in the V2.
Really a moot point. Completely different designs entirely when you look at them. Even in my noob estimation the only similarity is a cosmetic one. I'd also place my bet on the V series being the one to go for.
