The Kube 107.2 is not the best option for a 1st gen 107 speaker. It may work, but the crossover is different.
However, the claims (I've read them too) that the Kube is serial matched for each pair of speakers is a bit of hogwash, I could not tell a difference in the 3 Kube's I ran with my 107s.
The 107 is still a fantastic speaker. I would have kept mine if I didn't need to fund another speaker purchase. Don't be put off by the extra piece of electronics to run them, many speakers are tied to extra bits as part of their design including the new $30k Jubilee. I wish I has the room and the funds for that one. :-)
