Congrats! I've got some of those myself, but of the other model (the ones without the external wiring stud).
It's amazing how that mono-tweeter pops you right awake from a sound sleep. Three or four years later, it's amazing how you can ignore it during dinner when it's only a couple of feet away.

Watch out for new speakers. As my better half pointed out, "will the new speakers really make the Disney princess soundtracks less annoying?"
