Cons: cannot add more weight for lower frequency tuning, foam rubber surround that will rot with time, one of the radiators had an air leak which had to be glued i.e poor manufacturing
Pros: easy to modify (gluing more weight) I was able to get the frequencies I was after, performs well and has reasonably large excursion.

for what it's worth
I bought these passive radiators and installed them. I noticed that one of them moves visibly more than the other one does. I can't be certain that it is due to inconsistency on the part of Boston Acoustics because I haven't swapped the left for the right one and watched them go. The system sounds good though. I wish I had the time to try one of the subs sealed and one with the passive radiator, but I never tried that "A B test". they do look cool.
