I haven't heard it yet, so I could be wrong, but I'd hope that the Atmos channels don't draw that much attention to themselves. I still like a strong front stage. I'm old school I guess.

If Dolby thinks I, or anyone else, is going to hang towers from the ceiling then they are outside of their minds. Of course everyone will use bookshelfish, or 'reflected design' type speakers, with proper receiver bass management. I'm not sure what this has to do with RB 51 IIs however.

The rear ports are part of how the speaker maintains and achieves lower frequencies (sound not done by the tweeter), without further demands on woofer excursion, power demands, and cabinet size. In my experience, the direction of the port matters little. I've seen speakers with front firing ports need ample space from boundaries to tighten bass, and rear firing ports need practically no space. Remember, bass radiates from the speaker like a sphere. The port is simply a mechanism which creates bass. If a port itself demands more space, like more than a few inches, then your bass radiation is less spherical, and to me that's less desirable.
When you're using bass management, let's say crossed at 80hz, the speaker is still using it's woofers to a great deal, and thus still using it's port. Remember that the 80hz isn't a brick wall. The speaker is still playing or trying to play sounds down to probably 30-40 hz, due to the roll off of the cross over. The higher the order the cross over, the steeper the roll off.
