Eric,

in my experience, the tuning frequency of a port (and it's interraction with your primary room resonances) is far more important than the orientation.

Sadly I don't know what the ports on both of those speakers are tuned to (you could probably ask the manufacturer), but if you can find out, try to compare this with the results from the Cara room simulator and see if the port tuning corresponds with one of your room resonances.

I would say, from past experience, that the Crafft (which employs the D330 tweeter) is the better allround speaker, provided you have the amplification to drive them.
