of course you can block it, but you will get a very bass heavy sound. Since they are for rear use you can probably get away with it though. If possible leave a 4-5" between the wall and speaker and that will help.

Also, ported cabinets tend to be larger than what is optimal for the same speaker driver in a sealed enclosure, so you may want to experiment with adding some more poly to the inside of the cabinet when you have the port plugged.

I may be wrong here, but one of the reasons ported enclosures became popular was to achieve low-bass response without the huge cabinets required to do so in a sealed "acoustic-suspension" design.
