@dlm110 They are rear ported. However, this may not be a deal breaker. I used to think that front porting made a big difference to placement, but that is not true.
"For all intents and purposes there is no appreciable difference between a rear- and front-ported speaker. They both do the same thing – use the energy created by the woofer when it moves backward (or ’in’) to enhance bass response. The practical issue with a rear-ported speaker is how the energy coming from the cabinet interacts with the boundary behind it. Energy waves bounce off the nearest boundary (for our purposes we’ll call it a “wall”) and interact with the direct energy from the front of the speaker. This interaction may result in either a dip or boost in energy at certain frequencies that will make the overall sound in that frequency region muddy or inarticulate.
There is a school of thought that says rear-ported speakers should never be placed near a wall, and if you are going to place your speakers near a wall you must always use front-ported or closed-box designs. This is simply false. Are there a few things you can do to optimize the performance of a rear-ported speaker near a wall? Of course, but superlatives are always suspect, especially when it comes to audio."
