If you're looking for front ported speakers because you plan on placing the speaker near a wall, you should be specifically looking for in or on-wall designs with cross-overs designed for that placement.
Speakers designed for free-standing use will have too much low frequency output from the lower midrange on down when placed near a wall.
If you only have a couple feet of room you should be looking for in-wall (on-wall if that's not possible) designs because with that little room reflections off the front-wall will still be fairly loud compared to the direct sound and arriving shortly after it thus interfering with both frequency response and imaging. With in and on-wall designs there aren't really separate reflections.
