Also, like Erik said, do not get a speaker with a rear port if you are going to push it up against the wall. Make sure it has a front port.
Actually I was being a little more nuanced than this. Designing a speaker to be on a counter, near a wall requires a different crossover than one designed to be out in the room.
In a close space like that we can forego the baffle steep compensation in the crossover which yields a higher efficiency design. The trouble is, the speaker out in free air will sound thin.
Another option is to use a professional, powered monitor which lets you dial in the amount of bass.
