It depends on the speaker. Obviously with a rear ported (or passive radiator) design, you're not going to want it right up against the wall, but even acoustic suspension models generally fare better with a little space between them and the back wall. I know of no rule of thumb that gives precise values. Best to check the manual for the speakers in question, if you can find it. And if not, experiment.

I concur with swechsler and add the following. Ther distance from a wall with a rear vented enclosure should be at least equal to the diameter of the vent. I feel it safe to assume this would be the same with two vents. Ergo, 3" for either a single vent of 3" diameter or two such vents.
Using that same logic, it would seem that for a rear passive radiator, the distance should be equal to the effective piston diameter of the passive radiator. This would be 6 3/8, 8 3/8, 10 1/2 and 12 5/8, 15 (inches) for 8", 10", 12", 15" and 18" radiators, respectively.
For a sealed cabinet, "theoretically" max bass output would be with the enclosure against the wall. This does not mean it will sound better, Many sealed enclosures have been placed a couple of feet from any wall.
It's very subjective but regarding the vents or passive radiators, no obstruction should be present as per the above.

That's actually a good point. Presumably, at some point when it's close enough to the wall, the space behind the speaker will act as an extension of the port and adversely affect the tuning.
