Yes vid, it makes a difference. The front and rear of any bass producing speaker should be sealed from one another or they will cause cancellation.
The frequency at which this cancellation will occur is inversely proportional to the size of the baffle. Hence, if he seals the space immediately around the speaker, the baffle size will become very large and hence cancellation will occur at a very low frequency that falls out of the speaker's range.
