Most certainly a glass cabinet will affect the performance of a speaker. Two things will happen. First, the glass enclosure will reverberate so the tonal quality of the sound will be changed significantly. Second, the glass will attenuate the sound so the level will be much lower outside the glass cabinet than inside. The high frequencies will be affected more than others so the sound will be muffled. Overall, the sound might be compared to telephone quality instead of a full range signal. If the question is concerned with speaker placement, it is worth moving the speaker away from the preferred position in order to keep it in open air where it belongs. There is no harm in trying the speaker inside the cabinet before a final position is chosen and the effect of the glass will be immediately apparent.
