Iirc, the hole does 2 things. The first isn’t acts like a sound hole in a guitar or violin and alters the tonal qualities of the speaker (the enclosure acts like a resonate chamber.)
Also, iirc, drivers have to work harder to move the membrane of the enclosure is totally sealed, since it’d have to compress the air inside/behind the membrane.
Of course, cheap speakers probably did it because they say JBL and others do it on the expensive studio monitors.
