I have the M2OW. They have two vortex ports on the bottom. The M5OW likely have those also because they are spec'd as reflex/vortex.

I love the M2OW! See my two reviews at the link below.

The M5 bookshelves are leaps and bounds better than my old M80v2 - in every way. And they image and soundstage better than M100s in my rooms. I hope your M5OW are as good.
