Do open baffle designs matter?

Was trying to build of pair of open baffle "cabinets", and was wondering if the design for open baffle matters? Or since it's an open baffle, with no back, does it not matter? Logic would tell me as long as the speaker is held up with nothing closing it in, it would not matter. However, that is a complete guess. Obviously different material would cause for different sound possibly. I am more curious with the design of the open baffle.
