Those speakers are aftermarket. OEM roll hoops have open space. It'd look better without them in there. I know later years Honda integrated speakers housed within the roll hoops, but those are useless from what I've heard from owners.
Honestly, the S2000's premium sound system is the pipe(s) that exit in back. Honda's poor excuse for a radio in the car is useless over 60 mph. Those speakers installed in your roll hoops might help a bit, but I'm not sure I'd want a speaker that close, blasting the back of my head.
