If you go outside the pods, they fit in close, inside the pods leaves a 1/4" or so gap.
I am going outside the pods. If the grills are pressed up against the rim of the speakers the tweeter will fit. I took the speaker and put the grill on it and not only does the tweeter hit but the speaker surround also is touching. I think if the pod allows a small gap between the speaker rim and the fairing it will be fine. Judging by all the people here that say the CS grills work I am thinking that is the case. Of course, that would leave a gap that dust and/or water could get into. I guess I am going to have to take it apart and see for myself how this works. Wish there was some good pics online.
