You still have a seal between the front and back of the speaker but the back edge is just opened up. This is not an issue with metal rings like VP provides or the one I used to make because they were so thin it did not impede airflow. That's part of the challenge of using a material that does not have much strength when thickness is limited.
i see, so if i sanded/chamfered the adaptors all around the inner edge, it should help air flow behind the cone. this will have to be a very delicate operation involving my leather door panel and a sanding machine i think
