Why not just mat and resin the ring scaffolding into place? A little extra framework is well worth it.Just make sure you actually mat and resin the whole structure, especially the fleece. Fleece and resin is not strong enough to withstand the forces of a subwoofer. The fleece is just for shape it still has to be glassed just like the base for the same strength levels. Once the fleece is completely soaked and sturdy you can go ahead and remove the sticks completely, they were only there to get the ring positioned, you don't need them in there any more.
