Infinity RS 4001 Refoaming Question

Hi Folks,
I am in the process of refoaming the woofers on a pair of Infinity RS 4001 Speakers and I hit upon a snag. The woofers have this hard plastic gasket/covering that seem to be stuck firm on the drivers. This plastic covering goes on top of the foam surrounds and I need to remove them for the refoaming. I was wondering if anyone knew how to remove them. Are they stuck on or do they clip on to the metal frame of the driver and there is a trick to remove them?Any suggestions would be appreciated. Here is a picture of the driver and the plastic rim/covering/gasket on top of the surrounds.

Yup. Got the rings off. Was impatient and broke one. :( super glued them together. The surrounds go on tomorrow.

Alright folks. The refoaming went swimmingly well, except for the excess glue streaks on the cone. I probably used too much glue so there was some seepage of the glue from under the foam onto the cone. I let the glue cure on the cones for a day and then glued the outer edges to the frame. Let it cure for another day. Mounted the woofers on to the cabinets and let it rip .. Sounds good !. The speakers sound almost exactly like I expected them to, except for one thing, cabinet resonance at low-freq. I played some tracks from the Chesky Audiophile demo disk. These tracks have plenty of bass guitar work around 50-60hz and while they sound nice, I can sense some cabinet coloration.. I went over and put my hand on the cabs and wow.. the whole cabinet was resonating like a gong.. hmm.. I guess the cabs are not inert as i thought. Compared to my main speakers (polk sda-2s), the cabs definitely need some bracing / damping.. I am going to get some automative rubber underbody spray and spray multiple coats of the compound on the inside walls of the cabs..Lets see if that makes a difference..

Well, I wouldn't do that yet. A brace on the inside is a better start. With the woofer out, cut a peice of wood (Probably 1"x2") to fit snug from front baffle to the rear of the speaker, positioned right above the woofer below the mid. Use the screw hole that is already there on the bottom of the midrage to hold the front. You wil have to drill a hole and use a fresh screw to hold the back. (but who will see that anyhow?) You will also want to use a little bit of glue in addition to the screws. I've also heard of people putting glue on the edge seams but have not tried that myself.

The automotive spray will add some mass to the front baffle and may help some but not nearly as much as a brace.

I do have some 1"x2" around so I will try that.. Hate the idea of drilling some holes though. Will try some wood glue..
