So you want small washer size rings cut out of the Neoprene 60 and then the caulk fills in the air gap created? As opposed to buying sheets of the neo to make 6-1/2" diameter rings? Just checking.

Awe-d-o-file,
If it's possible to buy black 1/16” Neoprene 60 Duro gasket rubber rings customized to fit to the exact dimensions of where your tweeter, mid-range and woofer are screwed into each speaker cabinet, then by all means purchase them and save yourself the hassle. Otherwise I recommend marking up and cutting a paper version of each size in order to cut each rubber ring. When buying 1/16" thick Neoprene at the hardware store, why not pick up brass replacements for the ferrous speaker screws and say 'goodbye' to 36 distorting sources of EMI at the same time?
After inserting each rubber ring and screwing the speaker box back into the cabinet, you'll observe that the speaker box is now raised up a 1/16" above the surface of the speaker cabinet. That unevenness disrupts the smooth flow of the exiting air-pressure so causing the music to sound rough. Filling in the triangular gap between the speaker box and cabinet with rope caulk or an equivalent is therefore critical to the success of this remarkably effective tweak.
I hope this clarifies everything to your satisfaction.

It would be for 8 tweeters shaped like a Peerless (rectangle w/rounded corners) and 16 6-1/2" drivers. 96 screws too and I can't remember if they are wood screws into wood or machine screws into a metal sleeve which would still leave other metal there. I guess the key is non-ferrous metal right?Anyway I'm still not sure if you mean to simply put a rubber washer like cut out w/each screw or a cut out that goes all the way round the outer perimeter of each driver. If the latter sheets 7X7 inches are larger would do best. I've seen rolls or reels of 1" wide stuff too but that's nearly impossible to work into a circle for the 6-1/2" drivers but could be made to work for the rectangular tweeters but not very easily.
Sorry for the thick skull here

Awe-d-o-file,
The speaker boxes are inserted through holes in the front of the speaker cabinets that are large enough to take all but the outer rims. Holes in the outer rims are what you tighten wood screws through to hold the speaker boxes to the cabinets. The flat rubber rings go around the perimeter of those inset cabinet holes designed to tightly fit the speaker boxes. So you will have wood cabinet, rubber insulating ring and then the metal or plastic speaker box in that order.
You cut the rings out of the flat sheet (7" x 7" would likely do fine for most speaker boxes) of black 1/16” Neoprene 60 Duro gasket rubber to provide a flat perimeter mat for each speaker box. Forget about narrow rolls.
Good luck!
