Paxmate Plus and similar acoustic foams do not mass load but do absorb reflections. Plasticine, Newplast, tungsten putty, Dynamat, etc. mechanically mass load the baffles. Some have used these materials in the cups, too.
Arnaud posted some interesting information and graphs about these topics 20 or 30 pages back, including loose filler to increase the effective size or space of the cups.

OK, I'm formulating a plan. I will take one for the team, be a Maverick, go against the grain, whatever!
My plan is pretty simple but I will have to take a leap of faith. After having read or skimmed this entire thread it seems to me that almost everyone has built on the original mods. I'm going to approach from a different angle. I am not afraid of taking the chance of it not working because I suspect that if all else fails I could probably scrounge a pair of stock cups (Smeggy?) and start over if it's an abject failure.
1st off I want to try damping the cup resonances without reducing the internal volume. This is where the "Quiet-Kote" comes in. This will require completely removing the drivers to spray the cups, so I will also re-cable at the same time (why leave the crappy 6.3mm socket?). Question: Is it really an Aluminum pad on the PCB board of the driver? If so has anyone tried the mineral oil trick to solder copper to the traces?
2nd, I saw LFF's subtle hint at dispersion many posts ago and since his success is the center of much speculation I am inclined to investigate. I have a material in mind that is a natural vegetable celullose that has many random cells of differing sizes, so far it shows great promise (in my simple test) for really evening out the cup resonances without completely filling the cup or covering every surface (don't worry, whether it works or not I will share). In my stock cups I put a slice of this material in without any other material or mods and effect was immediately noticable, smoother coherance across the spectrum. I feel like this one simple step took me about 50% towards where I want to be. But I can still hear the plasticky honk from the cup, though already reduced.
3rd, I think I will try loosely fill the cups with some kind of fiber fill to create the illusion of greater cup volume.
Wish me luck, based on any answers to the above bolded question I might get going this weekend.
BTW- I think I will call 'em ......"DoggyPants!"
PS, I know I'm running mostly on intuition here, but it rarely fails me in catastrophic ways.
