"Can you provide more details about the "mass" you are adding? What are you using, and in what quantities and configurations?"Sure. It's 3M Window Weld. This material is dense/non-resonant and sticks like no tomorrow. I mold it into a ball the size of the acoustic disc and stick it to the top disc. One can make a bigger ball if needed for more mass.
On another subwoofer I had, I just molded it into a ring, much like an o-ring, and placed it around the dust cap where the dust cap and the cone were bonded. Be aware that if the cone/dust cap are made of paper, U will most likely destroy the cone/dust cap if U try to remove the Window Weld! On a polymer cone material, it is no problem.
It comes on a roll and is very malleable. U just remove a small portion and shape it where needed and stick. It is great for dampening driver baskets too due to it's non-resonant nature.
I know of one high end speaker manufacturer that uses this material as the seal/gasket between the drivers and the baffle due to it's excellent sealing and dampening properties.
It can be found at most auto parts stores or ordered on-line.
