Our water treatment is an industrial chemical that we purchase commercially by the gallon. It is a toluene, base which is a strong solvent, and it is applied to the paper cone of the speaker. It saturates the entire cone and pushes the chemical through to the other side. We let the speaker out-gas for 24 hours and then repackage it. You can place the speaker under running water, and not a drop will stick, it is quite amazing! Also, it adds a negligible amount of weight to the cone body therefore not changing the sound of the speaker at all.
The PA1010 woofer is specifically designed for use in the bags of a Harley Davidson motorcycle. They are capable of producing strong bass tones from 37Hz up to 65Hz. They are intended to be mounted semi-sealed in the bag but will also perform nicely in a tuned and ported bag.
