Price is per pair.

This upgrade kit includes all of the necessary crossover parts needed to take this speaker to the next level.
Kit also includes: wire, solder, heat shrink, a set of tube connectors, a replacement back plate, and 1 sheet of new NoRez.

Note: You will need some new gasket material to help seal the new posts against the back of the speaker. Blu-Tack or thin gasket strips will all work well.
