Polk LSiM 703 Upgrade Kit (Pair)

This upgrade kit supplies all of the necessary crossover components needed to rebuild the stock crossover with greatly improving parts quality.
The new crossover will need to be built & kept external to the cabinet.
The kit also includes wire, solder, heat shrink, tube connectors and a sheet of NoRez.

We also offer the option of budget poly caps or Sonicaps for the tweeter circuit.
Depending on how you wish to wire the speaker, we also have the option for extra sets of tube connectors to replace the stock binding posts.
