This upgrade kit includes everything you need to take this speaker to the next level: All Crossover parts, wire, heat shrink, solder as well as a set of Tube Connectors and 2 sheets of NoRez.

RP-5000 V2: This kit is NOT compatible with the newer RP-5000F II it has changes to the drivers and waveguide that this kit does not account for.

RP-250F: This kit IS compatible with the older RP-250F, the only known difference is a small change to the back of the tweeter. The woofers, waveguide and stock crossover are the same as the 5000F.
