Infinity RS4000 & RS4000A Woofer & Midrange Speaker Refoam Kit
Each Refoam Kit includes all the materials needed to repair two (2) woofers and two (2) mids:
– Refoaming Instructions
– Two 8″ Foam Surrounds
– Two 3.5″ Foam Surrounds
– Two 2.25″ Felt Dust Caps for the Woofers (If Selected)
– Shims for Centering the 1.5″ Woofer Voice Coils (If Selected)
– 1 Tube of Specially Formulated Foam Surround Adhesive (strong and sticky to bond on the poly cones)
*These speakers are easy to refoam and to center by hand (Recommended). *If you prefer to shim the voice coil and use new dust caps on the woofers, they are available for an additional cost. This can be difficult on the woofers, because under the foam dust cap there is another black plastic cap that is glued onto the top of the voice coil. The voice coil can be damaged if your not extremely careful removing it.
