– Repair Instructions
– Two 7″ Rubber Surrounds (R7-1)
– Shims for centering the 1″ voice coils
– 1 Bottle of Specially Formulated Surround Adhesive (strong and sticky)
*It can be difficult to replace a surround on a woofer without removing the dust cap and inserting the plastic shims. The plastic shims are used to center the voice coil and cone assembly while the speaker is being repaired. If you do not use the plastic shims, the voice coil may be off center and it may lead to the voice coil rubbing. These models you can peel the dust caps off the cones and reuse them when the repair is finished.
