HD7 and more

Each Refoam Kit includes all the materials needed to repair two (2) woofers:

– Refoaming Instructions

– 2 Foam Surrounds

– Shims For Centering the 1″ Voice Coils

– Two 2.25″ Screen (thin fabric) Dust Caps

– 1 Bottle of Specially Formulated Foam Surround Adhesive (strong and sticky to bond on the poly cones)

*It can be difficult to refoam a speaker 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 refoamed. If you do not use the plastic shims, the voice coil may be off center and it may lead to the voice coil rubbing. If you want to leave the original caps on, you can try to center it by hand.
