Yamaha 12″ Refoam Kit
This kit will fit Yamaha 12″ speaker models that have an angled attachment to cone. Check for correct dimensions.
Model #’s include:
– NS-A500, NS-A98, NS-A99, NS-A99W and many more.
Each Refoam Kit includes all the materials needed to repair two (2) speakers:
– Refoaming Instructions
– 2 Foam Surrounds
– Shims for Centering the 1.5″ Voice Coils (If Selected)
– Two 3.75″ Screen Dust Caps (If Selected)
– 1 Bottle of Specially Formulated Foam Surround Adhesive
*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.
