Teledyne Acoustic Research AR90 Refoam Kit
This is the correct kit that fits on the 10″ woofers and the 8″ mid bass speakers. 6 speakers total.
Each Refoam Kit includes all the materials needed to repair four (4) woofers and two (2) mids:
– Refoaming Instructions
– Two 8″ and Four 10″ Foam Surrounds
– Shims For Centering the 1.5″ Voice Coils
– Six 3.25″ Screen (thin fabric) Dust Caps
– 1 Big Bottle of Specially Formulated Foam Surround Adhesive.
*It can be very 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.
