Acoustic Research 12″ Refoam Kit
This kit will fit many AR 12″ speaker models that have an angled attachment to cone. Sometimes these woofers are considered 11″.
Check below for dimensions.
Model #’s include:
– AR3a, AR9, AR11, AR91, AR58b, AR58s and many more.
Each Refoam Kit includes all the materials needed to repair two (2) woofers:
-2 Foam Surrounds
-Shims For Centering the 2″ Voice Coils
-2 Screen (thin fabric) Dust Cap (2.75″ is most common)
-1 Bottle of Specially Formulated Foam Surround Adhesive (Choose white glue for paper cones or black poly glue for poly cone woofers.)
*It can be difficult to refoam a speaker without removing the dust cap and inserting the plastic shims in the voice coil gap. 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.
