JBL MR38 Narrow Surround Refoam Kit
This kit will fit the JBL MR38 speakers and more. These woofers have unique narrow roll surrounds that generic surrounds will not fit.
The mids are part # P206H and woofers are P208H.
Each Refoam Kit includes all the materials needed to repair four (4) speakers:
– Refoaming Instructions
– Two 6.5″ Foam Surrounds for the Mids (F6-8)
– Two 8″ Foam Surrounds for the woofers (F8-12)
– Shims for the 1″ Voice Coils (If selected)
– 1 Bottle of Specially Formulated Foam Surround Adhesive (Dries Clear)
*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. You can reuse the original dust caps by carefully peeling them off the cone and regluing them back down when the repair is complete.
