Ohm F 12″ Refoam Kit
This is the correct kit that fits on the Ohm F drivers. The inside lip of the foam surrounds are angled down slightly to make it easier to attach to these unique cones. Check out the pictures above of a driver that was refoamed.
Each Refoam Kit includes all the materials needed to repair two (2) drivers:
– Refoaming Instructions
– 2 Foam Surrounds
– Shims For Centering the 3″ Voice Coils
– Rope Caulk
– 1 Bottle of Specially Formulated Foam Surround Adhesive
**It can be difficult to refoam a speaker without shimming the voice coil. 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.
A – Outside diameter of the surround = 11.625″
B – Roll ends = 10.75″
C – Roll starts / O.D. of the cone = 9.625″
D – Inside diameter of the surround = 9″
