Ohm F 12″ Refoam Kit w/ Spiders
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.
*This kit includes 2 new spiders. The cones are heavy on these drivers and the spiders can sometimes wear down and need to be replaced. The white glue included in this kit will work to glue the outside of the spider to the frame, but not the spider to the voice coil/cone. You will need to purchase a 2-part epoxy from your local hardware store.
Each Refoam Kit includes all the materials needed to repair two (2) drivers:
– Refoaming Instructions
– 2 Foam Surrounds
– Tall Shims (Clear Only) For Centering the 3″ Voice Coils
– Rope Caulk for resealing back in cabinets (72″)
– Two 6.17″ OD Spiders (.5″ tall, 3″ voice coil opening)
– 1 Bottle of Specially Formulated Foam Surround Adhesive
*It can be very difficult to refoam this 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″
