Realistic Mach One 15" Refoam Kit
This is the correct kit that fits on the Mach One 15" woofers. It will also fit the Mach Two and Mach Three woofers, the surround roll is a little larger than the original, but will still fit fine. The foam has an angled attachment to cone.
Check for correct dimensions..

Each Refoam Kit includes all the materials needed to repair two (2) woofers:
- Refoaming Instructions
- 2 Angled Foam Surrounds
- Shims For Centering the Voice Coils
- Two 5.3" Paper Dust Caps
- 1 Bottle of Specially Formulated 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.
