Dahlquist 10″ Refoam Kit
This kit will fit the Dahlquist DQ-10, DQ-20, DQ-20i and M907 10″ woofers. They have a flat attachment to cone and a masonite ring around the outside of the basket which the foam surround is mounted inverted (concave).
Each Refoam Kit includes all the materials needed to repair two (2) woofers:
– Refoaming Instructions
– 2 Foam Surrounds
– Shims For Centering the 1.5″ Voice Coils
– Two 2.75″ Felt Dust Caps
– 1 Bottle of Specially Formulated Foam Surround Adhesive
*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.
A – Outside diameter of the surround = 9.875″
B – Roll ends = 8.875″
