Securely seal the area around the dustcap with painter's tape. This prevents dust from entering the interior of the woofer. Then remove the foam remains from the woofer frame. First scrape away the coarse residue, then clean the frame as clean as possible with a cotton swab dipped in alcohol or another solvent. If necessary, roughen the clean frame slightly with a scouring pad.

The frame of the woofer is now completely clean. Support the cone with your hand and carefully remove the adhesive residue from the cone edge. Do not remove too much as this may damage the black coating of the woofer.
