5. Installation Instructions

5.1 Removing the Old Surround

Step 2: Using a razor knife, carefully slice down the middle of the damaged surround all the way around the speaker.

Step 3: Slowly and carefully peel the damaged surround from the cone. Exercise caution to avoid damaging the cone.

Step 4: Slip the point of your razor knife between the gasket and the speaker frame. Apply pressure and slowly turn the speaker to cut the gasket away from the frame. You must be very careful to salvage the gasket to reuse it later. NEVER pull the blade toward you. Carefully remove the gasket and set it aside to reuse later.

Step 5: Using a chisel or your razor knife, remove any and all foam residue from the speaker frame. You do not need to remove all of the glue residue, but you MUST remove ALL of the foam residue.

Step 6: Using a cotton swab, apply rubbing alcohol to foam and glue residue around the edge of the cone. Do not be afraid to saturate the cone edge if it is made of poly; be more careful with a paper cone. Allow to soak for 1-2 minutes.

Step 7: Using your thumbnail, or a razor blade held perpendicular to the surface, scrape away all foam residue. Be VERY careful not to damage the cone. Especially if you saturated it in the previous step. While scraping, use your other hand to gently provide additional support from underneath the edge of the cone.

Step 8: Use a paper towel or a soft cotton rag dipped in rubbing alcohol to gently do a finishing wipe-down of the cone edge and speaker frame. Allow cone and frame to dry completely.

5.2 Attaching the New Surround

Step 9: Place the new foam surround in place upside down to test fit. Use your fingers to move the cone into place and make a visual note of how the new surround will lie in relation to the cone. Read ahead before continuing because once you hit the next step there is no turning back.

Step 10: Read the instructions included with your adhesive, and move to a well-ventilated area prior to continuing. With the surround still in place upside down, carefully apply a small bead of adhesive to the innermost flange/lip of the surround. Use the bottle tip to evenly spread adhesive around the inner flange/lip as it is applied. Allow the adhesive to breathe for a few seconds.

Step 11: After allowing your adhesive to breathe, carefully pick up your surround, flip it right side up, and carefully lay it in place. Be sure to lay it in place correctly the first time, as it will begin to stick immediately.

Figure 10: Placing the surround.

Step 12: With the new surround properly placed, use your finger, the butt end of a sharpie, or something similar to gently press the surround into place. Slowly trace your way around the edge to help the adhesive bond to the cone. Carefully repeat this step 3-4 times over the next 10 minutes.

Step 13: Use a paper towel lightly dampened with warm water or nail polish remover to clean up extra glue residue before it dries, and then Take a 45-60 minute break...

Step 14: Now that your first adhesive application has cured a little bit, use the butt end of your sharpie to gently hold the outer edge of the surround away from the frame while you apply adhesive to the surface of the speaker frame where the surround will attach. Apply adhesive all the way around the frame. Allow the surround to fall into place on the frame.

5.3 Final Adjustments and Curing

Step 15: Use your fingers to apply pressure evenly to the center of the cone. Listen for any rubbing or scratching sounds from the voice coil as the cone flexes in and out. Adjust the cone side to side until the cone can be manipulated all the way in and out without any rubbing.

Step 16: As you did in Step 12, use your sharpie to press the surround gently into place on the frame. Repeat Step 15.

Step 17: Repeat Steps 15 & 16. Apply adhesive to the underside of your original gasket, or a replacement if you purchased one. Align the holes in the gasket with the mounting holes in the frame, and set the gasket in place. Press the gasket in place.

Step 18: Repeat Steps 15 & 16. Pick up the speaker and place it face down on a hard, level surface. This will allow the weight of the speaker to press the gasket permanently into place while the adhesive cures.
