KEF Center Donut Foam 4-Pack Speaker Repair Kit for Models 102, 103, 104, 105, 107, FSK-KEF - Perfect for Home Audio System Maintenance

The Speaker Exchange kit for the KEF Reference 104/2 dust cap replacement consisted of four dust caps, adhesive, a flux brush and instructions. The instructions, although informative, were generic and not specifically for the KEF 104/2 woofer. I didn’t use the flux brush.The dust caps fit perfectly. The provided adhesive had a nozzle sized for a fine, precise application. The setting time was sufficiently long enough to position the dust cap and make fine adjustments. Once dry, it formed a strong, flexible bond. A very small portion of the tube was used to install the four dust caps.Although the documentation wasn’t specific to the KEF 104/2 speakers, there is plenty of information on the web to gain some knowledge before proceeding.I was very happy with the dust caps and the adhesive. Shipping time by The Speaker Exchange was better than promised. They are very good to do business with.
