No. As long as you proceed carefully and the cabinet is not damaged, your warranty remains fully valid. Please use only a manual tool (a 3 mm Allen key or a T15 Torx key, depending on the series) and do not use a power screwdriver.
Before you begin, cover the tweeter with a small piece of painter’s tape. This helps prevent the tool or the loosened screws from being pulled in by the tweeter’s magnet. Once the screws are loosened, gently tilt the cabinet forward so the tweeter can slide out toward you.
