49ST4TRK

The ST4TRK is the factory replacement diaphragm assembly for a single ST4TW 1.5-inch bullet tweeter. In high-output systems the diaphragm takes the brunt of the abuse, and when one goes down the rest of the tweeter hardware is usually still perfect. This kit rebuilds that unit with the same 1.5-inch aluminum diaphragm used at the factory, so the repaired tweeter matches the output and voicing of the others in the array. The assembly is field replaceable and requires no glue, which keeps the repair to a bench job measured in minutes rather than a parts order and a curing wait. For installers and competition builders running rows of bullet tweeters, keeping kits on hand means a failed unit never sidelines a vehicle between events. Each kit services one ST4TW tweeter, so buy one per unit. This kit fits the 1.5-inch ST4TW only; the 1-inch ST3TW takes the ST3TRK version.
