NrT UPGRADE KIT DESCRIPTION
Our NrT upgrade kit replaces the Sierra-1 stock tweeter with our highly regarded NrT dome, which features a neodymium ring magnet, a larger tuned damping chamber, a specialized low mass voice coil, and an improved damping system.

Highs are extended with greater detail and energy. Highly recommend for Sierra-1 owners who wish to take their speakers to the next level of performance.
Each kit Includes:
- (1) NrT dome tweeter

- (1) NrT upgrade label
- any necessary gaskets
- detailed instructions
