The Rockford Fosgate ND4-R 4-inch Tweeter is a high-performance speaker component designed to deliver exceptional sound quality in automotive applications. This tweeter is part of Rockford Fosgate's Prime series, which is renowned for its ability to provide accurate and detailed sound.

The ND4-R tweeter features a 1-inch PEI dome tweeter with a neodymium magnet. PEI (Polyethylene Ion) material is known for its rigidity and stability, ensuring the tweeter maintains its shape even when being driven hard. Neodymium magnets, on the other hand, are powerful and lightweight, making them ideal for use in compact enclosures.

The tweeter's frequency response ranges from 2.2 kHz to 23 kHz, allowing it to reproduce the full range of high frequencies that contribute to the clarity and detail of the sound. It also has a nominal impedance of 4 ohms, making it a versatile choice for various automotive audio systems.

The ND4-R tweeter is engineered with a vented voice coil former, which helps to reduce thermal compression effects, allowing the tweeter to maintain its sonic performance even during long listening sessions. It also comes with a rubber surround that provides flexibility and durability, ensuring consistent performance in various temperature and humidity conditions.

Furthermore, the ND4-R tweeter is designed with a mounting depth of 1.8 inches, making it suitable for standard size speaker cutouts in automotive applications. It also comes with a grille that not only protects the tweeter from external damage but also adds an aesthetic appeal to the car's audio system.

In summary, the Rockford Fosgate ND4-R 4-inch Tweeter is a high-quality and versatile speaker component that delivers clear and detailed sound in automotive applications. Its use of PEI dome, neodymium magnet, vented voice coil former, and rubber surround ensures consistent performance and durability, while its standard mounting depth and included grille make it a practical and visually appealing choice for your car audio system.

Rockford Fosgate is a well-known brand in the automotive audio industry, and the ND4-R tweeter is one of their offerings.
