Buying Options

The CF18N-4 3/4" carbon fiber dome tweeter from Dayton Audio stands out as an excellent choice for those looking for excellent sound quality in compact audio systems. Designed with advanced materials, this tweeter features a woven carbon fiber diaphragm that ensures excellent transient response and clarity, allowing for accurate high-frequency reproduction. Additionally, the CF18N-4 delivers excellent off-axis response thanks to the small diaphragm and sculpted aluminum faceplate. This makes it particularly well-suited for three-way loudspeakers, car audio installations, or anywhere space is at a premium but high-fidelity is a priority.

This tweeter is equipped with a powerful neodymium motor, which reduces size without sacrificing performance. A reinforced damped rear chamber enhances the CF18N-4's acoustic performance by minimizing unwanted resonances to deliver smooth response and low distortion. Finally, the Ferrofluid-cooled voice coil increases heat dissipation to improve power handling, reliability, and longevity. These engineering features work together to create a tweeter that is not only compact, but is also built to last.

In addition, the cast aluminum faceplate offers robust structural support and helps to reduce vibrations that can affect sound quality. A protective grill is included, safeguarding the delicate diaphragm from damage, making the CF18N-4 a practical choice for various environments, including mobile and high-performance home audio setups.

Overall, Dayton Audio's CF18N-4 tweeter is a fusion of advanced technology and user-focused design, ideal for audiophiles, casual listeners, and anyone seeking exceptional sound in a compact package.
