Overview

Beyma 8CX300Nd/N 8" Coaxial Neo Loudspeaker 8+8 Ohm

8CX300Nd/N 8" Coaxial Neo Loudspeaker 8+8 Ohm

The 8CX300Nd/N's substantial power handling capabilities and high sensitivity enable it to deliver clear and dynamic sound output, making it suitable for demanding audio applications. The 2.5" voice coil in the low-frequency driver and the 1.75" voice coil in the high-frequency driver enhance thermal stability, contributing to consistent performance over time. The inclusion of a shorting cap in the magnetic circuit extends the frequency response and reduces distortion, ensuring accurate sound reproduction. The weatherproof carbon fiber-loaded paper cone offers enhanced durability and reliability, even in challenging environmental conditions. The Santoprene surround further enhances mechanical stability, maintaining consistent performance. The PM4 diaphragm in the high-frequency driver improves sound quality, while the 70º conical coverage pattern provides controlled dispersion, making it ideal for applications requiring precise directivity. Optimized for studio monitors, compact PA systems, and high-fidelity installations, this coaxial transducer offers versatility and exceptional performance for professional audio setups.​

​Beyma's Research and Development department collaborates closely with the Technical Office to conduct practical experiments that demonstrate and share acquired knowledge.

A notable outcome of this research is the development of the PM4 diaphragm, which incorporates a high-tech polymer previously unused in audio applications.

This innovation results in a stronger bond between the dome and the voice coil former, enhancing performance under high power and prolonged use. ​

Beymas believes that the PM4 diaphragm offers a more natural sound compared to other polyester materials.
