4" | 4FR
Ferrite Full-Range
Key features:
- Optimized full-range performance
- Good low frequency behavior
- Affordable design
Design notes:
- 4FR ferrite based mid-woofer was developed for applications where small size mid-woofer is required. Low resonant frequency and large cone excursion delivers seizable amounts of low frequencies. Yet, this driver delivers very good
- performance in mid-high frequency range. Our engineers have chosen lightweight, yet strong, paper cone with rubber surround. Cone optimized shape brings remarkable strength of the piston and greatly improves harmonic distortion
- artifacts. Overall this model delivers very good performance and is well balanced between performance - cost.
