4" | 41FR
Ferrite Full-Range
Key features:
- Very good performance at affordable price
- Excellent HF extension
- Array applications, 2-way systems, can be used without HF unit
Design notes:
41FR is ferrite based mid-woofer, developed for applications where small size mid-woofer is required. This version was developed with extended HF response and in some cases could be used as full-range driver. Yet, this driver delivers very good performance low frequency range as well.
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.
