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.
