3.5" | 35FR
Ferrite Full-Range
Key features:
- Mighty driver delivering the highest performance
- Very good LF extension, large peak to peak cone displacement
Design notes:
35FR was developed as full-range ferrite magnet driver. It has an excellent HF extension and provides extended level of LF performance.
The driver was designed for usage in sealed speaker systems. It could be in column speakers, 2-way or 1-way speakers. It is also possible design a speaker system with a passive radiator to further extend the low frequency range.
Voice coil is wound with copper hi temperature wire directly on the aluminum former, ensuring good power handling and high temperature stability.
This driver brings good balance between performance and cost.
Depending on intended usage, we can deliver the driver either as 4 or 8 ohm version.
