4" | 41NFR
Neodymium Full-range
Neodymium Full-range
Neodymium Full-range Neodymium Full-range
Key features:
  • Full-range FREQUENCY RESPONSE
  • Extended LF response
  • Front or rear mounting
Design notes:
41NFR was introduced as part of our new range of smaller transducers. The model is focusing on improvements in frequency response, both in LF and Mid-Freq. Powerful neodymium ring based magnetic structure delivers the highest levels of moving force onto the voice coil with minimum distortion artifacts. The cone and rubber surround were further FEM modeled and deliver incredible performance. 41NFR was designed for column speakers, micro line-array systems and two-way audio systems. Due to its good performance in high frequencies, this driver can be used without HF unit, which opens new opportunities for the system engineers to design compact, yet good sounding products. Our newly developed basket with typical REDCATT shapes, utilizes tall front EVA gasket and 1mm rear gasket. The driver can be thus mounted from both sides of the baffle.
