2.5" | 25NFR
Neodymium Full-Range
Neodymium Full-Range
Neodymium Full-Range Neodymium Full-Range
Key features:
  • Full-range FREQUENCY RESPONSE
  • A very small form factor
  • Optimized frequency response
Design notes:
25NFR was designed around neodymium ring magnet. The magnetic structure delivers very high level of magnetic force, while generating minimum amount of modulation distortion. The lightweight, yet strong, paper cone with attached rubber surround was designed and optimized to deliver the highest level of performance in full-range applications. This speaker finds its best application in columns or multi-way Hi-Fi products. Due to its excellent HF response, further usage of HF units is not required. The small form-factor allows this product to be used in space limited applications or portable products.
