NTR10-2520D 250W 8ohm LF Neodimio

Caratteristiche

- 10" neodymium mid/bass unit offers 250Wrms (AES standard) power handling and 96dB sensitivity

- 2.5" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing sensitivity loss through thermal compression

- "M-roll" surround provides progressive excursion control, yielding a smooth response even at extremes of frequency range

- Extremely lightweight design combined with a highly efficient magnet assembly results in exceptional power-to-weight ratio

- Intelligent heat management in both chassis and magnet assembly design further minimises distortion
