NTR10-2520D
• 10" neodymium mid/bass unit offers 250Wrms (AES)
continuous 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
