Celestion NTR10-2520D 8 ohm 10" 250W Neodymium Pro Audio Woofer T5638

Features Include

• 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 minimizes distortion
