Celestion NTR21-5010JD 21" Neo 8ohm Subwoofer Speaker

Description

Celestion NTR21 5010JD 21" 1600 watt Neo Subwoofer

The Celestion NTR 21" neodymium subwoofer offers 1600Wrms (AES standard) power handling
and 98dB sensitivity
5" high temperature Inside/Outside voice coil efficiently dissipates heat, preventing
sensitivity loss through thermal compression
Double suspension and a "multi-roll" surround provide exceptional linearity at
extremes of cone excursion
Rigid lightweight carbon fibre loaded cone delivers improved performance and
faster response
Intelligent heat management in both chassis and magnet assembly design
further minimizes distortion.

Designed & manufactured in the UK.
