Epic bass comes as standard with the 21-inch NTR21-5010JD. With advanced technology including a finite-element-analyisis optimised neodymium motor and 5-inch high temperature Inside/Outside voice coil, this subwoofer delivers a monster 1600Wrms (3200W continuous) power handling. But that’s only half the story! The NTR21’s neo magent and super-efficient design means that the speaker weighs in at only 12.8kg (28lb), without any compromise to its collossal low frequency response. Whether you’re loading a vented (reflex), scoop or horn-loaded bass cab, build a better sound with Celestion’s robust and lightweight NTR21-5010JD.
