ND44 is the budget version of  ND45.

It is 1” high frequency neodymium compression driver, that incorporates new phase plug, new dome with vented suspension and copper inductance ring, which improve sound characteristic and ensure very low distortion at high sound levels.

The smooth impedance response in crossover region ensures perfect work with passive crossovers

The reduced weight and size make it preferable for high quality compact 2 way and line array boxes. The voice coil assembly is easily field replaceable without soldering.
