Sub250_vHE has been designed to reproduce powerful bass impact and every single detail in low frequency. It integrates several innovation to keep THD below 1% from 25Hz to 300Hz (free air, playing 90dB at 1m).

Suspension are fully balanced by reinforced NBR surround and dual dynamiK spiders, keeping unchanged resonance frequency value, whatever the cone excursion (+/-12mm).

The motor structure uses 2x NdFeB magnets, 2x Aluminum rings and advanced pole pieces design to get strong magnetic field and cool the voice coil. This one is built on Ø82mm glass fiber former, made of only 2 layers (1inner / 1outer) to minimize the inductance value and the related modulation.
