ND850-1,4 er en high-perfomance 3" diaphragm compression-driver med en 1,4" exit-throat. Diafragmaen er præcisionsformet fra 0,05 mm tykt titanium. Ophænget er baseret på et udluftet design som giver lavere forvrængning. Voice-coil-konstruktionen er designet ved brug af kapton-former under høje temperaturer.
