This DA family tweeter features an 8 ohm 1.25 inch voice coil, with Corundum dome, large rear chamber for low resonant frequency, and a ferrite motor with heat sink. The large motor and rear chamber allow for robust power handling capacity. The protective grille can be removed for the highest possible performance, however the dome is very delicate so we recommend the grille is fitted in normal operation.
