A 26 x 36 mm ribbon tweeter is responsible for the high-frequency range in the model, inside of which there is a folded accordion diaphragm with sides of 13.3 x 4.4 cm. This driver is activated above the frequency of 2,600 Hz. The next segment from 2,600 Hz and below is voiced by a mid-frequency driver with an aluminum diffuser with a diameter of 133 mm mounted on a molded polymer basket. The exact same driver runs at bass below 500 Hz, and it can withstand solid power thanks to its wide, rigid suspension and metal diffuser.
