Evaluation sets

Ananke

Adap is optimised as a tweeter with high SPL above resonance. It has a higher resonance frequency than Achelous and due to its higher Q-factor the maximum SPL can be reached.

Amalthea and Carme

Achelous provides higher excursion and more damping ideal for in-ear designs. In free-field, the resonance is lower than Adap, which allows a lower cross over frequency.
