Compared to a traditional single driver approach, the advantage of a dual driver system is the ability to handle bass and mid to high frequencies separately—resulting in a more immersive audio experience with the music, movies and games you love.
By themselves, both types of drivers have their own limitations. Dynamic drivers of lower quality can be prone to audio distortion at higher volumes, while balanced armature drivers lack bass response because they don’t generate sound by displacing air.
When paired together however, these limitations are offset to provide a fuller range of audio with superior clarity that neither driver can achieve alone.
