Every Amphion model delivers..

Point-source sound

Lowering the crossover point allows the speakers to operate in point-source manner. This leads to industry leading phase coherence and pinpoint imaging.


Time-aligned drivers

Timing properties between the various drivers are improved as the waveguide aligns the voice coils of the tweeter and the midwoofer.


Less is more

Pushing the acoustics leads to electrical simplicity. Advanced acoustic engineering simplifies the signal path, which increases resolution and transparency.


Unrivalled midrange clarity

Exceptional naturalness and purity makes listening a joy. The nuances of human voice and instruments are presented in their full glory.


Room-wide sweet spot

Thanks to even dispersion, enjoyment is not limited to a single seat. Everyone in the room can share the experience equally.


Low volume, high intensity

Easy to place and well-performing even under challenging acoustics. Clear and memorable even on lower listening volumes.
