Amphion Helium520C Loudspeaker
Best center channel for audiophiles building a cohesive home theater system.
This center channel prioritizes phase coherence and a massive soundstage by moving the crossover point outside the critical hearing range. While its passive radiator design demands careful placement to avoid boominess, the result is a level of vocal clarity and studio-grade resolution that few home theater setups ever achieve.
