Meyer Sound Acheron Designer Loudspeaker for Cinema Applications – Remote Monitor System – 3-Pin XLR
Meyer Sound Acheron Designer Screen Channel Loudspeaker for Cinema Applications with Remote Monitoring System and 3-Pin XLR
The Acheron Designer uses the same patent pending horn technology and high-frequency compression driver as the other Acheron models, delivering the same 38 Hz to 17 kHz frequency response. This consistency of fidelity between Acheron models ensures that soundtracks monitored with the Acheron Designer translate accurately when played back in larger rooms with the Acheron 100, Acheron 80, Acheron Studio, or other calibrated cinema system.
Features:
- High peak power output with ultralow distortion
- Exceptional fidelity and extended high frequency performance
- Constant-Q horn yields uniform response throughout coverage area
- Extraordinarily flat amplitude and phase response for tonal accuracy
- Seamless integration with HMS-10 surround loudspeakers and X-800C subwoofer
