Meyer Sound Acheron Studio Screen Channel Loudspeaker for Cinema Applications with Yoke / 3-Pin XLR

The Acheron Studio uses the same horn technology (patent pending) developed for the Acheron 80. Designed specifically for cinema use, the horn features a very soft roll-off outside its extremely well behaved 80-degree horizontal by 50-degree vertical coverage pattern. The horn is fixed within the enclosure to ensure an accurate acoustic crossover, phase response, and an incredibly consistent vertical pattern. The 580 Hz crossover point places most of the dialog in the horn, which is ideal for cinema applications.

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
