Product Overview
The Meyer Sound STB-ACHERON is a stacking bracket kit that allows an ACHERON 80 or ACHERON 100 screen channel loudspeaker to be mounted on top of an ACHERON-LF screen channel subwoofer. It enables uptilt or downtilt aiming so the screen channel can be positioned correctly behind a perforated screen. The kit uses the 3/8-inch threaded points provided on the cabinet corners of the ACHERON loudspeakers. It is an installation accessory for ACHERON cinema systems.
Product Description

Because the ACHERON loudspeakers and the ACHERON-LF share the same rectangular footprint, the STB-ACHERON stacking bracket allows the screen channel to be coupled directly on top of the subwoofer, forming an aligned column of low-frequency drivers. The brackets attach to the 3/8-inch threaded points on the side corners of the cabinets and support uptilt or downtilt to aim the system at the audience. This stacking bracket is intended for use with the ACHERON-LF screen channel subwoofer together with the ACHERON-100 or ACHERON-80. Additional Meyer Sound cinema products are available in the Meyer Sound collection.
