CBEAM Complex Structural Ratings
AGCD Complex Structural-Strength Ratings
The AGCD is an adapter grid that allows XLVC loudspeaker systems (XLD281) to be rigged to
XLC loudspeaker systems (XLC127+, XLC215 or XLC118) in the same column.
The structural strength of a column of XLVC and XLC loudspeakers linked together using an
AGCD is a function of the strength of the adapter grid assembly, the front and back rigging
attachment to the XLVC and XLC enclosures, the strength of all of the quick-release attachment
pins, the loudspeaker array configuration and the vertical tilt angle of the grid. This is a complex
mechanical system, where the strength of the overall system is determined by the strength of the
weakest component in the system.
The Electro-Voice engineers have designed the AGCD adapter grid to be stronger than either the
XLVC or XLC loudspeaker systems over the entire mechanical operating range of the loudspeaker
systems. This makes the structural analysis of the overall system (adapter grid and loudspeaker
enclosures) much easier because the structural rating of the entire mechanical system will be
determined solely by the structural strength of the loudspeaker systems.
