User manual ELECTRO-VOICE 927S DATASHEET

[. . . ] Using VBS (Vertical Beam Shaping) technology this benefit can be increased by another 20° to 30° of pattern control above 300 Hz. VBS uses filters to overlap the LF section bandpass with mid-bass bandpass. [. . . ] Frequency response onaxis is unaffected, while gain before feedback is increased by 10 to 15 dB for microphones located under the loudspeaker. The DL10X 10-inch mid-bass driver features RMDTM and is coupled to a rotatable 100° x 60° vertical horn. The high-frequency system uses an ND6-16 largeformat compression driver with a rotatable 100° x 60° horn. It is mounted within the upper woofer enclosure to provide a compact vertical size. The Xi-1123A/106 is ideally suited for high-level, high-fidelity applications. The system is particularly suited where extended vertical polar control is necessary. The loudspeaker shall be constructed of 18-mm, 13-ply birch and shall be trapezoidal in shape. The grille shall be constructed from 16 GA powder-coated steel backed by acoustically transparent fabric. The system shall be capable of very-high level operation with a band width of 53 to 19, 000 Hz. The system dimensions shall be 458 mm (18. 05 inches) wide by 801 mm (31. 54 inches) high by 473 mm (18. 64 inches) deep. The system shall employ flying hardware of a "track" style and have two tracks on the enclosure top and two tracks on the enclosure bottom.
