The GEO S Array System is a professional rigging system, and should be handled with extreme care. GEO S850 and S830 loudspeakers are shipped from the factory with identical array assembly hardware. The GEO Array Assembly has three attachment points on each side. The points in the front connect each GEO cabinet to the adjacent enclosures above and below.
The angle between cabinets is set by attaching one end of the angle-setting bar to the proper hole on the angle-setting plate which extends beyond the rear of the cabinet. The GEO S Bumper is symmetrical, enabling you to use GEO loudspeakers in a left/right stereo configuration. The connection between the top GEO S enclosure and the bumper determines the left/right orientation for the entire array.
GEO Array & Deployment Facts
GEO S Technology in Horizontal Arrays
Do not think of GEO as only a vertical array system. Horizontal arrays of GEO loudspeakers have relatively high power (because of the narrow 30° horizontal array element) and wide front to back coverage of 80° to 120°.
Horizontal arrays deliver equal power to equal angles, with SPL decreasing as you move further back in the audience. Because they are limited to a single row (for a coherent wavefront without interference in the vertical plane), horizontal arrays deliver “equal power to equal angles” and suited for a special set of audience geometries such as stadium bowls, arena “exploded clusters”, opera-style theatres with multiple balcony levels and often as the centre cluster in a L-C-R system.
Horizontal arrays of GEO S830 cabinets provide exceptional control of horizontal coverage and, where the geometry is suitable, either GEO S or GEO T horizontal arrays will deliver a coherent wavefront in the midrange and high frequencies.
GEO S830 allows users to provide 30º increments of horizontal coverage as needed. Where the geometry is suitable, GEO arrays will deliver a coherent wavefront consisting of 30° tangent arcs that is more intelligible and reveals more musical detail than the incoherent sound produced by arrays using multiple conventional horns, which must be separated in space and time.
The GEO S830 is designed to array tangentially with adjacent S830 cabinets to provide a much more coherent wave front from an array of multiple cabinets than conventional arrayable cabinets Where the best fit to the geometry of the listening area is a single row of horizontally-arrayed speakers, GEO technology provides a coherent source of midrange and high frequency energy. This is because GEO wavesources produce a curved wavefront using hyperboloid acoustic mirrors instead of angled sidewalls.
A hyperboloid, a GEO wavesource exhibits dual sources: a real source and a virtual source. The GEO design process puts the virtual source behind the enclosure, and these virtual sources can be perfectly aligned.
