Tilting the Waveguide
The 4895's Multiband Waveguide within the aluminum SpaceFrame has three orientations. In its
upright position the Waveguide is parallel to the front of the SpaceFrame, with the drivers aiming horizontally.
By releasing the plunger pin on the tilting mechanism at, the Waveguide pivots to two other locked positions,
angling it back either 15 or 7.5 degrees vertically. This helps the top or bottom speakers in an array achieve the
correct angle of coverage while constructing vertically connected columns of Spaceframes. Tilting the waveguide
back causes the magazine to extend past the back of the Spaceframe.

CAUTION! To avoid accident or injury, support the weight of the Waveguide and Magazine
while releasing its lock. Care should be taken to keep fingers outside the Spaceframe and clear
of the tilting mechanism. The combined weight of the waveguide and magazine is 100 lbs.
(45 kg).
Ground-stacked Array Construction
Speaker arrays that are suspended in mid-air enjoy a significant advantage in their ability to cover a
listening area evenly from front to back. However, it is not possible to suspend speaker arrays in every situation,
due to various considerations and limitations. Speaker arrays can be deck-stacked on stage wings at the
downstage corners of the stage, or raised above the plane of the stage by means of scaffolding, risers or additional
speakers used to increase the height of the stacked speakers.
Ground-supported arrays typically place sub-woofers on the bottom row and stack full range speakers
