The Diva®Acoustical Shell can be used for a variety of performance groups such as orchestra
performance, single performance recitals, etc. Tower and Ceiling Panel arrangements can be easily
changed.
The number of Towers and Ceiling Panels used, how they overlap, and the performance angles can be
adjusted for different effects. Some Towers have one or two doors for easy stage access.

•Towers are stored in a nested position off-stage with Wing Panels folded.
•Ceiling Panel Rows are rotated into the vertical position and stored in the loft area.
The sequence for setting up the Diva Acoustical Shell is as follows.
1. Lower the Ceiling Panels first.
a. Place the Ceiling Panels in a position where the Panels can be rotated from the Storage
Position to the Performance Position, then, lift the Ceiling Panel Rows high enough to move
Towers across the stage.
15' Time can be saved if Tower positions are marked on the stage floor.
b. Move the Towers with a Wheeled Mover or an Air Transporter to the performance position and
open the Wing Panels to the Performance position.
c. If the Ceiling Panel Rows have tapered ends, lower each row to a position slightly below the top
of the adjacent Side Towers.
d. If the Side Tower has a tapered top and the edge of the Ceiling Panel Row extends outside of
the Tower, lower the Ceiling Panel Row to a position 4” to 6” above the Tower.
