In order to undertake research into 3D audio reproduction systems, it was necessary to install a flexible loudspeaker rig into the ITU-R BS 1116 standard listening room at the University of Surrey. Using a mixture of aluminum truss and tube, a method for mounting loudspeakers in a manner that allows a wide range of layouts was created. As an example configuration, an installed 22.2 system is described. The method used to undertake bass management of this system, as well as methods to align the time of arrival, level, and frequency response of each channel are described. The resulting configuration is compared to the requirements of the ITU-R BS 1116 standard.
