Identity and core specifications are documented; some historical fields remain unavailable.

Tony Andrews's Festival System combined folded-horn bass with horn-loaded mid and high sections, built for Glastonbury and other UK festivals in the mid-1970s. It used the second generation of his slender 'Turbo' phase device mounted in front of the midrange cones. Its success led Andrews to found Turbosound in 1978.
