Why it mattered

  1. 01

    It offered theatre-horn bass efficiency in a box a small crew could carry.

  2. 02

    It replaced repurposed cinema cabinets like the A7 in many 1970s touring rigs.

  3. 03

    Kennedy's FOH survey dates Community's glass-fibre horns, including the Leviathan bass horn, to 1974 and credits them with demonstrating composite materials in long-throw stadium installations.
