The maximum peak sound pressure level should be 131 dB, measured with pink noise at a distance of 1 m, under half-space conditions and with a crest factor of 6. The loudspeaker cabinet should be made of birch multiplex and sealed with a weather and moisture resistant polyurea coating (PU). The front of the loudspeaker should be equipped with a ball-proof protective grille, which is backed with acoustically neutral foam. Its physical dimensions should be 152 mm in width, 758 mm in height and 214 mm in depth. The weight of the loudspeaker should be 13.2 kg. The loudspeaker should have an integrated quick connector system with which special accessories can be mounted.
