110 / 112 / 115 ROTATABLE HORN
The ARCHON series 110 / 112 / 115 models feature a constant directivity rotatable horn.
The constant directivity horn permits getting a response whose frequency is almost constant in every direction covered by horn operation
and a balanced sound timbre emission over the whole coverage angle.
Horn rotation changes the dispersion angle so as to use the speakers in horizontal position or when they are aligned in an array.
To change horn coverage angle:
> Remove the 4 screws fixing the front mesh and remove it.
> Unscrew horn fixing screws and rotate it to the desired position (never extract the horn unit from the speaker).
> Tighten the horn fixing screws again and place the mesh back.
