OPERA P15 is a passive speaker studied for the sound reinforcement of medium to big environments; it offers the possibility to obtain high sound pressures. The speaker is equipped with 15″ woofer (3″ voice coil) and 1″ compression driver (1.75″  voice  coil) loaded with 80°/65°x60° asymmetric horn.

The speaker is made in reinforced polypropylene and acoustic components are protected by metal grille with internal foam which protect them from bad weather.
