HK Audio PR:O 12 - 2-way passive full-range system (12”/1”) with 60° × 40° directivity

HK Audio PR:O 12 – 2-way passive full-range system (12”/1”) with 60° × 40° directivity

The HK Audio PR:O 12 is a passive PA enclosure in a classic 12”/1” format that delivers balanced sound and great voice intelligibility at high SPLs. Its bass-reflex design combines a 12” woofer for low/midrange and a 1” driver coupled with a 60° × 40° waveguide, achieving controlled and homogeneous coverage on stages, halls and events. The MDF cabinet with a black acrylic enamel finish integrates DuoTilt 3°/7° for beam steering when pole-mounted, three M8 rigging points and two handles for comfortable transport. In addition, it is acoustically adapted to combine with the PR:O 18 S or PR:O 210 S subwoofers when greater low frequency extension is required.
