HK Audio PR:O 8 - 2-way passive full-range system (8”/1”) with 80° × 80° directivity

HK Audio PR:O 8 – 2-way passive full-range system (8”/1”) with 80° × 80° directivity

The HK Audio PR:O 8 is a compact 2-way passive loudspeaker that delivers balanced sound with high voice intelligibility and surprising sound pressure for its size. Its bass-reflex architecture combines an 8" woofer with a 1" driver in an 80° × 80° constant directivity horn, achieving homogeneous coverage in venues, stages and events. The MDF enclosure with a black acrylic enamel finish integrates the MonoTilt 3° for beam steering when pole-mounted, as well as three M8 suspension points and two handles for easy transport. It is acoustically tuned to work with the PR:O 18 S and PR:O 210 S subwoofers when greater low-frequency extension is required.
