HK Audio PR:O 12M - 12”/1” Passive Stage Monitor with 60° × 40° Coverage

HK Audio PR:O 12M – 12”/1” Passive Stage Monitor with 60° × 40° Coverage

The HK Audio PR:O 12M is a 2-way passive stage wedge designed to deliver clear and powerful live monitoring. Featuring a 12-inch woofer/midrange driver and a 1-inch tweeter driver mounted on a 60° x 40° constant directivity horn, it delivers balanced vocal and instrument reproduction with enough pressure for demanding stages. Its 30° monitor-angled MDF enclosure with black acrylic enamel finish ensures durability and a professional aesthetic, while two integrated handles facilitate everyday handling.

The PR:O 12M handles 400 W RMS into 8 Ω (up to 1,200 W peak ), achieves a maximum level of 128 dB and offers a sensitivity of 104 dB (1 W/1 m) . Its 2 kHz passive crossover with 12 dB/octave slopes and dynamic protection for the HF driver ensures reliability even at high working levels. It integrates two Speakon NL4 connectors (input and output in parallel) for fast and robust wiring on tour or in installations.

Main features

Product benefits

• Stage definition: 60° × 40° directivity that focuses the mix towards the performer and reduces leakage to the rest of the stage.
• High-volume reliability: dynamic tweeter protection and optimized passive crossover.
• Agile operation: two Speakons in parallel for connecting monitors and quick assembly.
• Sturdy construction: Wooden (MDF) cabinet with a durable finish and foam grille to protect components.

Use cases

• Monitoring vocals, guitars, keyboards, and backing tracks on stage at venues, theaters, and local festivals.
• Portable sound systems for bands and rental companies that require durable monitors.
• Fixed installations in cultural centers, schools and houses of worship.

Frequently Asked Questions

• Does it need a power amp? Yes, it's an 8 Ω passive monitor; it uses a power amp rated at 400 W RMS per channel with peak headroom.
• Can I daisy-chain multiple monitors? Yes, using the Thru Speakon connector in parallel.
• Can it be used as a front-of-house speaker? It's a dedicated wedge monitor; for primary use, consider the full-range PR:O models.
