HK Audio L5 112 X - 2-way full-range passive enclosure (12” + 1” driver) with 60° × 40° rotatable horn

HK Audio L5 112 X – Compact 2-way passive full-range system

The HK Audio L5 112 X is a 2-way passive loudspeaker designed to deliver powerful, controlled sound reinforcement in a compact form factor. Featuring a 12" woofer/midrange driver and 1" compression driver (1.75" diaphragm), this model delivers up to 135 dB SPL peak, while maintaining a balanced response and precise directivity thanks to its 60° x 40° rotatable horn. Its hybrid wood (ply birch/MDF) enclosure with a multi-angle trapezoidal design and black acrylic paint finish reduces resonances and withstands intensive use in touring, installations and professional rentals.

Optimized for voice and music from 100 Hz (-6 dB), the L5 112 X performs reliably as a mid/high unit in combination with Linear series subwoofers (e.g., Linear Sub 2000) or as a low-feedback stage monitor, taking advantage of its 33° monitor bezel. The system features PTC treble protection, a high sensitivity of 104 dB (1 W/1 m), Speakon NL4 connectivity with 1± cabling, and a DuoTilt 3°/7° mount for precise tripod positioning. All this with 500 W RMS at 8 Ω and “Made in Germany” construction.

Main features

• 2-way passive speaker with 1 x 12" woofer (2.5" coil) + 1 x 1" compression driver (1.75" diaphragm).
• 135 dB SPL peak and 130 dB SPL average (EN 60268-21 measurement), high sound pressure with low distortion.
• Constant 60° x 40° rotating diffuser to adapt coverage vertically or horizontally.
• Frequency response: 100 Hz–18 kHz (-6 dB) / 72 Hz–19 kHz (-10 dB).
• Power: 500 W RMS / 1000 W program / up to 2000 W peak.
• Nominal impedance of 8 Ω and sensitivity of 104 dB (1 W/1 m).
• Hybrid birch ply/MDF enclosure with multi-angle trapezoidal design.
• Use as a stage monitor with a 33° angle and high gain before feedback.
• DuoTilt 3°/7° mounting and 3 M8 rigging points for secure installation.
• Connectivity: 2 x Speakon NL4 (input + parallel link, assignment 1±).
• 2mm steel grille with acoustic foam, integrated handles (1 MultiGrip + 1 SingleGrip).
• Compact dimensions of 37 x 67 x 30 cm and weight of 19.5 kg.

Product benefits

• True versatility : works as a mid/high top with subwoofer or as a low-feedback floor monitor.
• Controlled Coverage : The 60° x 40° rotating diffuser concentrates energy where it is needed and simplifies overlapping between boxes.
• Maximum efficiency : 104 dB sensitivity makes better use of the power of the amplifier and facilitates high levels with less demand.
• Professional construction : wooden enclosure, steel grille and acrylic paint resistant to intensive use and transport.
• Quick integration : DuoTilt and M8 points speed up mounting on a tripod, stand or fixed installation.
• HF protection : PTC circuit that adds safety to the treble motor against unexpected events.

Use cases

• PA reinforcement in small and medium formats, pairing with Linear subwoofers (e.g. Linear Sub 2000) for 2.1 / 2.2 systems.
• Stage monitor for bands, DJs and speech thanks to its 33° angle and high gain before feedback.
• Fixed installations in multipurpose rooms, theaters, clubs or churches with M8 rigging and controlled directivity.

Frequently Asked Questions

• Can I rotate the diffuser? Yes. The 60° x 40° horn can be rotated to adjust the coverage vertically or horizontally.
• How do I connect it? It has 2 x Speakon NL4 (parallel input and output) with 1+/1- assignment.
• Can it be used as a monitor? Yes. The 33° chamfer and narrow directivity allow for high pressure with low feedback.
• What amplification is it compatible with? Tuning sheets are available for Lab.gruppen IPX/IPD and Lake; the continuous power rating is 500 W at 8 Ω.

Construction and materials

The hybrid multi-ply birch/MDF enclosure, black acrylic enamel finish (RAL 9005), and 2 mm steel grille with acoustic foam provide durability and protection for the components. The 3°/7° DuoTilt system, three M8 mounting points, and two handles (MultiGrip + SingleGrip) facilitate transport and assembly, while the multi-angle trapezoidal design allows for stacking, freestanding, or monitor use without additional accessories.

System compatibility

The L5 112 X is tuned to operate as a mid/high unit from 100 Hz and pairs naturally with Linear series subwoofers (e.g., Linear Sub 2000) for extended low-end extension and punch. Presets and filter sheets for Lab.gruppen IPX/IPD and Lake platforms are provided, streamlining system alignment and protection in professional applications.
