HK Audio L5 115 F - 2-way full-range passive enclosure with rotatable asymmetrical horn

HK Audio LINEAR 5 L5 115 F – 2-way full-range passive enclosure with rotatable asymmetric horn

The HK Audio L5 115 F is a 2-way passive loudspeaker combining a 15” woofer (3” voice coil) and a 1” compression driver (1.75” diaphragm) in a low-resonance multi-ply MDF/birch hybrid enclosure. Designed for professional sound reinforcement, DJs and live performances, it can be used as a stand-alone enclosure or integrated with other LINEAR 5 Series systems and LINEAR SUB subwoofers. Its asymmetrical rotatable horn offers 60°–90° (H) × 55° (V) coverage that opens up the front row and concentrates energy to the back, achieving a balanced projection throughout the venue.

The bass-reflex architecture and transducer engineering deliver a wide frequency response — 62 Hz – 18 kHz (−6 dB) / 52 Hz – 20 kHz (−10 dB) — with 600 W RMS (1200 W program / 2400 W peak) power handling . With a peak SPL of 135 dB , sensitivity of 103 dB (1 W/1 m) , and a passive crossover at 1.7 kHz (12 dB/oct) with PTC high-frequency protection , the L5 115 F delivers authoritative, reliable performance in rental, touring, and installation settings. Connectivity includes two × Speakon NL4 (input and link on 1+/1- ), while mounting is simplified with DuoTilt 3°/7° and three M8 mounting points . The set is completed with a steel grille backed with acoustic foam , 2 MultiGrip handles and a black acrylic enamel finish that withstands intensive use.

Product benefits

• Optimized Coverage: The asymmetrical trumpet opens in the front row and focuses on the back for improved range and clarity.
• High performance with less effort: high sensitivity and 600 W RMS translate into high power with moderate amplification.
• Quick deployment: DuoTilt makes beam aiming easy without complex hardware; Speakon connectors for clean wiring.
• Touring reliability: PTC protection and multi-layer woodwork prepared for intensive use.

Use cases

• Main PA in venues, corporate events and places of worship.
• Live music and DJ reinforcement with LINEAR SUB subwoofers.
• Fixed installations that require a controlled pattern and high pressure.

Frequently Asked Questions

• Does it need a power amp? Yes, it's a passive enclosure; use a suitable amp (8 Ω) and external processing/crossover if you're working with a subwoofer.
• Can I reorient the cover? Yes, the asymmetrical diffuser can be rotated to adapt to the position of the cabinet.
• How do I install it on a bar? Use the DuoTilt 3°/7° to adjust the angle toward the audience.
