HK Audio L SUB 1200 - 2x10” Passive PA Subwoofer with Multi-Layer Birch Enclosure

HK Audio L SUB 1200 – 2x10” Passive PA Subwoofer with Multi-Layer Birch Enclosure

The HK Audio L SUB 1200 is a compact and lightweight passive subwoofer designed to deliver fast, controlled bass in professional sound reinforcement systems. Its multi-layer birch enclosure maximizes rigidity and reduces resonance, while the 2x10" loading configuration delivers a highly musical punch with excellent transient definition. Designed to integrate with the LINEAR 5 series, it is also ideal for combining with the L SUB 1200 A (active version) to create balanced and easy-to-deploy 2.2 stacks or configurations.

With 600 W RMS power handling, 101 dB sensitivity (1 W/1 m) , and 8 Ω nominal impedance , the L SUB 1200 delivers efficient performance and a response down to 38 Hz (−10 dB) , with a maximum SPL of 130 dB (10% THD). 2 × Speakon NL4 connectivity simplifies cabling and linking, and two M20 sockets allow mounting of satellite bars or dual-bar solutions for tight stacks. Four handles facilitate daily handling for touring and rental use, and a metal grille with black acoustic foam protects the drivers during transport and intensive use.

Product benefits

• Defined, fast bass: The 2 × 10” format provides punch and articulation ideal for live music and DJs.
• Efficiency and control: high sensitivity (101 dB) for higher level with less amplification power.
• Flexible configurations: dual M20 socket for mounting one or two satellites and creating compact 2.1 or 2.2 systems.
• Touring construction: birch enclosure, steel grille, and four handles for intensive use in rentals and events.

Use cases

• Low-frequency reinforcement in portable PA with LINEAR 5 speakers in venues and corporate events.
• 2.1/2.2 systems combining L SUB 1200 passive with L SUB 1200 A.
• Fixed installations in clubs, auditoriums and multipurpose spaces that require controlled bass.

Frequently Asked Questions

• Does it need a power amp? Yes. Being passive (8 Ω, 600 W RMS), it requires external amplification and processing/crossover.
• Can a satellite be mounted on top? Yes. It has two M20 sockets for speaker bars.
• What's the connectivity? 2 × Speakon NL4 for input and connection to another sub (impedance-matched).
