HK Audio L SUB 2000 - 2x12” Passive PA Subwoofer with Multi-Layer Birch Enclosure

HK Audio L SUB 2000 – 2x12” Passive PA Subwoofer with Multi-Layer Birch Enclosure

The HK Audio L SUB 2000 is a passive subwoofer system combining two 12” speakers in a compact and robust multi-ply birch enclosure. Designed to integrate seamlessly with LINEAR 5 Series systems, it delivers bass response down to 39 Hz (-10 dB) with a maximum SPL of 135 dB (peak at 10% THD) , delivering punch and control in live music, DJ and corporate event applications. With 700 W RMS power handling, 104 dB sensitivity (1 W/1 m) , and 4 Ω nominal impedance , the L SUB 2000 performs with efficiency and headroom in portable systems or fixed installations.

Its 2 × Speakon NL4 connectivity simplifies cabling and linking between enclosures. It includes an M20 socket for a satellite bar and four handles for easy assembly and transport. The metal grille with acoustic foam protects the transducers, while the black acrylic enamel finish ensures durability against daily use. With dimensions of 51 × 81 × 61 cm and a weight of 45.6 kg , it balances acoustic volume, stability, and portability for 2.1 stacks or larger arrays alongside the LINEAR 5 family.

Frequently Asked Questions

• Does it need a power amp? Yes. Being passive (4 Ω, 700 W RMS), it requires external amplification and processing/crossover.
• Can I link multiple subwoofers? Yes, the two Speakon NL4s allow input and link to another sub (depending on the total power/impedance).
• Can a satellite be mounted on top? Yes, it includes an M20 speaker bar socket .
