L-Acoustics | K2 - 3-way full-range active enclosure

The L-Acoustics K2 is a full-range, 3-way active line source element for large-scale sound reinforcement. It delivers a bandwidth of 35 Hz to 20 kHz and a peak SPL of up to 147 dB, with Panflex technology for adjustable horizontal coverage. The K2 offers the sonic character of the K1 in a lighter and more flexible 56 kg enclosure, which makes it ideal for touring productions, festivals, sports events and large venues.

Powerful full-range performance

The K2 is a three-way, quad-amplified loudspeaker with two 12 inch low-frequency drivers, four 6.5 inch mid-range drivers and two high-frequency compression drivers on dedicated waveguides. It reaches down to 35 Hz without a subwoofer and delivers a very high output for its size, giving large audiences a full, clear and impactful sound from the front row to the back of the venue.

Panflex: choose your horizontal coverage

With Panflex, a single K2 enclosure can offer four horizontal directivity patterns: 70° or 110° symmetric, or 90° asymmetric on either side. Combined with a wide choice of inter-element angles, you can match the array precisely to the audience area. This results in an even SPL distribution and less sound spill onto walls, balconies or neighbouring areas.

A true WST line source

The K2 meets the Wavefront Sculpture Technology (WST) criteria, so an array of K2 enclosures behaves as a coherent line source with a smooth tonal response and no secondary lobes over the full frequency range. The vertical coverage is shaped by the number of enclosures and by the inter-element angles, which range from 0.25° to 10°.

Efficient to rig and transport

The K2 integrates a captive four-point rigging system with visual safety checks, plus handles on both sides. This makes deployment fast and secure, and a range of rigging and transport accessories helps with storage and truck loading. At 56 kg, it offers an outstanding performance-to-weight ratio.

Typical applications

• National and international touring productions
• Festivals and open-air events
• Stadiums, arenas and sports venues
• Large theaters, concert halls and auditoriums
• High-end fixed installations

Pair it with

The K2 is quad-amplified by an L-Acoustics amplified controller such as the LA4X, LA8 or LA12X, and can be powered from the LA-RAK II touring rack. For extra low-frequency impact or throw, combine it with the K1-SB flown subwoofer, or add the SB28 for extended low-frequency performance.
