L-Acoustics reveals full-range K3 line source system

L-Acoustics K3 line array

L-Acoustics has completed its K Series range with the introduction of K3, the manufacturer’s smallest full-range enclosure, designed to deliver audio for mid-size events with audiences ranging from 1,000 to 10,000. K3 provides full-range bandwidth, without the need for a flown companion subwoofer.

Providing the full-range L-Acoustics contour from an enclosure that is 33% smaller than K2 and weighing only 43 kg (95 lbs), K3 is suitable for applications that require power and bandwidth from a small form factor, including mid-size tours, festivals, corporate events, religious services and other productions. Dimensioned to keep sightlines clear, K3 integrates easily into venues with space restrictions.

The new two-way active WST enclosure includes optimised mechanical design for reduced weight, laminar vents for linear low frequency response, and easy rigging.

K3 also features L-Acoustics Panflex technology, which provides sound designers with quick access to a choice of four horizontal directivity patterns: 70° or 110° symmetrical or 90° asymmetrical on either side. With Panflex and inter-element angles ranging from 0° to 10°, K3 line source coverage can be tailored to fit any audience geometry.

Equipped with the L-Acoustics signature DOSC waveguide for long-throw capability (>35 m/100 ft), K3 boasts an exceptional bandwidth of 42 Hz to 20 kHz (-10 dB, 70° directivity) and maximum SPL of 143 dB. Without needing a dedicated subwoofer, K3 can be used as the main system for vocal and music reinforcement in most applications, or as a complement to K1 or K2 as outfills or delays. When deployed with KS28 subwoofers, K3 excels as a compact main system for demanding live events.

One LA12X amplified controller can power up to six K3, meaning that a single LA-RAK AVB unit can drive up to 18 K3.

With the first K3 production units already shipping to customers, L-Acoustics will deliver K3i, a fixed install version, in 2021. K3i will be suitable for an even larger range of applications using a distributed approach.
