L-Acoustics Debuts New Compact, Full-Range K3 Line Source Loudspeaker System

The two-way K3 provides the full-range L-Acoustics contour from an enclosure that is 33 percent smaller than K2 and with a weight of 95 lbs.

L-Acoustics rounds out its K Series with the introduction of K3, the manufacturer’s smallest full-range enclosure that’s designed to provide full-range bandwidth without the need for a flown companion subwoofer.

“K3 is ready for the events of today and tomorrow,” states L-Acoustics executive director of application design Florent Bernard. “Our design team created a dual-12-inch-based system with the form factor and price of a 10-inch design, without the inherent performance compromises of 10-inch loudspeakers. K3 offers long-throw, full-range performance in a compact, accessible package, tailor-made for small to mid-capacity events and venues that are the mainstay of most sound providers. It is a ‘no compromises’ tool, perfectly adapted to the current event landscape and, when paired with K1 and K2, is quickly and powerfully scalable for large-capacity events.”

K3 provides the full-range L-Acoustics contour from an enclosure that is 33 percent smaller than K2 and with a weight of 95 lbs (43 kg). The two-way active WST system incorporates an optimized mechanical design for reduced weight, laminar vents for linear low frequency response, and simplified rigging. It also includes L-Acoustics Panflex technology, designed to provide sound designers with quick access to a choice of four horizontal directivity patterns: 70 or 110 degrees symmetrical or 90 degrees asymmetrical on either side. With Panflex and inter-element angles ranging from 0 to 10 degrees, coverage can be tailored to the specific audience geometry.

K3 is also equipped with the L-Acoustics DOSC waveguide for long-throw capability (>35 meters/100 feet). Stated bandwidth is 42 Hz to 20 kHz (-10 dB, 70=degree directivity) and maximum SPL of 143 dB. Without a dedicated subwoofer, K3 can be used as the main system for vocal and music reinforcement in many applications, or as a complement to K1 or K2 as outfills or delays. When deployed with KS28 subwoofers, it forms a compact main system. One LA12X amplified controller can power up to six K3s, meaning that a single LA-RAK AVB unit can drive up to 18 K3s.

With the first production units already shipping to customers, L-Acoustics will deliver K3i, a fixed install version, in 2021. Go here for more specifics on the new L-Acoustics K3, and here’s the video of the global livestream product launch:
