L-Acoustics to Release New L Series Loudspeaker With Progressive Ultra-Dense Line Source Technology


L-Acoustics announced the new L Series with patented Progressive Ultra-Dense Line Source (PULS) technology. L Series comprises two elements that are designed to work together or on their own: L2 above and L2D below. One L2 or L2D element provides the same contour as four K2 elements in a format that is 46% smaller and 40% lighter. The audio benefits of L Series encompass industry-leading SPL per size, unparalleled consistency over the audience area, and improved rejection everywhere else. Accompanying the audio benefits, L Series revolutionizes deployment with a smaller, lighter footprint that reduces truck space and requires fewer elements, cutting the number of actions needed to load in and out.

The power density of the new L Series is unprecedented. Each element contains eight three-inch high-frequency drivers with eight ten-inch low-frequency drivers, complemented by four side-loaded 12-inch drivers with front and back exits to deliver efficient, high-precision broadband coverage with a choice of cardioid or supercardioid patterns. L Series 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. Each L2 element includes four Panflex modules, while L2D contains two Panflex modules on the top elements, and two fixed L-Fins progressing from 110° to 140° on the bottom elements.

The operating efficiencies of L Series originate from its shape. With no inter-element angles, a pin-less auto-lock rigging system, and a single cable connector, repetitive load-in/out actions are drastically diminished. This creates a set-up environment that reduces errors and leads to a stunning three-fold decrease in loading time versus a similar K2 configuration or up to five times faster than Kara II.

Here’s a video of the actual launch with a demo:

L Series is just as impactful on the environment as it is on deployment. Starting with material savings—56% less paint, 30% less wood, and 60% less steel—L Series is frugal in resources. Clocking in at 30% less volume and 25% less weight as compared to an equivalent line source array, L Series is also frugal in truck space and consequently in fuel consumption.

Adding to system efficiency, L Series is driven by the new LA7.16 high-resolution touring amplified controller, which supports L2 and L2D with 16 channels of high-power amplification and processing. LA7.16 comes in a new LA-RAK III touring rack offering 48 channels of amplification in a Milan AVB-ready package with more than 60,000 watts of power in 9U. Leveraging the high-resolution amplification of LA7.16 and the advanced Autosolver tools, L Series output can be perfectly modulated to achieve results that are impossible with traditional line array technology.

With L Series, L-Acoustics also introduces the new Clamp1000, which can carry up to four L2/L2D. It can also be used with Kara II, K3, or K2, supporting up to 16 K2. Using Clamp1000, users can rotate a flown line array from the ground, drastically saving set-up time and the number of motors needed.
