Already on tour with Bruno Mars and Joker Xue, and on the stages of major music festivals, L1 and CS1 expand L-Acoustics L Series to set a new performance record for large-format line array systems with enhanced full-band coherence and integrated control<\/em> <\/em><\/p>\n\n\n\n

LOS ANGELES, CA – May 2026 – <\/strong>L-Acoustics today unveiled L1, the flagship of the L Series, and its companion cardioid subwoofer, CS1. Built on L-Acoustics patented Progressive Ultra-Dense Line Source (PULS) technology, L1 sets a new absolute reference for stadium sound systems that has already been entrusted to the world’s biggest stages. <\/p>\n\n\n\n

L1 has been deployed on Bruno Mars\u2019 The Romantic<\/em> tour with Clair Global, for Harry Styles Together, Together<\/em> tour with Solotech, and on Joker Xue\u2019s world tour with MRT, as well as a debut at the Brit Awards in London with Britannia Row, a Clair Global company. CS1 delivered the low end on the main stages of Coachella Valley Music and Arts Festival with RAT Sound, and Ultra Music Festival with Unreal-Systems\/AgorA. <\/p>\n\n\n\n

L1 and CS1 also mark their first permanent installation at the Hollywood Bowl, deployed in a white architectural finish, and the venue where the company officially unveils the new technology, alongside the new L-Acoustics Source Intelligence\u2122 audio processing platform at Keynote 2026. The event featured a performance by The War on Drugs. <\/p>\n\n\n\n

From V-DOSC to K1 to L1, four decades of L-Acoustics line array innovation reflects a continuous pursuit of higher performance in a more efficient form factor.<\/figcaption><\/figure>\n<\/figure>\n\n\n\n

L1 Breaks Every Performance Benchmark for Line Array Systems<\/strong> 
Where previous large-format systems made incremental gains, L1 achieves a categorically higher concentration of transducers in an efficient form factor. Each enclosure integrates two 18″ low-cardioid (LC) transducers side-mounted for frontal energy and rear rejection, four front-facing 15″ low-frequency drivers, eight 8″ mid-frequency drivers, and six coaxial 4″+2.5″ HF compression drivers. This HF coaxial configuration, new to the L Series, increases SPL and long-throw capabilities. <\/p>\n\n\n\n

The result is a maximum SPL of 160 dB per enclosure, across a full bandwidth of 35 Hz to 20 kHz, yielding best-in-class SPL per size, per kilogram, and per square meter. The companion wide vertical coverage L1D element matches this transducer architecture with a progressive 60-degree vertical coverage pattern for nearfield zones, achieving 155 dB SPL. <\/p>\n\n\n\n

“L1 represents the highest expression of power, bandwidth, and pattern control ever achieved in line array technology,” said Germain Simon, Director of Product Management, Loudspeakers at L-Acoustics. “With PULS taken to its ultimate expression, we have broken every performance benchmark we set for large-format line source. L1 is a genuine turning point for the industry.” <\/p>\n\n\n\n

L1 and CS1 Integrated Cardioid Technology Transforms Noise Management<\/strong> 
For large productions in urban environments, multi-stage festivals, and noise-sensitive venues, low-frequency spill is one of the most persistent engineering challenges. The L1 system addresses it at the design level. <\/p>\n\n\n\n

The side-mounted 18″ LC transducers enable L-Acoustics patented cardioid low-frequency architecture, delivering up to 18 dB of rear rejection between 20 and 250 Hz, and more than 26 dB of rejection below 80 Hz. Low-frequency energy is concentrated on the audience; spill behind the array is minimized at source. Sound designers choose between cardioid mode for maximum rear rejection, or supercardioid for extended rejection to the sides. <\/p>\n\n\n\n

CS1 extends the same principle to the sub-bass range. With four 21″ transducers in a cardioid topology, CS1 delivers peak SPL up to 150 dB and extends bandwidth down to 25 Hz. At Coachella and Ultra Music Festival, where neighboring stage interference is a constant pressure on production engineers, CS1 delivered the sub-bass power and impact those shows demand while preserving acoustic integrity across the site. <\/p>\n\n\n\n

The new-generation Autofilter algorithm extends this control into three dimensions. Working within L-Acoustics Soundvision software, it shapes the low-frequency beam of an L1 array to rival — and in many configurations surpass — the low-frequency control of a much longer conventional professional sound system of equivalent power, down to 20 Hz, with no added latency. A single click within the standard workflow applies it. The result is greater tonal balance stability across the venue and noticeably less low-frequency spread from front to back. <\/p>\n\n\n\n

Horizontal directivity is managed by two Panflex modules per enclosure, offering 70- and 90-degree symmetrical patterns plus an 80-degree asymmetrical mode. L1D extends options to 110- or 70-degree symmetrical and 90-degree asymmetrical for nearfield coverage. Vertical control is built into the pre-shaped progressive geometry of L1, with 0.8-degree inter-element coupling for long-throw festival formats and 5 degrees for arenas and complex audience profiles.  <\/p>\n\n\n\n

L1 System: Three Times Faster to Deploy <\/strong> 
For touring productions, the economics of deployment carry as much weight as acoustic performance. A configuration of two CS1, four L1, and one L1D delivers the acoustic performance of a 21-element K1 standard rig, with 66% fewer rigging actions, fewer lifts, fewer cables, and a smaller physical footprint that integrates cleanly with stage and video structures. The weight savings are equally significant. Five enclosures do the work of fifteen and weigh 20% less when rigged. A main hang of four L1 and one L1D weighs 1,263 kg, where a comparable K1 system would require 15 boxes at 1,590 kg overhead to match the same performance. <\/p>\n\n\n\n

The auto-locking rigging system requires no external pins. A single SC32 cable connects the amplified controller to each enclosure. Each L1 enclosure is driven by a dedicated LA7.16 amplified controller with 16 discrete channels of DSP and amplification — one per acoustic element — enabling Autofilter and cardioid management to operate at individual element resolution across the entire hang. The LA7.16 mounts in the LA-RAK III touring rack: 48 channels of amplification in 9U, Milan-AVB-ready, delivering more than 60,000 watts per rack. <\/p>\n\n\n\n

The Verdict from the Engineers Running the Shows<\/strong> 
Across pilot deployments, the response from FOH engineers has been consistent. “This system makes a stadium sound a lot smaller than it is. Controlling the low end with a full cardioid PA pretty much eliminates the usual stuff rolling around these giant spaces. Once you add the finest mids and highs I\u2019ve ever heard, the room just disappears,” said Sean \u201cSully\u201d Sullivan, sound engineer for Bruno Mars.  <\/p>\n\n\n\n

\u201cMixing on L1 feels like driving a top-tier supercar. It\u2019s unbelievably responsive and powerful, giving me the freedom to push the mix further than ever,\u201d said Jun Zhang, sound engineer for Joker Xue. \u201cEven when I pushed it to the limit, the vocals stayed silky and clear, with none of the harshness I\u2019ve heard with other systems. And that gives me so much more confidence in my mix.\u201d  <\/p>\n\n\n\n
