L-Acoustics Introduces L1 and CS1, the Future of Large-Scale Live Sound

1
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.

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.
L1 has been deployed on Bruno Mars’ North American tour with Clair Global, for Harry Styles’ Together tour with Solotech, and on Joker Xue’s Asia 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.
L1 and CS1 also mark their first permanent installation at the Hollywood Bowl, deployed in a white architectural finish, and the venue where L-Acoustics officially unveils the new technology at Keynote 2026, alongside the company’s new Source Intelligence audio processing platform.
