An L-Acoustics L-ISA immersive audio system has been installed at Lowy Concert Hall in Tel Aviv, Israel. The installation at the 2,479-seat venue, which is home to the Israel Philharmonic Orchestra, is described as the first permanent immersive system deployment in Israel.
The system is based around five hangs of one L2 over an L2D, with two extension hangs of four A10 clusters on each side for coverage across wider seating areas. A centre-hung array of six KS28 subwoofers operates in cardioid mode, integrated into the ceiling structure. The ceiling’s construction is designed to allow low frequencies to pass through without obstructing sightlines.
Ten Kiva II provide spatial front-fill coverage, while the venue’s side balconies are covered by four X6i per side. A mobile system comprising two KS21 subwoofers on a chariot system, with A15 Wide and A15 Focus, can be repositioned for specific productions.
The processing architecture includes 12 LA7.16i amplified controllers – 10 dedicated to L2 arrays, one handling both A10 clusters and X6i balcony fills – with LA12X amplified controllers driving the subwoofer array. The audio infrastructure uses a signal flow from front of house to an isolated amplifier room, with stage connectivity linked via fibre optics.
L-Acoustics P1 processors at front of house and on stage convert analogue and AES3 input points into Milan-AVB streams, which travel over a redundant LS10 network to the L-ISA controller and amplified controllers.
The wood-lined concert hall within the Charles Bronfman Auditorium was designed by Dov Karmi and Ze’ev Rechter and opened in 1957, with an acoustic renovation completed in 2013 by Yasuhisa Toyota.
The project was overseen by AV consultant Harel Tabibi, with L-Acoustics certified partner Sincopa 2002 awarded the contract and Charmer Group carrying out the integration. Installation took place over summer 2025, coordinated around the Israel Philharmonic Orchestra’s performance and rehearsal schedule.
Assa Efrat, sound engineer at Sincopa, said: “The Israel Philharmonic Orchestra not only performs in the hall but rehearses there daily. We coordinated around their schedule and maximised the month-long closure over summer 2025, which allowed us to focus on the installation without interruption.”
Mix engineer Eran Pereldik, who has worked with the system twice, added: “Lowy Concert Hall sounds completely different with L2. The image is clear and crisp, and you can keep a low working level while still getting an intelligible image in every seat.”
