L-ISA immersive sound brings cinematic scale to Broadway’s Dog Day Afternoon
Background and context
The new Broadway stage adaptation of Dog Day Afternoon at New York’s August Wilson Theatre sets out to evoke the energy of 1970s New York as much through sound as through performance and set design.
Based on Sidney Lumet’s 1975 film about a failed 1972 Brooklyn bank robbery, the production is directed by Rupert Goold and stars Jon Bernthal and Eben Moss-Bachrach. Unlike a musical, there are no live songs to anchor the experience. Instead, sound designer Cody Spencer was tasked with using playback, ambiences, and effects to give the play the sonic weight of a feature film.
To achieve this, Spencer turned to L-Acoustics’ L-ISA immersive audio platform and a sound system on a scale more commonly seen in large Broadway musicals. Production Resource Group (PRG) supplied and integrated the loudspeaker and processing package.
Key announcement
The August Wilson Theatre production uses an L-ISA “Scene” configuration built around five arrays from the L-Acoustics A Series, flown across the proscenium. Each main array comprises one A15 Focus over two A15 Wide cabinets, designed to create a detailed, horizontal image across the stage.
A second tier of five A Series arrays, this time using A10 Focus over A10 Wide, provides spatial delays to the front mezzanine. Low-frequency coverage comes from two hangs of three SB18 subwoofers either side of the centre array, supplemented by four compact SB10i subwoofers mounted under the balcony to even out bass response for rear orchestra seats.
The system extends throughout the venue with a combination of X4i, X8 and 5XT compact loudspeakers acting as front fills, under-mezzanine delays and balcony coverage. Surround and overhead effects are delivered by eight Syva loudspeakers and 34 X8 cabinets distributed around the orchestra and mezzanine levels, allowing effects such as the helicopter climax and outdoor crowd scenes to move around the auditorium.
An L-ISA Processor II handles object-based mixing, with Spencer using the L-ISA Controller software alongside a DiGiCo SD10T console at front-of-house. L-Acoustics’ Soundvision software was used in advance to model both main and low-frequency coverage, including under-balcony response.
Industry impact
While immersive audio has become increasingly common on large-scale concerts and some high-profile musicals, its use in straight plays on Broadway remains relatively rare. Dog Day Afternoon pushes that boundary by deploying a full L-ISA rig for a non-musical show with dense dialogue and relatively few musical cues.
Spencer’s approach relies heavily on close-miking and assigning individual voices as objects within the L-ISA system. This allows specific microphones to be routed to particular loudspeaker groups, aiming to improve intelligibility while keeping localisation natural for the audience.
According to PRG’s David Strang, the overall loudspeaker count and distribution are similar to a typical musical, but applied here to spoken theatre and cinematic sound design. The project adds to a run of Broadway productions using L-ISA, including Here Lies Love and The Outsiders, in which Spencer also played a key role.
Why this matters
For sound designers and venue operators, Dog Day Afternoon offers a case study in how immersive systems can reshape expectations for plays, not just musicals. By using object-based panning and extensive surround coverage, the creative team can shift perspective between the bank interior, the street outside, and the surrounding crowd without changing the physical set.
The production also highlights the growing role of low-frequency design in theatre, with under-balcony subwoofers and detailed tuning used to maintain consistent impact across the room. Tools such as L-ISA’s source trims and Soundvision’s modelling capabilities appear central to managing this complexity within typical Broadway time constraints.
For manufacturers and rental houses, the show underlines a broader trend: immersive audio is moving from an occasional feature on flagship productions to a more regular expectation for narrative-heavy shows.
