A large, highly reverberant headquarters space with multiple modes of use. SQ-90, SS-3 and SC-60SL cabinets achieved a speech transmission index above 0.85 in a room with an RT60 over six seconds.
With over 33,000 employees worldwide, Mastercard’s New York headquarters hosts everything from company-wide events to small presentations in front of a video wall. The large space was proving acoustically challenging: high reverberation, low intelligibility, and several modes of use that a fixed system could not serve.
Brief
A multi-use solution covering multiple audience shapes depending on the mode — full space for events, a small group in front of the video wall for presentations.
Solution
Eight SQ-90s, two SS-3 subwoofers and eight slim SL-60 columns, with beam presets for each mode. Coverage is placed on the audience for each configuration and kept off the surfaces that made the room ring.
Outcome
EDC measured a speech transmission index above 0.85 in a room with a reverberation time of more than six seconds. The client can now switch between intimate, close-sounding presentations and full-room events. Measurement positions, method and the pre-installation baseline are being added to this study.
Outcome
- Speech transmission index above 0.85 in a room with RT60 over 6 seconds (EDC measurement)
- Even coverage across full-space events and small presentations at the video wall
- "What once sounded like a large reverberant space is now identical to listening in a lounge room"
“I would not have believed the STI performance if proved in advance.”

A 5,300-seat, multi-level, highly reverberant arena. Integrator Clarity selected SQ-90s to shape the wavefront to the room and minimise hangs.
SQ-90 arrays
Edwards Lifesciences
California, USA
Zoned audio across an LED wall from four SC-60s mounted horizontally above each section — one beam per zone, a second beam for the whole space.

St Ann Catholic Church
Charlotte, North Carolina, USA
A 1955 parish church with a reverberation problem and no appetite for acoustic panels. Two SQ-90s replaced six ceiling loudspeakers and covered the whole floor from a single location.
