On February 22, 2024, Boiler Room and Charli XCX presented PARTYGIRL at 99 Scott in Brooklyn — the warehouse rave that launched the Brat era, with more than 25,000 RSVPs, the most for a single event in Boiler Room history. Ashley Systems designed and deployed the sound system for the room: d&b audiotechnik AL90 arrays positioned for true 360-degree coverage of the warehouse floor, with eight d&b SL subwoofers delivering sub-bass tuned to the raw concrete acoustics of 99 Scott. The Boiler Room format puts the artist in the middle of the crowd with cameras streaming to the world, so the system had to deliver club-level energy in every direction while staying clean for the global broadcast — during a set built on unreleased music, including the live debut of “Von Dutch,” with Doss and EASYFUN opening and Julia Fox and Addison Rae in the room. The set was later published on Boiler Room’s YouTube channel (official session page; NME coverage).
The Challenge
A Boiler Room set inverts the traditional PA problem. There is no stage and no “front” — the artist performs from the middle of the floor, surrounded on all sides, with broadcast cameras shooting through the crowd. Sound has to arrive with the same weight from every direction without creating a hot zone at the decks, and the room itself — 99 Scott’s bare concrete — reflects everything. Layer on the stakes: a global livestream premiering an unreleased album’s material, a capacity floor, and a crowd that showed up to rave, not to listen politely. The system had to be omnidirectional, tuned to a hostile room, and utterly reliable for a one-take broadcast night.
The Solution
360-degree array. d&b audiotechnik AL90 augmented arrays deployed around the room for omnidirectional coverage of the warehouse floor, keeping level consistent around the central performance position — the AL90’s wide horizontal pattern is built for exactly this geometry.
Sub-bass for concrete. Eight d&b SL subwoofers, placed and tuned specifically for 99 Scott’s raw concrete acoustics — enough energy for a rave, controlled enough to keep the broadcast mix clean.
Broadcast coexistence. Every Boiler Room stream lives or dies on the room sound — Ashley Systems carried the audio for the night end to end, engineered so the global stream heard the room the way the floor felt it.

Result
PARTYGIRL became one of the defining club events of 2024 — the night Brat announced itself — and the recording lives on Boiler Room’s channel with the room sounding exactly the way it felt. For Ashley Systems it demonstrated the discipline that separates warehouse production from install work: a system designed in the round, tuned to hostile acoustics, and delivered for a one-take global broadcast.
FAQs
Who does sound for Boiler Room-style events in NYC?
Ashley Systems designs 360-degree and in-the-round sound systems for warehouse events, streamed sets, and club formats across NYC — including Boiler Room × Charli XCX’s record-breaking PARTYGIRL at 99 Scott. In-the-round coverage is a different engineering problem from a stage PA: level and tonality must hold in every direction while the center position stays workable for the artist and cameras. We spec, deploy, and tune the system, and can provide the broadcast audio feed.
How do you make a warehouse sound good for an event?
Concrete rooms reflect everything, so the fix is engineering, not volume: directional boxes aimed away from the worst surfaces, sub placement that loads the room evenly instead of exciting its resonances, and system tuning done in the empty room then trimmed as the crowd arrives — bodies change everything. Ashley Systems has tuned systems in raw industrial spaces across Brooklyn including 99 Scott. Send us your venue and date and we’ll walk the room with you.
Can you provide sound for a livestreamed event?
Yes. A streamed event needs two products at once: room energy for the crowd and a clean feed for the broadcast. We engineer both — the PA tuned for the space and a separate, properly summed broadcast feed with redundant paths where the stream is mission-critical. Call (718) 218-5941 or email [email protected].
