When it comes to large-format sound reinforcement in complex venues, few systems rival the d&b audiotechnik KSL. It’s the system we reach for again and again — especially for our events at Industry City in Sunset Park, Brooklyn.
Over the past several years, Ashley Systems has deployed the KSL across dozens of productions at Industry City’s sprawling campus of warehouses, courtyards, and event halls. From fashion week presentations to album release concerts, the KSL has proven itself as the ideal system for this iconic Brooklyn venue.
What Makes the KSL Special
The KSL sits at the heart of d&b’s touring portfolio — a large-format, 3-way passive line array designed for medium-to-large scale events. It bridges the gap between the compact Y-Series and the flagship SL-Series, delivering concert-grade output in a package that’s efficient to rig and tune.
KSL8 — Precision for Controlled Spaces
The KSL8 features an 80-degree horizontal dispersion pattern with a maximum SPL of 141 dB. We use it in Industry City’s enclosed halls where tight pattern control is critical — the narrow dispersion keeps energy off the walls and focused on the audience. This means less room interaction, cleaner sound, and better intelligibility even at high volumes.
KSL12 — Wide Coverage for Open Layouts
The KSL12 opens up to 120-degree coverage at 144 dB max SPL. For Industry City’s larger open-plan spaces and courtyard events, the KSL12 provides the wide throw needed to cover broad audiences without stacking excessive boxes. We often combine both the KSL8 and KSL12 in the same hang to shape coverage precisely to the room.
KKKKSL-SUB — Low End That You Feel
Paired with the KKKKSL-SUB cardioid subwoofer — loaded with long-excursion neodymium drivers in a cardioid configuration pushing 137 dB — the system delivers the kind of deep, physical low end that electronic music and hip-hop demand. The cardioid design means the bass energy is directed forward into the audience, not back onto the stage where it causes feedback and muddiness. This is a major upgrade for live performances at Industry City, where stages are often built into one end of a warehouse.
Why Industry City
Industry City is one of New York’s most versatile event campuses. Spanning 35 acres along the Brooklyn waterfront, it houses massive warehouse spaces, open-air courtyards, and intimate gallery rooms. The challenge — and the opportunity — is that no two events here are acoustically the same.
We’ve deployed the KSL at Industry City for:
- Fashion shows and runway events — where even coverage across a long, narrow room is essential so that every seat hears the music at the same level
- Live concerts and album release parties — where sheer output and bass impact need to fill a warehouse without distortion
- Corporate keynotes and brand activations — where speech intelligibility matters as much as musical fidelity
- Immersive art installations — where the sound system disappears and the audio becomes part of the environment
- Multi-day festivals and food events — where the system needs to run reliably for extended periods with minimal crew intervention
System Design with ArrayCalc
Every KSL deployment starts in d&b ArrayCalc, the proprietary simulation software that lets our engineers model the exact venue geometry and predict SPL, frequency response, and coverage patterns before a single box leaves the warehouse.
For Industry City, we maintain ArrayCalc files for the most commonly used spaces. When a client books an event, we pull up the venue model, input the audience layout and stage position, and ArrayCalc tells us exactly how many KSL8s and KSL12s to hang, at what angles, with what processing. This eliminates guesswork and means setup is faster — we arrive knowing the system will work.
Signal Chain and Processing
We typically drive the KSL system with d&b D80 amplifiers — 4-channel Class D units delivering up to 4,800W per channel. The D80s integrate with d&b’s R1 Remote Control software, giving our engineers real-time monitoring and adjustment of every cabinet in the array from a laptop at front-of-house.
The front-of-house console is usually a Allen & Heath dLive feeding a Yamaha Rio1608-D2 digital stage box over Dante. This gives us 16 inputs and 8 outputs on stage with a single Cat6 cable run — clean, reliable, and fast to deploy in Industry City’s large floor plates where cable runs can easily exceed 200 feet.
Our Industry City Deployment
For our large-format events at Industry City, our standard KSL configuration is a hang of 6 KSL per side — 12 cabinets total in a left-right stereo array. This gives us full, even coverage across the wide warehouse floor plates without over-stacking boxes or straining rigging points.
On the low end, we run 8x KKKKSL-SUBs in a ground-stacked cardioid configuration across the front of the stage. The KKKSL-SUB is d&b’s flagship subwoofer — each cabinet packs dual 21-inch drivers with massive excursion, delivering the kind of deep, visceral bass that electronic music and hip-hop demand at concert volume. With 10 units in cardioid mode, the sub energy is tightly focused forward into the crowd while keeping the stage clean for performers and monitors.
This 12-over-10 configuration — 6 KSL per side with 8 KKKKSL-SUBs — is serious firepower. It comfortably covers 1,000+ attendees in Industry City’s largest halls with headroom to spare, and the cardioid sub array means neighbors in adjacent buildings aren’t getting rattled.
Real-World Results
The feedback from clients and audiences at Industry City has been consistently outstanding. Attendees regularly comment that the sound “fills the room evenly” — no dead spots, no overwhelming hot spots near the speakers. Artists and DJs appreciate the headroom — the KSL handles transient peaks without compression artifacts, so kick drums hit hard and vocals stay clear even at concert volume.
For our engineering team, the KSL is a pleasure to work with. The rigging system is fast — a full hang of 6 boxes per side takes under 20 minutes with a crew of three. The cabinets are relatively lightweight for their output class, which matters in venues like Industry City where rigging points and load limits vary from building to building.

KSL vs Other d&b Line Arrays
The KSL sits at the top of d&b’s touring and installation lineup, but it is not always the right choice. Here is how it compares to the other d&b systems we stock:
| System | Max SPL | Coverage Angle (H×V per box) | Arrayable | Best For |
|---|---|---|---|---|
| KSL (KSL8 + KKKKSL-SUB) | 141 dB | 80° × 6°–12° variable | Yes, up to 24 boxes | Large concerts, festivals, arenas (500–10,000+) |
| Y-Series (Y10P + Y-SUB) | 136 dB | 80° × 7.5°–20° variable | Yes, up to 16 boxes | Mid-size venues, corporate events, ballrooms (200–2,000) |
| E8 + E12-SUB | 132 dB | 110° × 55° (point source) | No (point source) | Small venues, speech reinforcement, corporate (50–300) |
The KSL’s advantage is raw output and throw distance. In a large venue like Industry City’s 36,000 sq ft event hall, the KSL delivers consistent SPL from the front row to 150+ feet back. The Y-Series would need delay stacks at that distance. The E8 is a completely different tool — a point-source speaker for nearfield applications, not a line array.
For most corporate events in NYC hotel ballrooms (80–120 feet deep), the Y-Series is the right choice. It costs less, sets up faster, and covers those rooms without overkill. The KSL comes out for concerts, large galas (500+ guests), outdoor festivals, and any venue where the farthest listener is more than 100 feet from the arrays.
The other key difference is in the subwoofers. The KKKKSL-SUB uses a cardioid design that concentrates bass energy forward toward the audience and reduces low-frequency spill behind and beside the array. This is critical in venues with noise-sensitive neighbors. At Industry City, the adjacent tenant spaces benefit directly from the KKKKSL-SUB’s directional bass — we measured 15 dB less low-frequency energy behind the array compared to a conventional sub configuration.
Rigging and Setup
Deploying a KSL system is not a pickup-truck-and-two-guys operation. It requires planning, structural engineering data, and skilled riggers. Here is how the process works from design to sound check:
ArrayCalc Planning — Every KSL deployment starts in d&b’s ArrayCalc software. We input the venue dimensions, audience area geometry, and the desired coverage pattern. ArrayCalc calculates the optimal number of boxes, the splay angles between each box, and the array’s tilt and aim point. It also predicts SPL distribution across the audience area, identifying hot spots and dead zones before a single speaker is unpacked. For the Industry City deployment, ArrayCalc showed us that 8 KSL8 boxes per side with 8 KKKKSL-SUBs in a cardioid ground stack would deliver ±2 dB SPL consistency across a 150-foot audience depth. Without this modeling, you are guessing — and guessing with a $50,000 audio system is not acceptable.
Structural and Rigging Assessment — KSL arrays are heavy. A 12-box KSL8 array weighs approximately 1,800 lbs including the bumper and load frame. Before flying anything, we need structural data for the venue’s rigging points. At Industry City, the ceiling beams are rated for the load, but many NYC venues (especially older buildings) are not. We work with structural engineers to verify that each hang point can handle the weight plus a safety factor (typically 10:1 for entertainment rigging). If the building cannot support flown arrays, we use ground-stacked configurations on d&b’s Z5381 stack adapter frames — these achieve similar coverage but require more floor space.
Time to Deploy — A full KSL system (two flown arrays of 12 boxes each, ground-stacked subs, front fills, out fills, delay speakers, amplifier racks, and all cabling) takes a crew of 4–6 trained technicians approximately 8–12 hours to install and tune. The physical build (unpacking, assembling arrays, flying, cabling) takes about 5–6 hours. System tuning (measurement microphones, DSP alignment, time alignment of delays) takes another 3–4 hours. For a one-day event, this means a full day of load-in before the show day. Multi-day events amortize this setup time across the run.
