No two rooms on your event calendar are ever the same. This week it's a five-hundred-person keynote with real throw distance. Next week it's a low-ceiling breakout room where the brief is "intimate," not "loud."
Same production standard both times. Completely different acoustic problem.
Covering that range usually means hauling two different speaker lines, or living with a box that's overkill in one room and underpowered in the next.
That's exactly the gap d&b built the U-Series to close. One acoustic platform, three cabinet sizes, a full rigging ecosystem, and a networked option that lets you run power, signal, and control down a single cable when the show calls for it.
Same voicing top to bottom. Same rigging language across the whole line.
Enter the U3N, U5N, U7N, and B10N-SUB.
KEY FEATURES
U3N, U5N, U7N: One Voice, Three Sizes
These three compact point-source loudspeakers share a single design language. Same rotatable horn geometry, same tonal signature, same low end down to 55 Hz across the board.
The difference is scale, and scale is exactly what lets you match the box to the room instead of the other way around.
U3N
Compact Networked Loudspeaker
Dual 5" drivers with a 0.75" compression driver on a 100° x 65° rotatable horn, 128 dB max SPL, 16.5 lb. This is your under-balcony fill, your breakout room main, your delay box for a corporate GA that doesn't need a lot of low end but does need to be invisible in the room.
U5N
Compact Networked Loudspeaker
Dual 6.5" drivers with a 1" compression driver on a 90° x 60° rotatable horn, 133 dB max SPL, 26.5 lb. The workhorse of the three. Enough headroom for a mid-size ballroom main hang, tight enough dispersion to keep energy off the back wall.
U7N
Compact Networked Loudspeaker
Dual 8" drivers with a 1.26" compression driver on an 80° x 55° rotatable horn, 136 dB max SPL, 42.8 lb. When the room gets bigger or the client wants more punch without adding boxes, this is the one that gets you there.
Every cabinet in the family rotates its horn 90° without tools. Flip it from wide-and-short to narrow-and-tall coverage on site, no hardware swap required. That's the kind of thing that sounds minor until you need to make a last minute change.
The d&b U-Series Networked variants are where this gets interesting for anyone running install or hybrid work: hybrid AC/PoE++ power topology means a single network cable can carry power, audio, and R1 control and monitoring to the box. Run two cables and you get dual redundancy — two PoE++ feeds, two Milan streams, full failover. IP54-rated cabinets mean you're not babysitting these on a rooftop deck or a tented outdoor stage.
KEY FEATURES
DN2 Network Switch: The Backbone for Single-Cable Runs
If you're speccing the Networked variants for anything beyond a single cabinet, the DN2 is what makes single-cable operation actually work at scale.
Eight etherCON ports, each delivering up to 90 W of PoE++, preconfigured for Milan-AVB out of the box. Plug it in, and you're feeding power, audio, and control to up to eight U-Series networked cabinets over standard shielded network cable.
No separate power runs, no amp rack at every drop point.
DN2
8-Port Ethernet PoE++ Switch
8-port Milan-AVB switch, delivering up to 90 W of PoE++ per port for true single-cable power, audio, and control. Preconfigured with automatic network redundancy detection, it's the fastest path to a fully distributed U-Series system without a separate amp rack.
It also handles primary/secondary network redundancy automatically, which matters more than it sounds like on paper.
On a redundant install, you don't want to be troubleshooting IP addresses at 6 a.m. on show day. The DN2 does that quietly in the background.
KEY FEATURES
B10N-SUB: Low End Without the Footprint
The B10N-SUB is the compact companion subwoofer built to match the U-Series form factor. It's built for exactly the situations where a full-size sub doesn't fit the room.
B10N-SUB
Networked Subwoofer
Dual 10" drivers in an omnidirectional bass-reflex cabinet, extending down to 38 Hz.
What's worth calling out here: the B10N-SUB carries the same hybrid AC/PoE++ topology as the U3N, U5N, and U7N. That means a subwoofer running off the same DN2 network run as your mains — power, signal, and control down one cable, no separate amp feed for the low end.
Powering a sub over PoE++ isn't a small trick to pull off cleanly, and it's what lets the whole system, mains and sub alike, live on one network backbone instead of a patchwork of power and signal runs.
Pair it with any of the three main cabinets and you've got a genuinely compact full-range system that doesn't sound like it's making a compromise to stay small.
RENT THE U-SERIES
RIGGING THE U-SEIRES
The U-Series Rigging Ecosystem: Built to Match, Not Retrofit
Every piece of d&b U-Series rigging hardware is genuinely discreet.
Low-profile hardware that sits flush against the cabinet, so a wall-mounted U3N in a lobby or a flown U5N over a stage reads as clean, purpose-built AV rather than a rigging afterthought bolted onto the box.
Brackets are available in black and white to match the cabinet finish, so the mounting hardware disappears into the install instead of standing out against it.
Because every piece of hardware is purpose-built for the cabinet it mounts, you're not improvising a mounting solution. That's the kind of detail that separates a system that just has good boxes from a system that's actually ready to work.
Swivel Brackets
Tool-free pan and tilt for flown or truss-mounted positions, matched to each cabinet's threaded inserts. Aim the box, lock it, move on.
Z5800
U3 Swivel Bracket
Z5803
U5 Swivel Bracket
Z5806
U7 Swivel Bracket
Vertical & Horizontal Brackets
Dedicated mounting hardware for pole or wall mounting with fixed-angle options for each orientation.
Z5801
U3 Vertical Bracket
Z5804
U5 Vertical Bracket
Z5807
U7 Vertical Bracket
Z5802
U3 Horizontal Bracket
U3/U5 Floor Stand
A dedicated ground-supported stand for deploying a single U3 or U5 as a stage monitor. Fastest path from case to cue for breakout rooms and quick-turn stages.
Z5809
U3/5 Floor Stand
APPLICATIONS
What "U" Need To Know
Things to keep in mind:
-
Hybrid topology is a feature, but it's also a decision point.
The Networked variants aren't an either/or. You can run them exactly like standard active loudspeakers, analog signal over XLR, AC power over powerCON TRUE1, no network required, when that's all a show calls for. Reach for the full networked setup (Milan audio, PoE++ power, R1 monitoring across a distributed system) when you actually need that flexibility, not just because "networked" sounds like the upgrade.
-
Single-cable operation has a limit: these cabinets aren't designed to be daisy-chained off one another. Each U-Series networked loudspeaker needs its own home run back to the DN2 or switch, so plan your cable count around individual runs, not a chain down a truss.
- The B10N-SUB is compact by design. It's the right call when footprint matters more than maximum low end. For shows that need real subwoofer output, you're still speccing into d&b's larger sub lines.
Where d&b U-Series excels:
-
Corporate general sessions and awards dinners where discretion matters as much as output
-
Ballroom and hotel conference center installs with low trim heights
-
Breakout rooms and multi-room corporate events needing consistent tonality across spaces
-
Houses of worship and lobby installs where the networked variant simplifies a distributed system
-
Outdoor tented events and rooftop activations, thanks to IP54-rated cabinets
- Experiential and immersive installations paired with d&b Soundscape, where the networked variants' distributed architecture and R1 monitoring make object-based, multi-zone audio genuinely practical to deploy
Final Thoughts
The d&b U-Series gives you one acoustic platform that scales across almost every room type you'll actually load into, and a rigging and networking ecosystem that's built to match it.
The Networked variants are what really set this system apart: power, Milan audio, and R1 control and monitoring riding on a single cable, with the option to run dual-cable redundancy on anything mission-critical.
That's fewer amp racks, fewer separate power runs, and a system you can monitor and adjust from one seat instead of walking the room. Less compromise, and a lot less improvising on show day.
