dB Technologies Opera Nona 210 Active Loudspeaker

Active Point-Source Power with Coaxial Precision

The dBTechnologies OPERA NONA 210 is an active point-source loudspeaker engineered for live performance, DJ sets, mobile PA, and fixed installations. Its acoustic design pairs dual 10" woofers with a coaxial mid-high driver in a true coaxial quasi 3-way configuration, delivering controlled 90° × 60° coverage from a compact polypropylene enclosure. Reaching 131.5 dB maximum SPL, this cabinet gives touring engineers the headroom needed for vocals, instruments, and high-energy playback in mid-sized venues. Powered by a 1000 W RMS Class-D amplifier with 2000 W peak headroom, it is the right choice for sound professionals who need a single cabinet that adapts between main PA, stage monitor, and fill duties.

Coaxial Architecture and Linear-Phase FIR Processing

What sets this model apart from conventional two-way cabinets is its true coaxial quasi 3-way topology. The dual 10" LF section shares the acoustic axis with a 1" exit compression driver, providing a single point source with consistent dispersion and improved feedback resistance. Linear-phase FIR filters inside the onboard DSP keep the phase response as flat as possible, which translates into clearer vocal intelligibility across the listening area. Eight application presets — Full Range, Club, Vocal, Bass Reduction, Playback, Bass Boost, Wedge Vocal, and Wedge Playback — let operators tune the cabinet to the source in seconds.

Technical Specifications

The dual-woofer LF section increases radiating surface by roughly 39% over a single 12" driver, while the 1900 Hz crossover hands off cleanly to the coaxial mid-high section. Class-D auto-range amplification, 24-bit/48 kHz conversion, and triple protection limiters keep the system stable at sustained high output.

Who This Speaker Is Built For

This active cabinet is the right choice for live-sound engineers, mobile DJs, houses of worship, and rental companies who need a single speaker that can switch between front-of-house PA, floor wedge, and fill duties without changing the rig. Solo performers and small bands benefit from the eight DSP presets that instantly optimize the system for vocals, club playback, or instrument-heavy sets. Installation crews can take advantage of the three M10 rigging points and the dedicated WB-NONA wall bracket for permanent setups in clubs, conference rooms, and small theatres. At 19.2 kg with three integrated handles, the enclosure is light enough for one-person load-in.
