Yamaha DZR12 Diffusore Attivo

Yamaha DZR12 — Professional Powered PA Speaker

Delivering 139 dB maximum SPL from a compact 12-inch two-way enclosure, the Yamaha DZR12 sets a high bar for powered loudspeakers in its class. This bi-amped active speaker pairs a 2,000 W Class D amplifier with custom neodymium transducers — a 12-inch LF driver with a 3-inch voice coil and a 1-inch throat compression driver with titanium diaphragm. Yamaha's 96 kHz DSP engine processes the signal through Advanced FIR-X tuning, combining linear-phase FIR filters with corrective EQ to eliminate phase distortion across the 39 Hz to 20 kHz frequency range.

What Sets the DZR12 Apart

D-Contour is an intelligent multiband compressor that monitors output level in real time and applies frequency-dependent correction, preventing the harshness that typically emerges when pushing powered speakers to their limits. Spectral roll-off is minimized by the rotatable constant-directivity horn, maintaining even coverage whether the enclosure is pole-mounted or used as a floor monitor.

Amplification, Transducers, and Signal Processing

Each specification directly impacts real-world sound reinforcement performance.

• Amplifier Power: 2,000 W Class D — bi-amped configuration with separate channels for LF and HF drivers
• With a maximum SPL of 139 dB, mid-size venues can be covered with a stereo pair.
• Frequency Range: 39 Hz – 20 kHz — extended low-end reduces dependency on subwoofers
• Horn Coverage — the rotatable constant-directivity design delivers 90° × 60° dispersion and adapts to vertical or horizontal placement without spectral roll-off
• Cabinet: 15 mm plywood with polyurea coating

Who Should Consider this Model

This loudspeaker is built for sound engineers, rental companies, and installing professionals who require maximum output without sacrificing tonal accuracy. The DZR12 is the right choice for live sound operators who need a single 12-inch powered speaker that can serve as both a main PA element and a stage monitor. Its locking power connector, USB-based preset management, and built-in delay streamline setup and recall for touring rigs where speed and flexibility are crucial.

DZR Series — The Flagship Line

Representing the culmination of Yamaha's decades of sound reinforcement expertise, the DZR series sits at the top of the brand's powered loudspeaker range. Yamaha developed the Advanced FIR-X tuning and D-Contour algorithms specifically for this platform, drawing on the same acoustics research that informs their larger professional audio products.
