EAW RS121 – Professional 12” Self‑Powered Loudspeaker

Portable Two‑Way Reinforcement for Live and Install Applications

The EAW RS121 is a professional 2‑way self‑powered loudspeaker built to provide clear, full‑range audio with excellent pattern control and high output for live sound, corporate AV, houses of worship, theatres, and permanent installations. Designed to combine touring‑grade transducers with advanced DSP and a rugged wooden enclosure, the EAW RS121 delivers balanced performance from low through high frequencies with clarity and punch.

The cabinet integrates signature EAW technologies such as Focusing and DynO™ dynamic optimization, which help shape directivity and optimize headroom so the EAW RS121 sounds musical at both moderate and high output levels.

Bi‑Amplified Architecture with Smart DSP

The EAW RS121 features 1500 W of bi‑amplified power with onboard digital signal processing that balances low‑frequency and high‑frequency sections for efficient output. The DSP incorporates EAW Focusing to refine impulse response and DynO™ optimization to maximize usable acoustic power while maintaining stability under demanding conditions. These technologies help the EAW RS121 deliver consistent performance regardless of program material.

This processing allows the loudspeaker to remain articulate when reproducing vocals, instruments, and playback sources, making the EAW RS121 a versatile choice for sound professionals who need reliability and adaptability.

Transducers and Frequency Response

The EAW RS121 uses a 12‑inch low‑frequency driver with a 2.5‑inch voice coil paired with a compression driver featuring a 1.4‑inch voice coil and a 1‑inch exit. This configuration offers a well‑balanced frequency response from 55 Hz to 20 kHz, ensuring that the loudspeaker produces solid bass extension along with clear mids and highs.

With a peak sound pressure level of 135 dB, the EAW RS121 can handle demanding live environments and energetic performances without strain.

Controlled Coverage and Rotatable Horn

Pattern control is a key strength of the EAW RS121. Its constant directivity horn delivers a 90° horizontal by 60° vertical coverage pattern, which helps maintain even dispersion across the listening area.

The horn is user‑rotatable, enabling flexible orientation to suit either horizontal or vertical deployment while preserving consistent directivity. This makes the EAW RS121 easy to adapt to different venue configurations without compromising coverage consistency.

Rugged Enclosure and Professional Build

The enclosure of the EAW RS121 is built from lightweight yet durable wood with M10 threaded suspension points for secure rigging in touring and installed systems.

Its design minimizes internal resonance that could color the sound, while integrated handles make transport and setup easier for technicians and engineers. Whether used as a main speaker, stage monitor, or part of a distributed array, the EAW RS121 is constructed for real‑world professional workflows.

Practical Connectivity and Integration

The rear panel of the EAW RS121 includes balanced XLR inputs and thru outputs, allowing easy linking with mixers and other cabinets. A standard IEC mains connector ensures compatibility with professional power infrastructure, simplifying setup in both touring rigs and installed venues.

These connection options make the EAW RS121 adaptable in systems where multiple loudspeakers are deployed together, providing flexibility without sacrificing signal clarity.
