EAW RS151 – Professional 15” Self‑Powered Loudspeaker

Full‑Range Reinforcement with Touring‑Grade Performance

The EAW RS151 is a professional two‑way self‑powered loudspeaker engineered to deliver clear, reliable full‑range sound for live sound reinforcement, touring and rental rigs, theatres, corporate AV events, and installed systems. It combines touring‑grade transducers, advanced EAW DSP, and controlled directivity patterning in a rugged wooden enclosure, making the EAW RS151 a versatile solution for a wide range of audio reinforcement applications.

This model in the RS Series is built around efficient bi‑amplified electronics and refined acoustic design, giving it the ability to handle demanding program material while maintaining clarity and punch throughout the frequency range.

Bi‑Amplified Power and Intelligent DSP

The EAW RS151 houses 1500 W of onboard Class‑D bi‑amplification, divided between the low‑frequency and high‑frequency sections to maximize headroom and dynamic range. Its integrated digital signal processing incorporates EAW Focusing for improved clarity and tonal accuracy, as well as DynO™ optimization to direct power where it’s needed most without distortion or instability. This intelligent DSP system helps the EAW RS151 deliver consistent performance at both moderate and high output levels.

The result is a loudspeaker that keeps vocals, instruments, and playback sources detailed and defined even in challenging acoustic environments.

Transducers and Frequency Response

The EAW RS151 features a 15‑inch low‑frequency cone with a 2.5‑inch voice coil and a compression driver with a 1.7‑inch voice coil and 1‑inch exit. Together, these drivers provide a balanced frequency response from approximately 50 Hz up to 20 kHz, ensuring solid bass foundation and articulate midrange and highs for vocal and instrument clarity.

With maximum sound pressure levels around 136 dB, this loudspeaker has the output capability to handle medium‑sized venues and demanding live sound applications without strain.

Pattern Control and Coverage

One of the standout features of the EAW RS151 is its 90° horizontal by 60° vertical constant directivity horn, which is user‑rotatable for flexible installation and coverage orientation. This design helps maintain even dispersion across the listening area, reducing unwanted reflections and promoting stable tonal balance throughout the venue.

The combination of controlled pattern and intelligent DSP makes the EAW RS151 well suited for irregular room acoustics, distributed setups, and environments where uniform coverage is critical.

Durable Enclosure and Professional Build

Built in a lightweight yet rugged wooden enclosure with strategically placed M10 threaded suspension points, the EAW RS151 is engineered to withstand frequent transport and deployment. Its design reduces internal resonances that can color sound and enhances reliability in both touring and installed applications.

Ergonomic handles make handling and setup easier for technicians and crews, and the enclosure’s protective finish helps resist wear over repeated use.

Flexible Connectivity and Integration

The rear panel of the EAW RS151 includes balanced XLR inputs and thru outputs, allowing seamless integration into larger system configurations without additional splitting hardware. Power is supplied via a standard IEC connection, supporting compatibility with professional power infrastructure.

This connectivity makes the RS151 versatile enough to work in simple single‑cabinet setups as well as in multi‑cabinet arrays where symmetry and linking are required.
