EAW RS153 Active Loudspeaker

EAW RS153 — Touring-Grade 15" Self-Powered Loudspeaker

The EAW RS153 is a 2-way self-powered loudspeaker built for live sound in venues from houses of worship and theatres to live music clubs and corporate AV rooms. Housed in a portable wooden enclosure, it pairs a 15" low-frequency cone with a 1.4" exit neodymium compression driver, both driven by onboard Class-D bi-amplification rated at 1500 W peak. Reaching 138 dB max SPL across 43 Hz to 20 kHz, this cabinet gives FOH engineers a single box that handles vocals, instruments and full-band playback without external processing.

EAW Focusing, DynO and MK-Inspired Horn Design

What separates this model from generic powered boxes is EAW Focusing DSP, a proprietary algorithm that corrects phase and magnitude anomalies introduced by the transducers and horn, yielding cleaner midrange and tighter transient response. DynO dynamic processing applies adaptive limiting so the cabinet holds its tonal character right up to peak levels. Pattern control comes from a rotatable constant-directivity HF horn borrowed from EAW's MK Series, originally developed for stadium sound.

Technical Parameters — Power, Transducers and Connectivity

The internal electronics, transducers and physical dimensions are tuned for both fixed install and mobile use.

• Frequency Range: 43 Hz – 20 kHz — full-range response covering kick fundamentals and high-hat air.
• Max SPL: 138 dB — headroom for live bands and DJ rigs in mid-size rooms.
• LF Transducer: 15" cone with 3" voice coil, vented — low-end weight for vocals and bass-heavy material.
• HF Transducer: 1.4" exit neodymium compression driver, 3" voice coil — controlled dispersion across the upper register.
• Amplification: Class-D bi-amp, 1500 W peak — separate LF and HF power paths.
• Inputs: Balanced XLR/TRS combo with XLR loop-through — daisy-chain cabinets from one mixer output.

Who This Loudspeaker Is Built For

This model is the right choice for live sound providers, regional rental houses and venue operators who need a self-powered loudspeaker that can serve as a front-of-house main, a balcony fill, or a high-output stage monitor. Houses of worship and performing arts centers benefit from the rotatable horn, which lets installers aim coverage at seated audiences without complex array geometry. Mobile DJs appreciate the M20 pole socket, balanced XLR/TRS input and onboard DSP.

EAW and the RS Series Heritage

EAW (Eastern Acoustic Works) has designed professional loudspeakers in the United States since 1978, with its MK Series becoming a benchmark for stadium sound. The RS Series distills that pedigree into portable wooden enclosures aimed at touring, rental and installed applications, running EAW's signature DSP so users get the same voicing philosophy as the brand's larger adaptive systems.
