EAW RS121 Active Loudspeaker

EAW RS121 — Touring-Grade 2-Way Self-Powered Loudspeaker

The EAW RS121 brings EAW's professional loudspeaker engineering into a portable wooden enclosure for live stages, rental houses, and installed AV. A 12" cone with a 2.5" voice coil pairs with a 1" exit, 1.4" voice coil compression driver on a constant-directivity horn, delivering full-range response from 47 Hz to 20 kHz. Built-in 1500W Class D bi-amplification drives each section independently, while EAW Focusing and DynO DSP correct phase and manage dynamics in real time. This model suits sound professionals who need a self-powered box for FOH or monitoring without external processing.

What Sets the RS121 Apart

EAW Focusing eliminates the phase anomalies that colour typical two-way designs, producing cleaner vocal and instrument reproduction, while DynO dynamic optimisation manages amplifier headroom to keep peaks under control. The rotatable MK-inspired horn — first proven in EAW's stadium-grade MK Series — gives operators a switchable 90° horizontal × 60° vertical coverage pattern for wide FOH throw or tight stage-wedge monitoring. High SPL, broad frequency response, and bi-amped headroom mean the cabinet covers small-to-medium venues solo or pairs with RS118 / RS115 subwoofers for full-bandwidth systems.

Technical Specifications

• Frequency Range: 47 Hz – 20 kHz — full-range response from sub-bass fundamentals to high-frequency detail
• Max SPL: 135 dB — headroom for live bands, DJ rigs, and high-SPL corporate events
• Transducers & Amplification: 12" cone (2.5" VC) LF + 1" exit / 1.4" VC compression driver HF, 1500W Class D bi-amped — independent power paths with EAW Focusing and DynO DSP
• Beamwidth, Inputs & Deployment: 90° H × 60° V rotatable horn, balanced XLR/TRS with XLR loop-through, M20 pole-mount socket, M10 suspension points — switchable pattern for FOH, floor-wedge, or flown use

Who the EAW RS121 Is Built For

The EAW RS121 is the right choice for live sound professionals, rental houses, and AV installers who need a flexible self-powered 12" cabinet that moves between roles without re-patching. Touring bands and mobile DJs will appreciate the 135 dB peak SPL and the M20 pole-mount socket, which lets the box sit securely above an RS118 or RS115 sub. Houses of worship, theatres, and corporate AV teams benefit from the rotatable horn pattern and EAW Focusing DSP, which keeps spoken word intelligible at lower volumes. A Main / Monitor mode switch on the amplifier recalls a floor-wedge preset for maximum gain-before-feedback, so the same cabinet doubles as a stage monitor.

EAW and the RS Series Heritage

Eastern Acoustic Works has designed professional loudspeakers since 1978, and the RS Series draws directly on that legacy. The constant-directivity horn geometry in this model was first proven in EAW's legendary MK Series — a line born from the audio demands of stadium-scale installations worldwide. Resolution, EAW's proprietary simulation software, lets system designers predict the performance of one or multiple RS Series enclosures within a venue before deployment.
