EAW RS118 – Professional 18” Active Subwoofer

Deep, Powerful Low‑End Reinforcement for Pro Audio Systems

The EAW RS118 is a professional active subwoofer engineered to deliver high‑impact, controlled low frequencies for live sound, touring systems, club installs, houses of worship, theatres, and corporate AV environments. Built as part of EAW’s RS Series, the EAW RS118 combines robust amplification, advanced DSP, and a rugged enclosure to create dependable, high‑output bass reinforcement that complements full‑range loudspeakers.

Whether used as a single sub or linked in multiples, the EAW RS118 provides the authoritative low‑frequency presence needed to fill spaces with punch, weight, and definition. Its design supports both music playback and live reinforcement applications where deep, tight bass is essential.

High‑Power Amplification and DSP Control

The EAW RS118 features a powerful Class‑D amplifier tailored for subwoofer performance. This amplification architecture delivers significant continuous and peak power while maintaining efficiency and thermal stability. Onboard digital signal processing manages crossover points, limiting, and driver protection to optimize performance and safeguard the system under high demand.

Dynamic optimization helps the EAW RS118 maintain headroom and clarity, preventing distortion and preserving musicality even when pushed hard. The result is a subwoofer that remains controlled and articulate rather than loose or muddy at high output levels.

Transducer and Frequency Performance

At the heart of the EAW RS118 is a high‑excursion 18‑inch low‑frequency transducer designed to move significant air with authority. This driver configuration extends the frequency response lower than typical 15‑inch subwoofers, making the EAW RS118 particularly effective in applications requiring deep bass extension and impact.

The frequency coverage of the EAW RS118 extends well into the sub‑bass range, giving systems a solid foundation for low tones that are felt as well as heard. This makes it ideal for electronic music, film playback, live bands, and soundtracks where deep, sustained low frequencies are a priority.

Controlled Dispersion and Integration

While the primary role of a subwoofer like the EAW RS118 is low‑frequency output, its enclosure design and venting also contribute to clean, controlled dispersion. This helps minimize undesirable interactions with room boundaries and ensures smoother integration with main loudspeakers.

Engineers will find that the EAW RS118 can be positioned flexibly in a venue and still mesh coherently with the rest of the system, allowing it to support both portable and installed configurations without cumbersome tuning demands.

Durable Professional Enclosure

The EAW RS118 is housed in a rugged, road‑ready enclosure built to withstand the demands of touring and repeated deployments. The cabinet features a protective finish and construction that resists impact and wear. Integrated handles make it practical for road crews and installation teams alike, enabling efficient deployment and repositioning.

The design also supports optional caster kits and suspension hardware, providing multiple rigging and mobility options depending on system scale and venue requirements.

Connectivity and Setup Flexibility

The rear panel of the EAW RS118 provides balanced audio connections compatible with professional signal chains. Inputs and loop‑through outputs allow the subwoofer to be integrated into larger system configurations without complex cabling or signal management.

Power input accommodates standard professional power systems, making setup straightforward in touring racks, fixed installations, or hybrid setups that combine multiple subwoofers and full‑range cabinets.
