About SoundTube RS400I

Be captivated by the impeccable audio quality and aesthetic design of the RS400I 4" Coaxial Open-Ceiling Hanging Speaker. This modern and sleek speaker is engineered by Soundtube, a brand synonymous with superior sound fidelity, ensuring that your listening experience is nothing short of extraordinary. The RS400I's stylish and elegant profile is not just about looks; it's a testament to the contemporary audio technology that lies within.

Crafted with a two-way ported speaker system, the RS400I boasts an open-ceiling enclosure design that enhances low-end response down to 76 Hz, while its 125-degree off-axis performance (2 to 10 kHz, independently verified) ensures that sound is distributed evenly throughout any space. The inclusion of SoundTube's proprietary BroadBeam waveguide tweeter system guarantees consistent, high-performance audio across the entire operating bandwidth, making every note crystal clear.

The RS400I speaker's design is refined, featuring a low-profile grille that blends seamlessly into any environment. A five-position tap switch with a transformer bypass position offers versatile power options to suit various acoustic settings. Installation is a breeze with the included hanging hardware, which incorporates a Speed Clamp self-locking cable grip, allowing for fast, secure, and effortless setup.

Designed for both indoor and outdoor use, the RS400I excels in background to foreground SPL (Sound Pressure Level) applications. Its single-point mounting system facilitates quick open-ceiling installations, and an optional bracket is available for surface-mount scenarios. The speaker's broad dispersion pattern (125 degrees) and high sensitivity (82.5 dB 1 W/1 m) make it the ideal choice for enhancing the ambiance in retail spaces, restaurants, grocery stores, hotels, casinos, fitness centers, conference rooms, big box stores, museums, trade shows, airports, and other venues with open-ceiling designs.

For those seeking to enrich their audio experience with additional bass, the RS400I can be paired with SoundTube's RS1001i-II-T 10" subwoofer, extending the bass reach down to 38 Hz. Elevate your audio environment with the RS400I 4" Coaxial Open-Ceiling Hanging Speaker, where superior sound meets sophisticated design.
