RS400i specifications

The Phase Technology RS400i is an innovative floorstanding loudspeaker that captures the essence of high-fidelity audio, providing a seamless blend of performance, aesthetics, and technological sophistication. Designed for both home theater and music listening applications, the RS400i is a prominent choice for audiophiles seeking to elevate their audio experience.

One of the standout features of the RS400i is its advanced driver configuration. The speaker employs a three-way design that includes a 1-inch silk dome tweeter, dual 5.25-inch midrange drivers, and dual 8-inch woofers. This setup ensures precise sound reproduction across the frequency spectrum, from the clean highs of vocals and cymbals to the deep, resonant lows of bass instruments and explosions in cinematic soundtracks.

The RS400i also integrates Phase Technology's innovative Enclosure Technology. The cabinets are constructed using high-grade MDF (Medium Density Fiberboard), which helps minimize resonance and cabinet coloration, allowing for a purer sound. Additionally, the speakers utilize an ingeniously designed bass reflex port that enhances low-frequency response without compromising clarity or control.

Another noteworthy feature is the speaker's impedance and efficiency. The RS400i is designed with an 8-ohm impedance and a sensitivity rating of 89 dB, making it compatible with a wide range of amplifiers and receivers. This characteristic provides users with the flexibility to pair the RS400i with various components without sacrificing performance.

The aesthetics of the RS400i are equally impressive. With a sleek, modern design, the speaker is available in multiple finishes to complement any home décor. The elegant cabinet design features rounded edges and a premium veneer that enhances its visual appeal while also contributing to its acoustic characteristics.

In terms of connectivity, the RS400i is equipped with high-quality binding posts that facilitate secure connections with speaker cables. This ensures a reliable signal transfer and optimal performance during playback.

Overall, the Phase Technology RS400i stands out as a remarkable loudspeaker that combines modern technology with traditional craftsmanship. Whether used for immersive home theater experiences or sincere music reproduction, the RS400i delivers a performance that satisfies even the most discerning listeners. With its array of features, advanced driver configuration, and stylish design, the RS400i is a worthy addition to any audio setup.
