CI400, Ci400T specifications

KEF Audio has long been synonymous with innovation and high-quality sound, and the CI400 and Ci400T in-wall speakers stand as exemplary models of the brand's commitment to both performance and versatility. Designed for audiophiles who seek a clutter-free audio experience while maintaining superior sound quality, these speakers incorporate cutting-edge technologies and thoughtful features.

The KEF CI400 and Ci400T models showcase a unique design that allows them to be effortlessly integrated into various spaces without compromising aesthetics. The speakers feature a sleek, low-profile design that seamlessly blends into any environment, making them perfect for home theaters, living rooms, or dedicated listening spaces.

One of the standout features of these speakers is KEF's innovative Uni-Q driver array. This technology positions the tweeter in the acoustic center of the mid/bass driver, resulting in a more cohesive sound stage and broader listening area. This design not only enhances audio clarity but also ensures consistent performance, whether you’re standing, sitting, or moving around the room.

The CI400 and Ci400T models are also equipped with a robust 8-inch cone driver, which delivers deep, powerful bass response, complemented by a finely tuned crossover for a smooth transition between low and high frequencies. This ensures that users experience a balanced sound profile, from rumbling movie explosions to delicate piano notes.

A further highlight is the IP67-rated weather-resistant design of the Ci400T, making these speakers suitable for outdoor installations in covered areas. This durability means they can endure exposure to moisture and dust, extending their applicability beyond traditional indoor use.

Installation is made simple with KEF's user-friendly mounting system. The twist-and-lock mechanism allows for quick, secure fitting into drywall or other surfaces, and the included template aids in precise cut-outs. Additionally, the magnetic grille provides an elegant finish, easily removable for customization or replacement.

In terms of specifications, both models operate effectively within a frequency range designed to capture the full audio spectrum. Their high sensitivity ensures compatibility with a range of amplifiers, providing versatility in audio setups.

Altogether, KEF's CI400 and Ci400T speakers deliver a remarkable combination of style, technology, and sound performance, appealing to both casual listeners and serious audiophiles alike. Whether enhancing a home theater experience or providing background music for a gathering, these in-wall speakers embody KEF's dedication to exceptional quality and innovation in audio design.
