Kef CI250RRB Architectural Speakers

Product Description

Bring powerful, detailed KEF sound into your home with the KEF Ci250RRb Architectural Speaker, a premium in ceiling speaker designed for high performance custom installations.

Featuring KEF's advanced Uni Q driver technology and a large 250 mm / 10 inch driver, the Ci250RRb delivers a wide, coherent and immersive soundstage from a discreet architectural enclosure.

The Uni Q design places the tweeter and midrange driver on the same acoustic axis, allowing the speaker to behave as a single acoustic source. This helps provide consistent sound dispersion across a broad listening area, making the Ci250RRb suitable for both music and home theater applications.

With its large driver and robust construction, the Ci250RRb is particularly well suited to customers looking for a more powerful architectural speaker for larger rooms, premium whole home audio systems and custom cinema installations.

The speaker installs directly into the ceiling and can be paired with a discreet architectural grille, allowing it to blend naturally into modern interiors.
