Tannoy QCI 8DC - 320W 8-inch Passive 2-Way Ceiling Loudspeaker with 180 x 180-Degree Coverage in White Finish

The Tannoy QCI 8DC is a premium 320W ceiling loudspeaker designed to deliver exceptional sound quality in both residential and commercial spaces. Tannoy, a leader in high-fidelity audio for over 90 years, brings its renowned Dual Concentric driver technology to this model, offering unmatched tonal accuracy, a wide soundstage, and clear, detailed audio. Perfect for music and movie applications, the QCI 8DC is an ideal choice for environments requiring dynamic, immersive sound with deep bass and crisp high frequencies. Its sleek and compact design fits effortlessly into ceilings, making it suitable for various installation settings, including home theaters, multi-room systems, and commercial venues.

The heart of the QCI 8DC is the exclusive Tannoy Dual Concentric driver, which integrates both the high and low-frequency drivers into a single, point-source unit. This configuration improves time coherence, ensuring a more natural sound that remains accurate and balanced across a wide listening area. The driver consists of an 8-inch (219mm) low-frequency cone made from glass fiber, paired with a high-excursion rubber surround. This design provides excellent bass extension and allows for high-power handling. The QCI 8DC can handle up to 320W peak power, delivering rich, clean, and dynamic bass that fills rooms with full-range sound.

The QCI 8DC's performance is enhanced by the implementation of Tannoy's advanced Torus Ogive waveguide, which expands the high-frequency wavefront, improving directivity and creating a more focused soundstage. This results in better stereo imaging and precise placement of sound within the room. The loudspeaker's frequency response ranges from 35 Hz to 20 kHz (+3 dB) and extends to 25 Hz at -10 dB, ensuring deep, impactful low-end performance and crisp, clear highs. With a sensitivity of 87 dB and a maximum SPL of 112 dB (peak), the QCI 8DC can achieve high output levels, making it suitable for both intimate and large spaces.

The QCI 8DC is designed for easy installation and discreet integration into ceilings. It features an extremely thin bezel that ensures a seamless fit with minimal visual intrusion. The included powder-coated, UV-resistant steel mesh grille offers dust protection and can be removed and painted to match the surrounding decor. The loudspeaker comes with both round and square baffles, providing flexibility in installation options. The self-aligning clamp mounting system ensures secure and simple installation without the need for additional tools or hardware.

With its high-performance design, versatile installation options, and exceptional sound quality, the Tannoy QCI 8DC is an ideal solution for high-fidelity audio in a wide range of environments. Whether used in a dedicated home theater system or a commercial sound system, this loudspeaker delivers accurate, natural sound with deep bass and clear highs, elevating the listening experience in any space.
