Overview
The Q Acoustics Qi80C represents the pinnacle of British expertise in in-ceiling speakers. This 2-way coaxial speaker is designed for audiophiles seeking a discreet listening solution without compromising on sound quality. With its reduced installation depth and innovative magnetic design, it integrates seamlessly into any home environment, from living rooms to home theaters and even damp rooms.
Design and Architectural Integration
The Qi80C stands out for its minimalist approach to architectural integration. Its total diameter of 281 mm with grille conceals a cutout of just 248 mm, thus optimizing visual impact. The magnetic grille is one of its most remarkable innovations: it snaps firmly into place without screws or visible fasteners, creating a perfectly smooth surface once installed.
The magnetic system also allows you to freely switch between round (included) and square (optional) grilles without removing the speaker. This flexibility is especially appreciated during renovations or decorative changes. The grilles are designed to be painted, including dust protection and a fabric backing to facilitate even paint application.
The construction uses UL94-certified fire-retardant materials, ensuring safety in all environments. This certification, combined with moisture resistance, allows installation in rooms such as bathrooms, greatly expanding placement possibilities.
Optimized Acoustic Configuration
The coaxial design of the Qi80C places the 19 mm tweeter at the center of the 203 mm woofer-midrange driver. This architecture eliminates the phase and directivity issues typical of traditional multi-way speakers, creating an ideal acoustic point source for ceiling diffusion.
The tweeter features a directional design, allowing you to aim the high frequencies toward the main listening area. This function is crucial in ceiling installations where the speaker cannot be physically angled. Adjustment is done manually during installation, offering a level of tuning precision impossible with fixed speakers.
The main driver uses a polypropylene cone, a material known for its linearity and resistance to deformation. This technology, inherited from Q Acoustics’ expertise in traditional speakers, ensures clear midrange reproduction and precise control of low frequencies.
Installation and Ease of Use
The installation of the Qi80C has been designed to simplify the installer’s work. The included cutout template ensures precise drilling, while the four-point “dogleg” mounting system provides secure support behind the wall or false ceiling. Tightening is done from the front by turning accessible screws, eliminating the need for delicate handling at the back.
The mounting depth of just 87 mm is a decisive advantage in modern constructions with limited technical spaces. This reduced dimension makes installation easy in most standard false ceilings without compromising insulation or requiring major structural modifications.
Gold-plated terminals allow for reliable, corrosion-resistant connections. Their design enables one-handed tightening, which is convenient for overhead installations. Polarity is clearly indicated, reducing the risk of wiring errors.
Sound Performance and Technical Specifications
The Qi80C delivers a power handling of 60 watts RMS at 8 ohms, making it compatible with most home amplifiers. Its sensitivity of 88 dB ensures sufficient sound levels even with moderately powered amplifiers, which is important in multi-zone installations.
The frequency response ranges from 55 Hz to 20 kHz, covering the essential audible spectrum. While the lower limit is typical for speakers of this size, it allows for balanced musical reproduction. For demanding home theater applications or bass-reflex listening, pairing with an active subwoofer is recommended.
The coaxial design offers naturally wide dispersion, ideal for covering large listening areas from a ceiling position. This feature makes it particularly suitable for open spaces or multi-seat configurations.

Frequently Asked Questions
What is the difference between the standard Qi80C and the Performance version?
The Performance version delivers 80W versus 60W, requires 97mm depth versus 87mm, and includes a tweeter level adjustment (-3dB, 0dB, +3dB). It also offers higher sensitivity (90dB vs 88dB) and a slightly improved frequency extension.
Can several Qi80C speakers be installed in the same room?
Yes, but Q Acoustics recommends segmenting the space behind the speakers to prevent the rear waves of each speaker from interfering with each other. Minimal spacing and basic acoustic isolation are generally sufficient.
Is the speaker really moisture-resistant?
Yes, it is designed for humid environments such as bathrooms. However, avoid direct exposure to water splashes. The certification ensures safe use under these conditions.
