Q Acoustics QI65C (pack of 2)

The Q Acoustics Qi65C stands out for its practical design, with just 79 mm mounting depth and a particularly ingenious fixing system. Featuring a pivoting tweeter and interchangeable magnetic grilles, it adapts to both home theater installations and Hi-Fi systems, even in humid environments.

Refined Design and Construction

The Qi65C sports a sleek design with its round grille measuring 232 mm in diameter, requiring a cutout of only 203 mm. Q Acoustics engineers have prioritized discretion with a low profile and quality materials. The magnetic grille attaches effortlessly and can be removed or swapped without dismounting the speaker. This approach even allows you to paint the grille to match your décor, with Q Acoustics providing dust covers for this operation.

The construction uses UL94 fire-retardant materials, ensuring safety. This certification, combined with moisture resistance, allows installation in a variety of environments, from living rooms to bathrooms. The light weight of 2 kg per unit makes handling easy during installation.

Balanced Acoustic Technology

At its acoustic core is a 165 mm polypropylene mid-bass driver paired with a 19 mm tweeter. This 2-way configuration delivers a frequency range of 75 Hz to 20 kHz with a sensitivity of 89 dB. The tweeter features a pivoting system, allowing you to adjust the directionality according to the room’s acoustics and your listening position.

The flat baffle design is a notable advantage: unlike traditional speakers, the Qi65C does not require a sealed enclosure behind it. This feature simplifies installation while avoiding unwanted acoustic interactions between nearby speakers in the same false ceiling. However, for full-spectrum sound reproduction, pairing with a subwoofer is still recommended, especially in a home theater setup.

User-Friendly Installation

Q Acoustics has paid special attention to ease of installation. The four “dogleg” clip mounting system is operated entirely from the front, eliminating the need for difficult access behind the ceiling. Tightening is done via front-facing screws, allowing precise adjustment without disassembling the unit.

The included cutting template prevents measurement errors. The spring terminals accept various cable types and can be operated with one hand—a practical detail during installation. This design even allows a skilled DIYer to handle the installation, though a professional is recommended for integration into a complex system.

Remarkable Versatility

The Qi65C excels in its adaptability. In stereo configuration, it is perfectly suited for Hi-Fi music listening, delivering clear mids and refined highs. Its 8-ohm impedance and 89 dB sensitivity make it compatible with most amplifiers, even those with moderate power.

In multi-channel setups, it naturally serves as an effects or ambient speaker in a home theater system. Its ability to operate in humid environments extends its use to kitchens and bathrooms—areas often overlooked in home audio installations.

Range and Available Variants

The Qi65C is part of a coherent family. The Qi65S version offers a square grille to match environments with strong geometric lines. The ST (Stereo) versions feature two tweeters and are suitable for small spaces requiring a stereo solution in a single speaker.

For outdoor installations, the CW models offer enhanced protection. The range also includes the Qi65CB, optimized for background music with higher efficiency, and the Qi80 for greater power needs. This diversity allows you to precisely tailor the solution to the requirements of each project.
