In-Ceiling Speaker Q Acoustics Qi65CP

Overview

The Q Acoustics Qi65CP combines acoustic performance with perfect architectural integration, appealing to both Hi-Fi enthusiasts and home cinema fans who want to preserve the aesthetics of their interiors. With an installation depth of just 79 mm and an innovative mounting system, it can be installed in virtually any ceiling, including the most constrained spaces.

Design and Perfect Architectural Integration

The Qi65CP’s minimalist approach reflects Q Acoustics’ philosophy: to make the physical presence of the speaker disappear, leaving only the sound. Its external diameter of 232 mm with a white circular grille blends seamlessly into the ceiling, while the paintable magnetic grille allows for complete customization to match your décor.

The “flat baffle” design is a remarkable technical feature: unlike many in-ceiling speakers, the Qi65CP does not require enclosure in a closed rear volume. This greatly simplifies installation and allows integration into ceilings where rear space is limited or shared with other equipment.

The choice of materials meets modern safety requirements with a UL94 fire-retardant rating, ensuring compliance with the strictest building standards. This certification is especially reassuring for high-end commercial or residential installations.

Installation Revolutionized by Simplicity

Q Acoustics has completely rethought the installation process with a “dogleg” mounting system that is operated exclusively from the front. This innovation eliminates awkward handling behind the ceiling: four front-accessible screws control the mounting claws, ensuring a firm and lasting hold.

The included cutting template guarantees precise drilling of a 203 mm diameter hole, while the gold-plated terminals connect with one hand thanks to their push-open system. This user-friendly design transforms a traditionally tedious installation into a process accessible to both professional installers and experienced DIYers.

The 79 mm mounting depth opens up installation possibilities even in the thinnest ceilings. This compactness does not compromise performance: the internal chassis design optimizes the acoustic volume required for the 165 mm speaker to function properly.

Acoustic Performance and Versatile Use

The 165 mm woofer and 25 mm tweeter deliver a frequency response from 70 Hz to 20 kHz, covering the essential audible spectrum with a sensitivity of 90 dB. This 2-way configuration easily handles 80 watts RMS, providing enough dynamics for demanding listening even in medium-sized rooms.

The pivoting tweeter is the Qi65CP’s key asset: its rotation allows you to direct high frequencies toward the optimal listening area, compensating for the placement constraints inherent to ceiling speakers. This flexibility is especially valuable in asymmetrical installations or rooms with complex shapes.

The Qi65CP’s versatility extends from simple stereo systems to the most elaborate multichannel home cinema setups. For Hi-Fi, an active subwoofer will advantageously extend the bass response, while in home cinema, several Qi65CPs can form a fully invisible surround system.

Extensive Range and System Compatibility

The Qi65CP is part of a broad family offering the same concept in several variants. The Qi65S version features a square grille to match geometric lighting, while the ST (Stereo) versions include a double tweeter for single-speaker stereo use.

The outdoor Qi65CW versions extend possibilities to patios and covered gardens, maintaining the same performance in a chassis treated for outdoor use. This product line consistency makes mixed indoor/outdoor installations easy.

Amplifier compatibility remains universal thanks to the nominal 8-ohm impedance and high sensitivity. These features suit both traditional Hi-Fi amplifiers and modern multiroom systems or home cinema receivers.

Frequently Asked Questions

Can the Qi65CP be installed in a bathroom or kitchen?

Absolutely. The moisture resistance certification allows installation in damp environments without risk of damage. The sealed chassis protects internal components from steam and splashes.

What is the minimum ceiling depth required?

A depth of 79 mm is sufficient, allowing installation in most standard ceilings. This compactness does not affect performance thanks to the flat baffle design, which does not require a closed rear volume.

What is the difference between the CP and S versions?

The CP version has a circular grille, while the S version features a square grille. Acoustic performance is identical; only the aesthetic differs to suit decorative preferences.
