The Q Acoustics QI65SP is the square-grille variant of the QI65P Performance in-ceiling speaker from Q Acoustics' Q Install range. Sitting above the entry-level QI65ST and alongside the circular-grille QI65CP, the QI65P series delivers a step up in sonic refinement for whole-home audio and multi-room installations where sound quality matters as much as visual discretion.

Driver Configuration & Crossover

The QI65SP pairs a 165mm woofer with a 25mm (1-inch) swivel tweeter, allowing the high-frequency output to be aimed towards the primary listening position after installation. A crossover-mounted HF adjustment switch provides ±3dB of treble control, enabling fine-tuning to suit different room acoustics and ceiling heights without the need for external equalisation.

Installation & Construction

Designed for straightforward retrofit and new-build installations, the QI65SP requires a 203mm ceiling cutout and sits just 79mm deep behind the ceiling surface. Four front-mounted clamps secure the speaker from below, eliminating the need for rear access during fitting. Push-open speaker terminals allow single-handed cable connections, and an installation template with cutter guide is included.

The magnetic grille system clips into place without visible fixings, delivering a clean, flush finish. The square grille option suits rooms with angular design cues where a circular grille might look out of place.

Moisture Resistance & Safety

The QI65SP's housing is moisture-proof and constructed from UL94 flame-retardant materials, making it suitable for installation in kitchens and other moisture-prone areas where conventional speakers would be at risk.
