Overview

The Q Acoustics Qi65RP offers a discreet integration solution for hi-fi and home theater installations. This 6.5-inch 2-way in-wall speaker combines a 25 mm pivoting silk dome tweeter with a 16.5 cm woofer-midrange driver, all housed in a cabinet just 79 mm deep. Its removable magnetic grille and output level adjustment system allow for precise customization according to the listening environment.

Expertly Engineered Design

The Qi65RP is based on Nano Particle technology developed by Q Acoustics for its in-wall ranges. The woofer-midrange driver uses a polypropylene cone damped with nanoparticles, injection-molded. This manufacturing technique limits distortion and improves the handling of fast transients thanks to a high-power coil-magnet assembly.

The 25 mm silk dome tweeter stands out for its ability to pivot, allowing you to adjust the directionality according to the listening position. This flexibility is complemented by a three-position output level adjustment: -3 dB, 0 dB, and +3 dB, accessible from the front of the speaker.

The low-profile magnetic grilles make installation easy while preserving aesthetics. Their geometry has been optimized for the speaker’s frequency range, ensuring a balance between acoustic performance and visual discretion.

Acoustic Performance and Integration

With a power handling of 15 to 75 watts at 8 ohms nominal impedance, the Qi65RP is suitable for moderately powered amplifiers. Its sensitivity of 85 dB ensures proper sound reproduction even with low-powered electronics.

The frequency response extends down to 65 Hz at -3 dB, making this speaker an ideal complement to a subwoofer in a home theater setup. High-order passive crossovers ensure a smooth transition between drivers, while special attention has been paid to the midrange to preserve dialogue clarity.

Installation requires a rectangular cutout of 187 × 275 mm for a total depth of 79 mm, making it possible to integrate into most standard partition walls. The external dimensions of 219 × 306 mm remain compact for minimal visual impact once the grille is in place.

Frequently Asked Questions

What is the required mounting depth for the Qi65RP?

The speaker requires a minimum depth of 79 mm behind the wall, making it compatible with most standard walls equipped with metal studs.

Does the pivoting tweeter require any special adjustment?

The tweeter can be manually oriented to direct high frequencies toward the main listening area. This feature is especially useful for off-center installations or rooms with unusual shapes.

How does the output level adjustment work?

A switch accessible from the front panel allows you to adjust the high-frequency level in three positions: -3 dB to soften an overly reverberant environment, 0 dB for a neutral setting, or +3 dB to compensate for a dull acoustic.

Is the Qi65RP suitable for use as a center speaker?

While technically possible, Q Acoustics offers the Qi65LCR model specifically designed for this purpose, featuring two 16.5 cm drivers in a D’Appolito configuration for better horizontal directivity.
