PhaseTech CI6.0X 6.5-Inch In-Ceiling Speaker with Absolute Phase Crossover

The PhaseTech CI6.0X 6.5-Inch In-Ceiling Speaker is a premium architectural loudspeaker designed to deliver detailed, natural sound while maintaining a clean, unobtrusive appearance. Part of the Phase Technology CI Custom Install Series, the CI6.0X is engineered for residential home theater systems, media rooms, and distributed audio installations where sound quality and discreet speaker placement are equally important.

Featuring Phase Technology's Absolute Phase™ crossover network, the CI6.0X is designed to maintain accurate phase relationships for consistent, lifelike sound reproduction. Its 48 Hz to 22 kHz frequency response, 90 dB sensitivity, and 8-ohm nominal impedance make it a versatile choice for compatible residential audio systems.

The speaker also features a white, paintable magnetic steel grille that provides a finished architectural appearance. Whether used for front, center, or surround-channel reproduction in a home theater or for music playback throughout the home, the PhaseTech CI6.0X combines installation flexibility with performance-focused speaker engineering.

6.5-Inch In-Ceiling Speaker for Home Theater and Music

The PhaseTech CI6.0X is designed for custom installations where traditional floor-standing or bookshelf speakers may not be practical.

Its in-ceiling configuration allows the speaker to be integrated into the room while preserving floor space and maintaining a clean appearance.

The CI6.0X can be incorporated into properly designed home theater systems for front, center, or surround-channel applications. It is also suitable for residential music systems where consistent audio reproduction is desired across multiple rooms.

For home theater installations, speaker positioning and system configuration should be selected according to the room layout and the intended listening positions.

Absolute Phase™ Crossover Technology

The PhaseTech CI6.0X features Phase Technology's Absolute Phase™ crossover network, a design intended to improve the timing and phase relationship of the speaker's reproduced frequencies.

Proper phase integration is important for maintaining natural sound reproduction, especially when listening to dialogue, vocals, and complex musical passages.

By incorporating Absolute Phase crossover technology, the CI6.0X is engineered to provide a cohesive listening experience for both movie soundtracks and music.

This makes the speaker a practical choice for installations where clarity, tonal consistency, and accurate audio reproduction are priorities.

Wide Frequency Response for Detailed Audio Reproduction

The CI6.0X offers a manufacturer-specified frequency response of 48 Hz to 22 kHz (±3 dB).

This range allows the speaker to reproduce a broad spectrum of musical and home theater content, from lower-frequency instruments and effects to detailed upper-frequency information.

With a published sensitivity of 90 dB at 2.83V/1m and a nominal impedance of 8 ohms, the CI6.0X is designed for use with appropriately matched residential amplifiers and AV receivers.

For home theater applications requiring extended low-frequency effects, a compatible powered subwoofer may be incorporated into the system.

Magnetic Paintable Grille for a Clean Architectural Finish

The PhaseTech CI6.0X includes a white magnetic steel grille designed to provide a neat, finished appearance in residential ceilings.

The powder-coated, galvanized steel grille is paintable, allowing installers to coordinate its appearance with the surrounding ceiling.

Magnetic attachment simplifies grille installation and removal compared with designs requiring visible fasteners.

The CI6.0X is a suitable choice for living rooms, media rooms, and other finished residential spaces where the speaker should blend into the room rather than dominate its appearance.

Designed for Custom Residential Audio Installations

As part of the Phase Technology CI Custom Install Series, the CI6.0X is intended for integrated residential sound systems.

Its combination of architectural styling, an 8-ohm design, and high-quality audio components supports a variety of installation configurations.

Applications include individual home theater channels, stereo music systems, and multiroom audio systems using compatible amplification.

The speaker's gold-plated binding-post connections provide an electrical interface for connection to suitable speaker wiring.

Installers should confirm the mounting requirements, ceiling clearances, and amplifier compatibility before installation.
