The Phase Technology CI160 is a 2-way in-wall speaker designed for custom home theater and architectural audio installations. It features dual 5.25-inch RPF flat-piston woofers and a 1.125-inch soft-dome tweeter, providing a space-saving alternative to conventional cabinet loudspeakers while maintaining a clean, built-in appearance.

Part of the Phase Technology CI Custom Install Series, the CI160 can be used in home theater and distributed audio systems where an in-wall speaker is preferred. Its tall, narrow enclosure fits between wall framing while the grille helps the speaker blend into the surrounding room.

With a specified 60 Hz–23 kHz frequency response, 116 dB maximum SPL, and recommended amplifier power of 20–200 watts, the CI160 is designed for applications requiring higher output from an architectural loudspeaker.

Dual 5.25" RPF Flat-Piston Woofers

The CI160 uses two 5.25-inch Phase Technology RPF (Rigid Polymer Foam) flat-piston woofers with fiberglass and Kevlar composite cones.

The dual-woofer configuration provides greater radiating area than a conventional single 5.25-inch in-wall speaker and contributes to the CI160's ability to reproduce music and home theater content at higher output levels.

The woofers incorporate NBR surrounds for controlled cone movement.

1.125" Soft-Dome Tweeter

High frequencies are reproduced by a 1.125-inch (28 mm) soft-dome tweeter.

Combined with the dual RPF woofers, the tweeter creates a 2-way loudspeaker system designed for both dialogue and music reproduction in custom-installed audio systems.

Designed for Home Theater

The Phase Technology CI160 can be incorporated into custom home theater installations where conventional freestanding or bookshelf speakers are not desirable.

Its in-wall design makes it suitable for applications such as:

  • Front left and right channels
  • Surround channels
  • Custom home theater systems
  • Multi-room audio
  • Media rooms
  • Architectural audio systems

For home theater applications, speaker placement and matching with the other loudspeakers in the system should be considered when determining the appropriate channel position.

60 Hz–23 kHz Frequency Response

The CI160 has a specified frequency response of 60 Hz–23 kHz ±3 dB.

For home theater installations requiring deeper low-frequency reproduction, the CI160 can be used as part of a system incorporating an appropriate subwoofer.

Up to 116 dB Maximum SPL

The Phase Technology CI160 is rated for a maximum SPL of 116 dB at 1 meter, with 150 watts specified for maximum output.

Phase Technology recommends amplifier power between 20 and 200 watts, providing flexibility when matching the speaker with compatible home theater receivers and power amplifiers.

Installation Dimensions

The CI160 requires a wall cutout measuring approximately 30.375 inches high × 7 inches wide and has a depth of 3.9 inches.

Those dimensions are worth keeping prominently on the page. People shopping for an architectural speaker frequently need to know whether it will physically fit an existing wall or planned installation.

Why Choose the Phase Technology CI160?

The Phase Technology CI160 combines dual 5.25-inch RPF woofers, a 1.125-inch soft-dome tweeter, 60 Hz–23 kHz response, and up to 116 dB maximum output in an in-wall loudspeaker designed for custom installation.

Its dual-woofer configuration makes it particularly useful when more output is required than would typically be expected from a compact single-woofer architectural speaker, while the in-wall design keeps the loudspeaker enclosure out of the room.
