The PhaseTech CI130 3-Way In-Wall Speaker delivers premium home theater and high-fidelity music performance in a discreet architectural design. Featuring dual 6.5-inch RPF flat-piston woofers, a dedicated 1.5-inch soft-dome midrange driver, and a 1-inch soft-dome tweeter, the CI130 is engineered to reproduce powerful bass, detailed vocals, and clear high frequencies without the need for traditional floorstanding speakers.
Part of the Phase Technology CI Custom Install Series, the CI130 incorporates driver technology also used in the manufacturer's Premier Collection. Its advanced Unicell Acoustic Treatment helps minimize unwanted sound interaction with the mounting wall, while the patented Positive Clamping System supports secure installation and controlled low-frequency performance.
With a frequency response of 36 Hz–22 kHz, recommended amplifier power of 20–250 watts, and a paintable magnetic micro-flange grille, the CI130 is ideal for dedicated home theaters, premium stereo systems, and custom residential audio installations.

Advanced 3-Way Sound Reproduction
The PhaseTech CI130 uses a three-way driver configuration to reproduce low, middle, and high frequencies through dedicated speaker components.
Two 6.5-inch RPF flat-piston woofers feature fiberglass and Kevlar composite cones with NBR surrounds. These drivers are engineered for controlled low-frequency response and reduced unwanted cone movement.
A dedicated 1.5-inch soft-dome midrange driver reproduces important vocal and instrumental frequencies, while the 1-inch soft-dome tweeter delivers high-frequency detail.
This combination makes the CI130 suitable for music listening and home theater applications where clear dialogue, precise imaging, and dynamic sound are priorities.
Unicell Acoustic Treatment for Improved Imaging
The CI130 incorporates Phase Technology's Unicell Acoustic Treatment around its midrange and tweeter assembly.
This technology is designed to absorb horizontally traveling sound waves and reduce unwanted acoustic interaction with the mounting wall.
By controlling these reflections, Unicell treatment helps improve imaging, clarity, and the overall listening experience.
The result is an in-wall speaker designed to deliver the precision expected from premium home audio equipment while maintaining a clean architectural appearance.
Patented Positive Clamping System
Secure installation is especially important for larger in-wall speakers that reproduce significant low-frequency energy.
The PhaseTech CI130 features a patented Positive Clamping System designed to hold the speaker securely in the wall opening and support consistent acoustic performance.
Its extruded aluminum clamping construction helps maintain a stable installation while minimizing unwanted movement.
The speaker's approximately 3.75-inch required mounting depth also provides flexibility for installations in suitable shared-wall applications, subject to available cavity space and building requirements.
Discreet Architectural Design
The CI130 includes a white, powder-coated galvanized steel grille with a magnetic micro-flange design.
The grille can be painted to coordinate with surrounding wall finishes, allowing the speaker to blend into home theater rooms, living areas, and custom entertainment spaces.
For new construction, the optional PhaseTech RB15 rough-in bracket can help installers prepare the wall opening before drywall installation.
