Overview

Focal 100 ICW8 2-Way In-Wall / In-Ceiling Speaker

2-Way Coaxial Architectural Speaker • 8" Polyglass Driver • Adjustable Inverted-Dome Tweeter • 90 dB Sensitivity • In-Wall or In-Ceiling

The Focal 100 ICW8 is the largest model in Focal's 100 Series ICW range, combining an 8-inch Polyglass mid-bass driver with an adjustable inverted-dome tweeter. Designed for both in-wall and in-ceiling installation, it delivers greater low-frequency extension and output than the smaller ICW5 and ICW6 while retaining a discreet architectural footprint. Focal

Its combination of an 8-inch driver, 53 Hz to 23 kHz response, 90 dB sensitivity and 150-watt amplifier compatibility makes the 100 ICW8 particularly well suited to larger rooms, stereo zones and architectural home theater systems. Focal

8" Polyglass Driver

The 100 ICW8 uses a substantial 8-inch Polyglass mid-bass driver.

Focal's Polyglass technology applies fine glass microbeads to a cellulose-pulp cone, increasing rigidity while retaining useful damping characteristics. The larger 8-inch driver gives the ICW8 a 40 Hz low-frequency point at -6 dB, providing significantly deeper extension for an architectural speaker. Focal

Adjustable Inverted-Dome Tweeter

Focal's inverted-dome tweeter provides wide dispersion for more consistent coverage throughout the listening area.

Treble output can be adjusted -3 dB, 0 dB or +3 dB, allowing the installer to compensate for room acoustics, speaker location and reflective surfaces. Focal

In-Wall or In-Ceiling Installation

The 100 ICW8 can be installed in either a wall or ceiling, allowing one speaker platform to serve stereo, distributed-audio and home theater applications.

Despite its 8-inch driver, mounting depth is only 4.19 inches, helping simplify integration into residential construction. Focal

Moisture-Resistant Polyglass

Focal tropicalizes the Polyglass cone for improved resistance to humidity.

This allows the 100 ICW8 to be used in appropriate damp residential spaces, including bathrooms, while maintaining consistent 100 Series performance throughout the home. Focal

Circular or Square Grilles

Focal offers ready-to-paint magnetic grilles in circular or square formats, allowing the speaker to better match the architecture of the room.

Once installed and painted, the 100 ICW8 maintains a clean, low-visibility appearance. Focal

Focal specifies 90 dB sensitivity, 8-ohm nominal impedance, 6.9-ohm minimum impedance and 25 to 150 watts recommended amplification. The 8-inch Polyglass driver reaches 53 Hz ±3 dB and 40 Hz at -6 dB. Focal

Built for Larger Architectural Audio Systems

Within the 100 ICW family, the ICW8 is the choice when greater output and deeper bass are priorities. Its 8-inch driver makes it especially attractive for larger living areas, higher-output whole-home audio zones and home theater applications.

For systems requiring dedicated low-frequency reinforcement, Focal recommends pairing the 100 Series with the 100 IWSUB8, while Naim's CI electronics provide matching amplification options. Focal
