Focal 100 IWSUB8 Passive Subwoofer and Amplifier

The Focal 100 IWSUB8 system pairs an 8″ Polyglass passive subwoofer with a dedicated subwoofer amplifier, engineered for high-performance in-wall and custom installations. The passive bass-reflex subwoofer features a front vent and streamlined inner frame, ensuring precise, noise-free bass reproduction, while its compact depth allows easy installation with 16″ OC joists during pre-construction.

The 100 IWSUB8 subwoofer delivers natural, deep bass with a low-cut frequency of 30 Hz and a sensitivity of 89 dB (2.83V/1m), offering clean, controlled low-end performance. Its nominal 8 Ω impedance allows parallel connection of two subwoofers, creating a versatile solution for high-fidelity home audio systems.

Complementing the passive subwoofer, the 100 IWSUB8 Amplifier provides 200W peak and 150W continuous power at 4 Ω. Designed for seamless integration, the amplifier features detachable IEC power cord, LFE and line in/out connections, and dynamic power control with thermal, short-circuit, fuse, and over-current protection. It is capable of powering up to two 100 IWSUB8 subwoofers simultaneously, delivering balanced, reliable bass performance across music and home theater applications.

Together, the 100 IWSUB8 subwoofer and amplifier form a complete, high-quality solution for integrated audio systems. Designed for professional and residential installations, this combination ensures optimal complementarity with Focal and Naim systems for immersive, high-fidelity sound experiences.
