With its 100 Series range of integrated equipment, Focal delivers concrete, quality solutions to amplify your home. Innovating a little bit more each day, the brand continues to expand its range of products and is proud to introduce for the very first time a built-in subwoofer: 100 IWSUB8, along with a dedicated amplifier: 100 IWSUB8 Amplifier.

For over fifteen years, Focal has been working on developing quality integration products to help bring the Focal sound experience into the living spaces. Today, the globally renowned French brand presents a new bass enclosure, specially designed for in-wall mounting, along with an amplifier. Designed to deliver a unique ambiance and sound coverage, blending in seamlessly with the chosen setting, these products are the ideal add-on to a 100 Series audio-video setup, providing unrivalled value for money.

Including an 8″ Polyglass speaker driver and a front vent with a streamlined inner frame to guarantee no-noise operation, Focal 100 IWSUB8 high-power passive bass-reflex subwoofer can be installed during pre-construction of the walls using 16″ OC studs. With a shallow in-wall depth (33/8“), a high-quality bass reproduction (bass cut-off frequency: 30Hz to -6db) and covered with a low profile magnetic grille, which can be painted, it is as high-performance as it is discreet. In a bid to design the very best products and combinations of audio solutions, Focal has developed a dedicated easy-install amplifier specially tailored for this subwoofer, that can also be rack-mounted if desired: Focal 100 IWSUB8 Amplifier. Capable of powering up to two subwoofers connected in parallel, it delivers 200watts of power over 4ohms. If it’s true that sometimes “the walls have ears”, then your ears will never have loved your walls more…
