The Sonance IS15W is an Invisible Series subwoofer built to disappear completely into a wall, using dual 15-inch carbon fiber woofers behind a flush, paintable surface that accepts drywall finishing, select plasters, wallpaper, leather, or wood veneer with up to 3mm of topping compound — so once installed and finished, no speaker grille or cabinet is visible at all. Sonance's Motion Flex Technology, combining an acoustically isolated baffle with an Air Flex Woofer and Wave Flex Drive Unit, delivers real low-frequency output down to 30Hz despite the flat, in-wall form factor, handling 250 watts RMS at 93dB sensitivity. It's designed for in-wall use only and fits standard 16-inch on-center stud construction, making it a purpose-built solution for custom home theater or listening rooms where any visible subwoofer — even a grille — isn't acceptable. Backed by a 15-year limited warranty through authorized dealers, it's aimed at high-end custom installations rather than DIY retrofits, where architectural invisibility matters as much as bass performance.
