Sonance IS8T – Invisible Series 8-Inch Speaker with Transformer

Product Overview

The Sonance IS8T is a 70V/100V transformer-tapped version of the IS8 Invisible Series in-wall speaker, combining the larger 8-inch woofer's output with tap flexibility for commercial distributed audio systems. It is built for integrators who need a fully hidden speaker driven from a 70V or 100V amplifier.

Product Description

Built on the same Invisible Series platform as the direct-drive IS8 sold through Sonance, the IS8T pairs an 8-inch carbon fiber Air Flex Woofer (191 in² diaphragm) and Wave Flex Drive Unit (29 in² diaphragm) with an internal 70V/100V transformer offering 60W, 30W, and 15W taps plus a 7.5W 70V-only tap. At 160 watts RMS and 4 ohms nominal in direct mode, with a 40Hz–30kHz frequency response and 86dB sensitivity, the IS8T is engineered for commercial background music and paging zones that still require an architecturally invisible finish. Like the rest of the Invisible Series, the IS8T installs into drywall, select plasters, wallpaper, leather, or wood veneer and accepts up to 3mm of topping compound. Its 180-degree sound dispersion (170° hemispherical up to 10kHz) provides even coverage across larger commercial rooms, and the Designed to Disappear approach keeps the finished wall or ceiling free of any visible grille. For multi-zone commercial deployments, pair the IS8T with 70V/100V amplification from Creation Networks.
