Product Overview

The Sonance IS-ENCL-L-Narrow is a deeper version of the large sound isolating enclosure for the IS10 Invisible Series speaker, built to fit 16-inch on-center TJI joist construction. It gives integrators an isolation option for the IS10 on projects framed with engineered joists rather than standard lumber.

Product Description

Designed for the IS10 from the Invisible Series lineup sold through Sonance, the IS-ENCL-L-Narrow uses a deeper dimension than the standard IS-ENCL-L to accommodate 16-inch on-center TJI joist construction. It provides the same sound isolation objective as the standard large enclosure, helping contain the IS10 acoustic energy within its own room, but is sized to install cleanly within engineered joist bays common in modern residential and light commercial framing. Specifying this narrow version instead of the standard IS-ENCL-L avoids fit issues discovered during rough-in on TJI-framed projects. Combine it with a pre-construction bracket for a complete isolated IS10 installation.

Key Features

  • TJI Joist Compatibility — Fits 16-inch on-center TJI joist construction where the standard enclosure will not.
  • Deeper Profile — Modified dimension accommodates engineered joist framing while supporting the IS10.
  • Sized for the IS10 — Purpose-built to enclose the largest direct-drive Invisible Series speaker.
  • Enhanced Performance with IS10 — Engineered to optimize sound isolation specifically for the IS10 driver.

Typical Applications

  • New construction using engineered TJI joist framing
  • Premium listening rooms specifying the IS10 in TJI-framed ceilings
  • Multi-tenant or multi-story buildings requiring acoustic isolation
