Control4 Triad In-Room Silver LR-H – It can be difficult and expensive to pull wires through walls and ceilings, especially in existing home theater installations, but Control4’s Triad speaker solutions simplify Atmos. The In-Room Silver LR-H helps to overcome these challenges by combining two in-room speakers into a single cabinet. An easy upgrade to Atmos, the In-Room Silver LR-H features a front-firing speaker system, as well as a height channel that fires focused and localized sound that reflects off the ceiling.
