360 Spatial Sound Mapping – These wireless rear speakers work with compatible soundbars to create multiple phantom speakers throughout your space. Surrounded by an optimized sound field, every sound hits with intensity. Hear sound from overhead – A large 80 mm up-firing speaker reflects sound off the ceiling, creating natural reflections from above and behind. It enriches the height layer in 360 Spatial Sound Mapping, deepening the sense of scale. Clear, expansive sound – An aluminum diaphragm reduces noise for purer sound. Tweeter, woofer, and up-firing speakers open up the soundstage, with a passive radiator deepening the bass for space, distance, and realism. Enhanced Wall-Mounting Capability – Included wall-mount bracket provides swivel adjustment, enabling precise speaker angling toward the listening position for accurate sound alignment.
