WiSound RoomFill™ 3D-360° technology

Hear a realistic Soundstage — with consistent sound everywhere in the room.

WiSound RoomFill™ 3D-360° technology gives the 3D-Bar 8AT two unique advantages: • Realistic soundstage. Sound gains a natural sense of space and depth — not the flat presentation of a conventional soundbar. • Consistent result everywhere. The experience stays uniform across the whole room, not only in a narrow sweet spot.

Three-Directional Speakers — 6 Drivers

Hear a large soundstage in front of you, with width, height, and natural presence.

4 × 2.25″ front and side drivers + 2 × 2.5″ up-firing drivers work together so sound fills the room with detail and balance. • The front drivers give immediate stage presence, the side drivers extend the soundstage into the room, and the up-firing drivers add realistic height for the full Dolby Atmos experience. • The result: a vivid 3D soundstage with natural height and presence that opens up in front of you.
