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 Sound 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.

Room Adaptive Dynamic Equalization

Enjoy the most advanced sound experience, with 3 types of Dynamic Room Equalization:

1. 3D-360° Spherical Room Adaptive Equalization
• natural and pleasant sound
• rich feeling of space everywhere in the room,
• without the narrow sweet spot of the conventional speakers

2. Dynamic Equalization
• full sound with dynamic Bass
• automatically adjusted
• even at very low Listening Levels

3. Reflections Gain Equalization
• Listen without Distortion
• without reflection colorations from walls and furniture

WiBass™ — Deep & Powerful Bass

WiBass™ Smart Bass DSP keeps bass deep, clean, and controlled at every volume.

• At low volume, bass stays full and present.
• At high volume, WiBass™ helps control distortion, so movies, games, and music keep their impact without overloading the room.

4.1.2 Channels

Enjoy superior acoustic experience than the common 3.1.2 and 2.1.2 soundbars with height channels.

4: refers to the number of traditional surround speakers (front. center, surround)
1: refers to the number of powered subwoofers
2: refers to the number of up-firing speakers

Wireless 8″ Subwoofer

Hear and feel deep bass down to 30 Hz — without cables, with placement freedom.

The 8″ wireless subwoofer moves over 2× more air than a typical 6.5″, for deeper, more powerful bass that fills the room.

• Because it's wireless, you can place it wherever fits your space best — beside the cabinet, in a corner, or further back for an even bigger effect.
• It works seamlessly with the soundbar through WiSound DSP for an even, balanced response across the entire frequency range.

Perfect Sound Everywhere in the Room

Enjoy rich, natural, and perfectly balanced sound — wherever you sit.

• WiSound technology expands the traditional "Sweet Spot" to the entire room, projecting sound evenly in 360°.
• Sound creates natural reflections to enhance clarity, depth, and realism.
• The result is a spacious, lifelike, and dynamic soundstage — with perfect sound everywhere in the room.

Sweet Spot

Hear clear, balanced sound across the whole room — not only in one “perfect spot.”

Every recording is mixed in a studio. The engineer sits at one precise position, at the center of an acoustically optimized room. That position is called the sweet spot. Your living room is not a studio, and not everyone on the couch sits in the same place.

Traditional audio systems with speakers spread across the room reproduce that feeling only in a narrow zone. Even the most advanced virtual-stereo and virtual-surround systems are very sensitive. A few centimetres off and the balance is gone.

It is true that no soundbar and no single speaker can match, at the sweet spot, the stereo image of a pair of top-class monitor speakers placed far apart at the corners of a triangle with the sweet spot. But with WiSound RoomFill™ and 4.1.2 channels, the 3D-Bar keeps the stereo image stable and natural — for everyone in the room, not just one listener.
