LG will bring three new 3D Home Theaters - the BH9420PW, BH9220BW and BH9520TW series - to North America next March.

The BH9420PW incorporates LG's own 3D Sound Zooming technology, which constantly synchronizes sound output with the location and movement of the on-screen 3D images on a CINEMA 3D Smart TV. 3D Sound Zooming is capable of generating variety of depth in sound based on a complex algorithm that analyzes the varying depth of numerous on-screen objects displayed on the 3D TV.

The 3D sound quality is enhanced further by the BH9420PW's 9.1 speaker system, which adds four Upright 3D Speakers to the 5.1 channels of a conventional home theater system. The four Upright 3D Speakers pump sound upward, ensuring that the vertical space is completely filled with sound. Meanwhile, a 360? Reflector inside each of the Upright 3D Speakers reflects sound in all directions.

Moreover, by applying LG's 3D effect DSP algorithm, the Sound Field Expansion technology further expands the horizontal sound field, and works in harmony with the Upright 3D Speakers to create a 360 degrees sound experience. Additionally, the audio "sweet spot" is further extended so viewers always feel as if they are right in the middle of the action, regardless of their location in a living room.

The BH9420PW is equipped with a Smart TV function. In turn, any ordinary 3D TV can have access to LG?s Smart TV ecosystem, which is composed of a variety of 3D content through various content services and apps, such as LG?s 3D Zone.

The BH9420PW will hit stores in March 2012.

More information will be provided by the company at the CES 2012 show.
