The new home theater in-a-box gives you 3D Sound Zooming and a nice wide sweet spot.
We've got to give it to LG, their new home theater system seems like a slick setup. It sets itself apart from the rest by offering 9.1 channels of audio instead of the usual 5.1 or 7.1. Another significant difference between the BH9420PW and most HTiB solutions is that LG doesn't just give you small speakers - you'll get four floorstanding speakers in addition to the satellites.
LG's BH9420PW home theater system offers a feature called 3D Sound Zooming that syncs sound output with whatever's happening in the 3D movie you're watching. LG specifies that this will work with LG Cinema 3D TVs, but it's unclear whether or not this feature is compatible with other sets.
You'll be able to get your hands on the BH9420PW this March, but a price has not yet been announced.
