Soundbars are traditionally very simple things. A soundbar system will consist of a single bar and, depending on the make and model, a subwoofer. Sharp went a different way with their latest, offering you the ability to split the bar in half and have two vertical speakers.
Both the new HT-SL75 ($329) and HT-SL77 ($449) have the transforming feature and come complete with length adjusters and stands to support them while vertical. They each come with a subwoofer, but the sub on the SL77 ups the ante by going wireless. The SL75 is available now, while the SL77 won't hit until April.
