There's a reason Bang & Olufsen is calling its new 4K TV the "one that moves." The BeoVision Avant will follow you around the room, and special stands and mounts change its position. But B&O is really hoping that it has created such a high-end viewing experience that the TV will move you to part with about $8,000 — the retail price of the 55-inch TV. And that doesn't even include one of those fancy stands. During a demonstration, B&O was persuasive that it had created a unique TV. Although motorized stands for TVs have existed for decades, the company's design makes them silent and elegant, and the wall mount — which can fold the TV outward as much as 90 degrees — barely makes the TV stick out. Additionally, the TV has an audio system just as fancy and high-tech as the set itself. When you turn it on, the speaker array slowly emerges from the bottom of the TV (getting the "move" theme yet?). It includes a trio of tweeter/midrange pairs as well as a 4-inch woofer. A 6-inch bass driver is in back. Playing Michael Bublé and Nelly Furtardo's version of "Quando Quando Quando," the TV was more than capable of filling a large room with sound the TV was more than capable of filling a large room with sound, and that was even before the woofers were engaged. When they were, the set could get impressively loud, even in an event space. You can also reprogram the TV speakers to work with a more extensive room system. The moving stands, which start at $895, complete the experience. A circular floor stand (which B&O calls the "planet") can both rotate itself as well as the TV's angle on it, opening up lots of flexibility for viewing. You can preprogram your own optimal positions, which the TV will move to at the touch of a button. The wall mount works similarly, angling the TV from side to side, able to position it at up to a right angle, assuming your walls allow it. The table stand doesn't rotate, but can elevate the TV a few inches when it's turned on.
