LATEST ADDITIONS

TRADITIONAL two-channel audio never went away. But there’s no denying that since the early ’90s, stereo has been overshadowed by home theater. Most of the audio industry devoted most of its effort to adding more speakers, more channels of sound, and more complexity to our systems.

While the hype at CES this year was all about OLED, 4K, and bigger TVs, a quiet revolution began in the interaction department. LG and Samsung both announced new ways to control TVs using facial and speech recognition, or even just a wave of your hand.

A front-projection system is usually the display of choice for serious home-theater enthusiasts. But such systems are more expensive than most flat panels and rear-projection TVs, especially when you consider the cost of a good screen. So finding a low-cost projector that performs well is the Holy Grail for those who want a true home cinema without breaking the bank.

INEVITABLY, WHEN something cool comes out, it will influence everything that immediately follows. That’s what happened with Avatar. In 2009, we all went to see it in 3D, and the following year stores were packed with 3D TVs and 3D Blu-ray players.
