"The avant-garde art of the past becomes the wallpaper of the future." This statement, from a new introduction by Francis Ford Coppola contained on the Apocalypse Now Final Cut Ultra HD Blu-ray release, ultimately explains the acclaimed director's motivation to revisit his Vietnam War epic, ranked number 30 on the American Film Institute's 2007 list of the 100 Greatest American Films, and create yet another cut after already having done so in 2001 for Apocalypse Now: Redux.

THE VERDICT
SDA-Pro, the latest refinement of Polk Audio's proprietary tech, elevates the performance of its impressive flagship speaker.

Many years ago (the early 1980s, to be precise), Polk Audio produced the first speakers to feature a technology it had developed called SDA (Stereo Dimensional Array). The idea behind SDA was to eliminate a problem called interaural crosstalk that's a necessary artifact of typical two-channel speaker configurations. Basically put, when listening in stereo, your left/ right ears hear not just sound emanating from the respective left/right speakers, but sound coming from the other speaker as well. According to Polk Audio, this has a constricting effect on the presentation, with the width, height, and depth of the stereo image coming across as a pale representation of what's actually contained on the recording.
