Abstract:
A biplane line array speaker includes a line array of tweeters mounted substantially directly in front of a line array of woofers. The tweeter line array is arcuately shaped to provide controlled vertical dispersion above and below the boundaries of the speaker cabinet. The woofers are displaced from the tweeters in stepped manner. The speaker cabinet is a rectangular box, allowing efficient wall mounting in single or multiple unit columns. In multiple unit columns, the individual units acoustically couple to each other.
