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.
Claims16
A loudspeaker having a biplane arrangement of line arrays, comprising:
- a housing;
- a woofer panel disposed in the housing and comprising a first line array of low frequency transducers, each transducer having an acoustic center, the first line array having a first axis through the acoustic centers of the low frequency transducers, wherein the first line array has a staggered configuration such that the low frequency transducers are staggered with respect to the woofer panel;
- and
- a tweeter panel disposed in the housing and in front of the woofer panel, and comprising a second line array of high frequency transducers, each transducer having an acoustic center, the second line array having a second axis that is substantially aligned in front of the first axis, and passes through the acoustic centers of the high frequency transducers, and wherein there is a substantially uniform distance between the first and second axes.
A loudspeaker having a biplane arrangement of line arrays, comprising:
- a housing;
- a woofer panel disposed in the housing and comprising a first line array of low frequency transducers, each transducer having an acoustic center, the first line array having a first axis through the acoustic centers of the low frequency transducers;
- and
- a tweeter panel disposed in the housing and in front of the woofer panel, and comprising a second line array of high frequency transducers, each transducer having an acoustic center, the second line array having a second axis through the acoustic centers of the high frequency transducers, and wherein there is a substantially uniform distance between the first and second axes, and wherein the second line array has a substantially arcuate configuration.
