The Digitally Steerable Array speaker is one of the newest technologies during this year. This type of loudspeaker is relative infancy compared with other sound reinforcement technology. Therefore it still can’t easy be find in the big live concert or arena. According to this article, this unique audio animal is primarily intended for small-to-medium size commercial and house-of-worship applications where priorities include intelligibility, controlled dispersion and aesthetics. What’s the benefit of “Steerable” function? According to the last week article I posted. When we use more then one speaker in the same room at same time will cause comb filter happen and depend on the position you stand will have will listen frequency lose.
That is why have a lot of tricks to prevent comb filter happen.
Ex: Line array especially when we use Sub. We use the highest frequency that the Sub has and known that highest frequency wavelength and multiply 2/3, that will be the distance between speaker and speaker you should put.
The other method is by using End fired array
The last speaker set “0” delay time and the speaker before the last speaker increase the delay time and so on. The purpose is put all sound together and become very big sound wave.These skills are too difficult for consumers but if we have Digitally Steerable Array speaker that will be very easy. We can remote the position where we want without moving the cabinet. (Think of it like your head is facing forward and is stationary, but your eyes are shifting up and down and back and forth to focus your vision on different areas of a room)
Most DSA have DSP system and amp inside of the speaker. Here is a company just release the kind of product
Hey Chiache. You provided important and value information about Steereable Arrays. Also the info about double stacked subs. The first time that I saw this setup, I asked myself about how it works and for what it is for. Thanks for the info.
