This is very interesting,
I have done it for Live showīs, in Pro-Audio, but Itīs a great solution for High-Profile Home Systems.
As We know, the low Frequencies are Omnidirectional ( They expand 360 degrees from the source ) and Itīs almost impossible to control their directivity because You would need huge horns,
the last thing that You want is energy reflecting in the walls, and We all know that subīs do that perfectly.
So, if You want to have some control, The first thing You need, is 2 subīs, and one DSP ( Digital Signal Processor ) to make one delay time alignment.
Itīs kind of simple, but this is for those guyīs with a big room.
One sub is in front of the other ( Very F Weird, right ? ) and then You have to make some adjustments in delay and phase.
The result is a great punch in the front, crystal clear bass, and almost no energy in the back of the array, resulting in less reflections, and greater sound.
In The images You can see a tipycal array of 2 subs, and the array with one in front of the other and the processed sub working, projecting almost all of the energy to the front.
The images are Plant views, and I Will be more than glad if You request some of this info, as well as more graphics with different freqīs.
The other picture, is an array that we did Live, with lots of subīs.
So You can see it actually works.
