Design:12 independent cabinets of 10 4 inch drivers (off the shelf). Each cab will be wired to allow massive parallel (6 cabs per side), or independent drive (24 50 watt channels, each fed by a dsp block to allow spacial ITD/IID variation side to side as well as up/down.
10 independent lines of 20 tweets each. Same kind of feed system.
Horizontal directivity is two fold, physical rotation of each cab, as well as temporal phased array style if I drive it with individual amps under dsp control.
It'll also serve double duty, as I also want to use them for the back channels in a 450 seat venue, but do not have the distance from crowd I would need for a 12 inch driver runnin 400 watts. Using a large spread of smaller drivers keeps the spl much lower 6 feet from the cabs, so the people sitting in front of it aren't made uncomfortable..it's easy blowin them away with a single driver at high power, but that's not the desired end result.
Cheers, John
