Fully steerable loudspeaker arrays are technically feasible but priced out of existence

Evidence

It is intriguing to contemplate having an array loudspeaker capable of broadband image stabilization without having the accompanying multidirectional radiation: a fully steerable array. Today’s technology using many drivers, each independently driven and signal processed, would be capable of radiating almost any directional pattern controlled by a handheld wireless device. Products of this kind are entirely feasible, and if offered in the marketplace, very high prices can be anticipated, which is likely why they do not exist. Sitting in the stereo seat can be a significant cost-saving decision. — Toole, Floyd E, Sound reproduction- the acoustics and…, 431
