Profile: Dakota Audio offers audio products. Our products include directional audio speakers, non-directional speakers, OEM-custom speakers and digital signage systems. The FA-501 36" overhead directional speaker directs the audio signal straight down. It produces a circular sound pattern enabling a variety of mounting positions from horizontally overhead, to mounting vertically on a wall, or under a grating in the floor. The AS-20 speaker reproduces ambient nature sounds. It also presents very low resonance.
