How do Audio Spotlight systems compare to other directional audio products?
Since Holosonics created the market for directional loudspeakers, a few traditional loudspeaker manufacturers have released systems that claim isolation and directivity. These systems take the form of speaker panels, arrays, and domes. It is important to note that all loudspeakers become more directional as their size increases. Therefore, a large speaker (or array) is more directional than a small speaker, and this is what these manufacturers are selling. Another trick that some manufacturers use is to specify directivity only at an unusually high frequency, where sound from all loudspeakers is more directional. These “directional” products feature 30 degrees or more of spread, with hardly a difference in level, and even then only at high frequency. Holosonics believes that “directional” sound should be comparable to light, or a laser – such as the 5 degrees of spread of the Audio Spotlight system. None of these products even remotely approach the directivity or sound isolation offere
