If a speaker has a very low set of dispersion numbers, what is it designed for?

A speaker with a very low set of dispersion numbers is designed for near-field or up-close use. This means that the sound emitted from the speaker is concentrated in a specific area, making it ideal for situations where the audience or listeners are in proximity to the speaker.

In this context, low dispersion indicates that the sound will not spread widely across a large area, but rather focus on a smaller, targeted audience. This is particularly useful in scenarios such as in vocal reinforcement for a small venue, where clarity and intelligibility at close range are crucial. Additionally, low dispersion speakers can help minimize sound spill into areas that don't require amplification, which can be beneficial in maintaining sound quality and preventing feedback.

The other contexts, like outdoor use or long-distance projection, typically require speakers with higher dispersion to effectively distribute sound over greater distances and broader areas. Therefore, the design and functionality of low dispersion speakers align specifically with near-field applications.
