Active Full-Range PA Speakers

It signifies the speaker's ability to reproduce a wide spectrum of frequencies, from low bass to high treble, without needing external subwoofers for basic applications.

Wider dispersion (90°) covers a larger area but can reduce clarity at longer distances; narrower dispersion (60°) focuses sound but may require more speakers for full coverage.

Line arrays are multiple speakers arranged vertically to create a coherent wavefront, offering controlled coverage and long throw; full-range speakers are a single unit for more localized sound reinforcement.
