Passive speakers are professional loudspeakers that require an external power amplifier to operate. Widely used in public address (PA) systems, professional audio installations, auditoriums, conference halls, and commercial spaces, passive speakers offer flexible system design and high sound quality.

Unlike active speakers, passive speakers do not contain built-in amplifiers, allowing system designers to select amplifiers based on power, zoning, and redundancy requirements. Passive speakers are available in various formats, including ceiling speakers, wall mount speakers, column loudspeakers, horn speakers, and subwoofers, making them suitable for both indoor and outdoor applications.

Compatible with 100V line and low-impedance systems, passive speakers provide efficient audio distribution over long cable distances and reliable performance in fixed installations. Known for durability and scalability, passive speakers are a preferred choice for professional PA systems where centralized amplification and long-term reliability are essential.
