Subwoofer Radiators
Find subwoofer passive radiators at Sound Approach for compatible speaker and subwoofer projects, with components designed to extend low-frequency performance without requiring an additional powered driver.
A subwoofer passive radiator is an unpowered diaphragm that works with an active woofer and the air pressure inside a speaker enclosure. Unlike a conventional powered subwoofer driver, a passive radiator does not use a voice coil, magnet, or direct electrical connection to an amplifier. Instead, movement of the active driver creates pressure changes inside the cabinet that cause the passive radiator to move and contribute additional low-frequency output.
Passive radiator designs can provide an alternative to a traditional bass-reflex port, particularly when enclosure dimensions make the required port size or length impractical. When properly matched and tuned, a radiator can help extend bass response while avoiding some of the airflow noise associated with ports. Radiator size, moving mass, excursion capability, enclosure volume, tuning frequency, and compatibility with the active driver are all important factors when designing or servicing a passive radiator speaker or subwoofer system.
Sound Approach offers subwoofer radiators for compatible replacement, custom speaker, and subwoofer applications. Compare radiator diameter, dimensions, mounting requirements, excursion, mass, and manufacturer specifications carefully to select a passive radiator appropriate for the driver, enclosure, and intended low-frequency tuning of your project.
