The Phoenix Gold ZX212PBS is a dual 12-inch slim passive subwoofer enclosure engineered to deliver deep, punchy bass in tight vehicle spaces. It is a sealed enclosure rated at 500W RMS and 1000W peak to provide clean low-frequency output for under-seat or shallow boot installations.

Built with high-strength MDF and a durable carpet finish, the ZX212PBS uses shallow-mount 12-inch drivers and spring-loaded terminal connections for secure amplifier hookup. Its low-profile design is intended for compact fitment where standard subwoofer enclosures are too large.
