Jamo C912 12" Front-Firing Polyfiber Woofer 400W Class D AMP Subwoofer

Outfitted with a 12” Front-Firing Polyfiber Woofer and 400W Class D amp, the Jamo C 912 Subwoofer perfectly melds premium low-frequency performance with a modern, luxurious design to create gorgeous furniture with exceptional acoustics.

  • A high-value, high-performance subwoofer solution designed specifically for home theater and 2-channel systems
  • Capable of 300W Peak Power for thundering bass
  • Front-firing tube port for an exceptional low-frequency extension with placement flexibility
  • Available in three premium finishes to match the Concert 9 Series II speaker line


The C 912 subwoofer boasts an injection-molded graphite (IMG) woofer cone, which is remarkably rigid - ensuring pure, pistonic motion with less cone break-up for clean, tight bass – while being exceptionally light, allowing the Concert 9 subwoofers to achieve some of the highest output in their class. The tube port features a flared design that minimizes port noise while providing exceptional low-frequency extension, and the front-firing positioning means you can put the subwoofer tight against a wall or in a cabinet.


Creating room-shaking bass requires an amplifier capable of providing accurate and ideal power requirements when needed. The Class D audiophile-grade amplifiers in the JAMO C 912 subwoofer provides astonishing, cinematic low end with headroom to spare.

Dual RCA inputs allow for connection to AVRs, processors, and integrated amplifiers while the WA-2 wireless kit compatibility provides for easy, cable-free installation. Continuously variable crossover filter and phase switch allows for fine-tuning of the subwoofer for optimal performance in your specific room.
