12SB1800

12″SUBWOOFER
  • 4+4Ω nominal impedance
  • 3.6+3.6Ω minimum impedance
  • 2*1500 RMS capacity
  • 2*750 AES capacity
  • 82 dB sensitivity
  • 39-1000 Hz response

This series began development in 2016 and was launched in 2017 after our engineers worked tirelessly to ensure top quality. Significant investment went into customizing the mold, as standard materials couldn’t meet our requirements. From design to material selection, every detail reflects the engineers’ dedication. With precise mechanical vibration damping, optimal q-value, and a special polymer material that balances lightness, stiffness, and damping, this speaker unit achieves high sensitivity and smooth, natural sound reproduction. Its high sound density, dynamic control, and clarity make it a remarkable speaker unit you won’t want to miss!
