SB1211
12″SUBWOOFER
- 2+2Ω nominal impedance
- 2+2Ω minimum impedance
- 2*2200W RMS capacity
- 2*1100W AES capacity
- 85 dB sensitivity
- 49-800 Hz response

SB1211 is driven by great energy, the shock is born from the “sound“.This flagship woofer unleashes the potential of your system. It can easily cope with extreme dynamic output. It has a strong, well-layered low-frequency performance. The large-size structure brings stronger bearing capacity and excellent heat dissipation performance, escorting the extreme output. The low–frequency fierce general born for large systems, tough, is its background color.

This series started to be developed as early as 2016, but it was not available until 2017 because when our engineers strived to achieve the best quality. Our company also invested a lot of money to Customized the mold because the common materials on the market could not meet the requirements. So from the design to the materials used, it took all the engineers’ efforts. Good parameters are obtained from the design, there is no sewing process. The process of research and development will not be revealed, I believe that a slight understanding of the picture can feel the overall quality of the product, is indeed a rare speaker unit, do not miss a good partner!
