HIGH POWERED PRESICION
High Power Amplifier
The built-in amplifier is optimized for high impact at low frequencies. The fast response and high-power performance is perfect for movies or music.
No-Presses Paper Cones
A specially engineered 12” paper cone with increased self-damping properties offers an increased structural rigidity of the cone itself for a fuller performance and massive bass impact.

Copper Lined Vents
Reduce the magnetic distortion and also offers improved heat dissipation, letting the ZX-12 SUB rumble for hours but remain cool.
Low Pass Filter Slope
Continuously adjustable from 35Hz to 120Hz (@33dB) for seamless acoustic integration with your speaker’s performance.
High Sensitivity & Versatility
Low level inputs, output connections and a dedicated LFE input are provided. Additionally, the auto power sensor is sensitive enough to detect incoming signals of extremely low level for automatic activation of the subwoofer when required.
