The 18W2000 can be used as a low bass or subwoofer component in either a reflex, bandpass or horn loaded configuration. It provides clean, linear, undistorted low frequency reproduction at very high
power levels.
The high excursion capabilities of the surround and suspension system, in conjunction with the Double Silicon Spider (DSS), enable the 18W2000 to achieve high levels of linear travel while maintaining full control of the moving mass.
The high quality curvilinear cone assures smooth response and exceptional strength with maximum reliability under high mechanical stress.
