Dual drivers, twice the fun. 1723 Subwoofer 2S offers an exceptional balance between perfect music reproduction as well as sheer bass depth and output. Utilising two of our proprietary 13.8” drivers, driven by our smart 1200W RMS Avalanche 1200 IQ amplifier that offers ample adjustability for any setup. The cabinet is sealed and made of HDF, and is sized to provide an optimally damped system that produces deep, undistorted musical bass with a complete lack of smearing or coloration. The dual opposing, force-absorbing driver layout delivers clean, deep bass, without cabinet movement subtracting anything from the driver output. Literally startling dynamics. We believe this the world’s best subwoofer for music. At any price level.
