WH1 Single 18″ Low Frequency Horn



This no-compromise folded horn is powered by an 18” woofer with a 4.5” voice coil. The horn is a curved gradually expanding surface with no abrupt angles to cause discontinuities in airflow. All unused spaces in the cabinet are filled with polyurethane foam. The result is breathtaking because the power of this cabinet is absolutely incredible.
