The purest and most tangible audio experience



The VS28 subwoofer is internally loaded with two 18-inch speakers. It has powerful impact, sensitivity and low frequency performance, with an H-shaped vent progressive shape on both sides, allowing laminar airflow and reduced turbulence noise. These integrated features help improve work levels while also improving Low frequency efficiency.  
VS28 is the recommended ultra low frequency supplement for V15 or V12, V10 line arrays. The VS28 operates at 25Hz. The long stroke unit combined with the left and right H-type inverter holes helps to deliver high sound pressure levels with low distortion. The VS28 provides standard or cardioid directionality combined with physical deployment and appropriate presets.  
The VS28 enclosure is made of Baltic birch plywood to ensure maximum acoustic and mechanical integrity.  
The VS28 is driven and amplified by a C15 or VDA18 power controller. Protect and optimize different configurations of the speaker system, including cardioid.
