D&B Audiotechnik Z0538.100 Vi-SUB Weather-Resistant Subwoofer
• High-performance cardioid design for precise low-frequency reproduction
• Weather-resistant construction with IP55 rating for reliable use in various conditions
• Versatile installation options to enhance your audio setup
The Vi-SUB is an actively driven high-performance cardioid subwoofer. It features integrated rigging equipment and shares the same acoustical and visual design as the Vi-GSUB. It has two long excursion neodymium drivers - an 18' driver in a bass-reflex design facing forward and a 12” driver in a two-chamber bandpass design radiating to the rear. This creates a cardioid dispersion pattern that reduces unwanted energy and provides accurate low-frequency reproduction. You can use it to supplement Vi8 and Vi12 loudspeakers in multiple combinations. The cabinet is made of marine plywood with an impact-resistant paint finish. The front is protected by a rigid metal grill and an acoustically transparent foam. It's available in Special Color (SC) and Weather Resistant (WR) options. The Weather Resistant option has an IP55 rating for operation in changing ambient conditions.
