Product Overview
The VF218SUB extended low-frequency subwoofer is designed and manufactured to provide accurate and powerful bass frequencies. It is a high-power output subwoofer system. The LA218SUB is used as a single subwoofer in a subwoofer/satellite system or as multiple subwoofers as part of an expandable large-scale sound reinforcement system with excellent efficiency and control.
