VLF 212

The VLF212 is a compact dual 12-inch subwoofer system with a nogrille design and slot-loaded woofers for extended low frequency response down to 50 Hz in passive mode or 43 Hz using DSP. The standard install version comes equipped with twelve generous fly points for creating steered subwoofer arrays.

The VLF212 is available in an optional portable version which comes equipped with two Ergo-Grip handles, a top-mounted pole socket, and rubber feet. The portable enclosures incorporate eight fly points, dual NL4-compatible connectors and dual ¼" jacks with a high-pass output switch for running the subwoofer and a full-range cabinet from one single amp channel.

The VLF212 is a powerful and innovative low frequency subwoofer that when arrayed is effective in reducing unwanted reflections in theatres, restaurants, auditoria, houses of worship, schools and other applications, fitting comfortably into areas where larger subwoofers are impractical.
