HiFonics VX690A

The HiFonics VULCAN VX690A is a compact active subwoofer that delivers powerful and precise bass reproduction despite its space-saving design. The slim bass-reflex enclosure was specifically designed for vehicles with limited space for an additional bass solution.

Inside, a 15 x 23 cm (6 x 9-inch) subwoofer with a specially shaped paper cone is at work. Combined with the tuned bass-reflex enclosure, the system delivers dynamic and controlled low-frequency response. The built-in Class D digital amplifier provides an RMS output power of 150 watts and a maximum power of 300 watts.

Thanks to its high-level and RCA inputs, the VX690A can be connected to both factory-installed car stereos and aftermarket units. The automatic power-on function simplifies integration into existing sound systems, while the included backlit bass-level remote control allows for convenient adjustment of the bass level from the driver's seat.

The high-quality carpet-covered enclosure, featuring an embroidered HiFonics logo, has a subtle appearance and is particularly well-suited for small and medium-sized vehicles.
