Velodyne VI-Q 12

VI-Q 12: 12-inch sealed active subwoofer

A sealed active subwoofer from the VI-Q series, with a 12" long-excursion front-firing driver and a convex carbon-fibre cone. The cabinet is 22 mm HDF with a 50 mm front baffle.

DSP, app and connections

The class D amplifier is governed by a DSP adjusted from the app: adaptation to the room, a parametric equaliser with 25 bands and presets. Besides the stereo/LFE RCA and high-level inputs there are XLR inputs and outputs. Low-pass crossover from 50 to 180 Hz, phase 0/180°.

Connecting it to the system

It connects to the subwoofer (LFE) output of a home cinema receiver or, in a stereo system, to the line outputs of the preamplifier or to the speaker terminals through the high-level input. With automatic power-on it wakes up by itself when a signal arrives and goes back to standby when the music stops.
