Velodyne SPL-X 10

SPL-X 10: 10-inch reference active subwoofer

A sealed active subwoofer from the SPL-X series, which sits at the very top of the catalogue. The 10" driver has a carbon-fibre cone, a dual spider, a basket with three ventilation channels, a 3" four-layer voice coil and a triple ferrite magnet; the cabinet is HDF with internal reinforcement.

DSP, automatic correction and connections

The class D amplifier is managed by a DSP with automatic equalisation: the microphone measures the room and the subwoofer corrects its response. The app gives access to a 6-band parametric equaliser, subsonic filter, delay up to 500 ms and presets; the low-pass runs from 30 to 200 Hz with a slope from 12 to 48 dB/octave. RCA and XLR inputs and outputs, stereo and LFE, plus a high-level input.

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.
