Product details

The Focal Sub One is an active studio subwoofer with two eight-inch Slatefiber drivers and 200 watts RMS of Class D amplification in total. Its twin-driver layout and large front ports are designed for low-frequency monitoring in compact production spaces.

Slatefiber drivers and cabinet design

The Slatefiber cones combine recycled carbon fibres with a thermoplastic polymer and are manufactured by Focal in France. The cabinet uses 22 mm MDF panels with internal bracing and a dark grey vinyl finish. Its narrow front profile allows placement along a wall or beneath a desk, with appropriate space for the side-mounted drivers.

Bass management for a monitor system

Balanced XLR left, right and LFE inputs support stereo or dedicated effects-channel feeds. Left and right outputs integrate satellite monitors, with selectable 60 Hz or 90 Hz high-pass filtering. Adjustable low-pass frequency, level, phase and polarity help match the subwoofer to the room and monitors. An external footswitch can control bypass for comparison while working.
