Flatsub Midi White

Flatsub Midi is a compact active subwoofer with a difference. Designed to be hung on the wall or placed on the floor under a sofa.

The bass driver is invisible at the back facing the wall, so the front is completely smooth - perfect with small children or pets in the house. Can be used with our Flatbox speakers but is also suitable to complement speakers from other manufacturers.

With variable level control, variable low-pass filter and variable phase control, it adapts to many types of listening rooms and speaker configurations. Built-in 150-watt digital amplifier with AutoStart. Available in white silk matte and gloss black piano paint finishes.
