S20_EMOFeaturing a dual 18” subwoofer pairing in a bass reflex housing, the DVA S20 delivers powerful performance, rendering frequencies as low as 25 hertz assertively and with impressive authority.

It is the perfect sub-bass provider for DVA S10/T4 systems and an excellent complement to DVA T4 mid-/high-range units in stacked arrays.

Thanks to the integrated Quick-Release-Pins, both DRK-10 and DRK-20 frames can be easily mounted to set up a ground stacked system.

Made of sturdy birch multiplex covered in robust black textured lacquer,
the subwoofer housing is fronted with a rugged speaker grille.

The enclosure is easy to tote with its comfortable carrying handles.
