Why DVA S2585N?

DVA S2585N is born with the aim to help users who want to attenuate
the power SPL behind the stage, focusing then the directivity on the
front.
The problem of this concept is that users subwoofers configurations are
not standard: they can place subwoofers in front of the stage (Central
configuration) or at the stage sides.
DVA S2585N then had to be able to solve every particular situation wha-
tever was the subwoofers position.

An omnidirectional subwoofer’s
power response is generally consi-
dered to be a perfect sphere in
three dimensions.

Standard Omnidirectional Subwoofer

A cardioid sub is a low-frequency spe-
aker with a heart-shaped directivity.

The power attenuation for this kind
of speaker is placed at the back (180°).

Cardioid Subwoofer

A supercardioid sub is meant to
be a bidirectional low-frequency
speaker.

In this case, the power attenua-
tion is placed at ±135°.

Supercardioid Subwoofer
