2.1 Product description
The V-GSUB is a compact high performance cardioid subwoofer
for use with d&b V-Point cabinets.
The V-GSUB houses two long excursion neodymium drivers in an
integrated cardioid setup: an 18“ driver in a bass-reflex design
facing to the front and a 12” driver in a two chamber bandpass
design radiating to the rear. The arrangement and tuning provide a
cardioid dispersion pattern using a single amplifier channel.
Its frequency response extends from 37 Hz to 115/95 Hz.
The cabinet is constructed from marine plywood and has an impact
and weather protected PCP (Polyurea Cabinet Protection) finish.
The front of the loudspeaker cabinet is protected by a rigid metal
grill backed by an acoustically transparent foam. Each side panel
incorporates two handles and mounted on the rear panel are four
heavy duty wheels. An M20 threaded flange in the top panel
accepts a loudspeaker stand for the deployment of TOP cabinets.
Two runners recessed in the bottom panel prevent cabinet
movement and protect the bottom panel against scratching.
Correspondingly shaped recesses in the top panel of the cabinet
prevent cabinet movement when stacking V-GSUBs.
In addition, the top panel has a recess in the form of the footprint
of a V-Point TOP cabinet to prevent cabinet movement when
stacking one V-Point TOP cabinet on V-GSUBs.
Cardioid dispersion
Cardioid dispersion avoids unwanted energy behind the system
and greatly reduces the excitation of the reverberant field at low
frequencies providing the greatest accuracy of low frequency
reproduction. The subwoofers can be used as stand-alone solutions
or in stacked combinations with a minimum distance of 60 cm (2 ft)
between adjacent cabinets or between the subwoofers and a side
wall. When positioned in front of walls, the minimum distance to
rear walls is maintained by the wheels mounted at the rear of the
cabinet.
