Architectural specifications
 |
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 optional.
|
|
| 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 VT-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 VT-GSUBs. |  |
|
 |
The cabinet is fitted NLT4 F/M connectors. All four pins of both connectors are wired in parallel. The VT-GSUB uses the pin assignments 2+/2–. Pins 1+/1– are designated to TOP cabinets. Using one as the input, the second connector allows for direct connection to a second cabinet. The cabinet can be supplied with NL4 M or EP5 connectors as an option.

Components
The VT-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.
Cardioid dispersion
 |
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.
