Product Overview

High Performance Cardioid Subwoofer

The V-GSUB is an actively driven high performance cardioid subwoofer powered by a single amplifier channel. The V-GSUB is intended for ground stacked applications only, and shares the same acoustical and visual design as the V-SUB, which features integrated rigging equipment. It houses two long excursion neodymium drivers, 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 cardioid dispersion pattern resulting from this arrangement avoids unwanted energy behind the system that reduces the excitation of the reverberant field at low frequencies and provides the greatest accuracy of low frequency reproduction.

The V-GSUB top panel has a recess in the form of the footprint of a V7P/ V10P enclosure to prevent cabinet movement when stacking one TOP loudspeaker. The enclosure features two runners to protect the bottom panel from scratching. Two correspondingly shaped recesses are incorporated into the top panel of each V-GSUB cabinet to accept these runners, preventing cabinet movement when stacked. 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 of the V-GSUB panel incorporates two handles whilst the top panel has an M20 high stand flange inserted.

Amplifiers
The d&b audiotechnik loudspeaker range is designed exclusively for operation with d&b amplifiers. These provide power as well as comprehensive control and protection functions tailored to achieve the performance, reliability and longevity associated with the d&b System approach. The d&b D80 amplifier is recommended to drive the V-GSUB. The d&b D20, 30D and D12 amplifiers can also be used with the appropriate loudspeaker configuration selected.
